Размеры отвода 90 градусов: Отводы стальные ГОСТ. Размеры и вес стальных отводов

ГОСТ 17375-83* «Детали трубопроводов стальные бесшовные приварные на Ру 10 МПа ( 100 кгс/см2). Отводы крутоизогнутые. Конструкция и размеры»

Отводы стальные крутоизогнутые по ГОСТ 17375-2001 и ГОСТ 30753-2001

Отводы крутоизогнутые цельнотянутые изготавливаются методом штамповки или протяжки по рогообразному сердечнику. Такие отводы стальные имеют незначительный радиус кривизны (1-1,5 условного диаметра) вследствие чего обладают небольшим весом и габаритами. Отводы крутоизогнутые изготавливаются под углами в 30, 45, 60, 90, а также 180 градусов (калачи). На рисунке, приведенном ниже, вы можете посмотреть как схематично выглядят отводы крутоизогнутые цельнотянутые:

Отводы стальные крутоизогнутые цельнотянутые:

Отводы цельнотянутые бесшовные изготавливаются по ГОСТ 17375-2001 и ГОСТ 30753-2001 и бывают первого и второго исполнения. Отводы по ГОСТ 17375-2001 имеют радиус кривизны равный 1,5 условного диаметра, а отводы по ГОСТ 30753-2001 имеют радиус кривизны равный условному диаметру. Отводы, изготовленные согласно ГОСТ 17375-01 и ГОСТ 30753-01 могут выдерживать давление до 16МПа, за счет того, что не имеют ни одного сварного шва, поэтому если в монтируемом трубопроводе предполагается высокое давление, то для данного трубопровода применяют отводы цельнотянутые по ГОСТ 17375-01 или ГОСТ 30753-01. В нижеприведенных таблицах указаны все виды крутоизогнутых отводов первого и второго исполнения по ГОСТ 17375-2001 и ГОСТ 30753-2001 поставляемые нашей компанией, а также все характеристики данных отводов:

Ниже приведены примеры условных обозначений отводов по ГОСТ 30753-2001:

Отвод 90°, исполнения 2, диаметром 159 мм, толщиной стенки 6 мм из стали марки 09Г2С:

Отвод 90-2-159х6-09Г2С ГОСТ 30753-01

Отвод 45°, исполнения 1, диаметром 76,1 мм, толщиной стенки 5 мм из стали марки 20:

Отвод 45-1-76,1х5-20 ГОСТ 30753-01

Таким образом видно, что радиус гиба, а значит и строительная длина отводов изготовленных по ГОСТ 30753-2001 меньше чем у отводов изготовленных по ГОСТ 17375-2001, в этом и есть отличие ГОСТ 17375-01 от ГОСТ 30753-01.

Не смотря на то, что цельнотянутые отводы выдерживают большее давление, чем отводы, изготовленные любым другим способом — их стоимость выгодно отличается в меньшую сторону, за счет технологии изготовления, при которой практически не остается отходов.

Если Вам нужно узнать вес отводов, изготовленных под углами в 30°, 45° или 60°, вам просто нужно умножить вес отвода, указанный в таблице на коэффициенты 0,4, 0,5 и 0,7 соответственно и вы всегда сможете точно рассчитать стоимость транспортных расходов, воспользовавшись вышеприведенными таблицами.

Наша компания может поставлять отводы по ГОСТ 17375-2001 и ГОСТ 30753-2001 из различных марок стали, таких как: сталь 20 и 09г2с (отводы стальные), сталь 12х18н10т, 10х17н13м2т (отводы нержавеющие), сталь 15х5м (отводы жаропрочные) и д.р.

На все цельнотянутые отводы, поставляемые нашей компанией выдаются паспорта качества, разрешение на применение, а также сертификат соответствия.

Если у вас остались вопросы, связанные с с отводами крутоизогнутыми цельнотянутыми, Вы можете задать их менеджерам нашей компании по электронной почте soiuzdsk@mail.ru или по телефону +7 (343) 361 2377

90000 Tap Size Chart — Machining 90001 90002 The tap size chart provides a list of standard size taps, specifying the diameter and thread spacing, for fractional, metric, and screw sizes. The decimal equivalents of the diameters are shown in both English and Metric units. Fractional sizes are listed in inches, while metric sizes are listed in millimeters following the letter «M». A screw size number corresponds to a diameter which is larger for a higher screw size.The thread spacing, which may be coarse or fine, is listed after the diameter. In the fractional and screw size systems, the thread count is used, measured in threads per inch. The metric system uses the thread pitch, which is the distance between threads, measured in millimeters. For each thread count, the equivalent thread pitch is provided and for metric taps, the approximate thread count is shown based on the pitch. Lastly, the recommended tap drill size is provided for each standard tap size.This size drill bit should be used for drilling the initial hole that will then be tapped. 90003 90004 Downloadable

print and post in your workshop, scroll on down. 90002 But, before you do, would not you like to hear about something that’s much better in every way? Something that’ll make it much less likely you’ll break a tap? Something a little more modern than a simple chart? 90003 90002 Let us help, and BTW, 90005 it’s completely free too 90006! 90003 90002 90009 90003 90002 What’s better than a drill bit size chart? 90003 90002 Make no mistake: having a good drill bit size chart (sometimes called a «drill index») is a very handy thing indeed to have around.If it has information on which twist drill size to use for tapping, so much the better. But in this age of computers and the Internet, you can do better. 90003 90015 Newsflash: There Is not Just One Drill Bit Size for a Tap 90016 90002 Let’s start with an important fact-there is not just one drill bit size to use for a given tap size. There are several. Moreover, the size recommended in most drill bit size charts is very often not the best size to use. The same is true of the size recommended on the tap and even the recommended size from the tap manufacturer.Anytime you see just one size being recommended, you know you can do better-one size does not fit all when it comes to tapping. How can that be? Well, it’s actually pretty simple. To know which drill bit size is right for your particular tapping application, you need to consider what 90005 thread percentage 90006 you want when you’re done tapping. 90003 90015 What’s Thread Percentage and Why Care? 90016 90002 Imagine the fully formed internal thread. Each thread rises from valley to peak.Now suppose you ran a twist drill down the hole and shaved off some of the peaks. They’re pretty delicate anyway and will wear off quickly. In fact, they contribute surprisingly little strength. Kennametal says a 100% thread is only 5% stronger than 75% thread. But here is the real kicker: That 100% thread requires 3 times the power to tap! Why do you care? because it is the power to tap that breaks taps, for one thing. Getting 95% of the strength with 1/3 the force on the tap means you’re dramatically less likely to break the tap off in the hole.Now we all know what happens when we break a tap, right? Sailors would go running out of the shop if they heard the language we use in that case. It’s just not a happy thing. But is it okay to have less than 100% threads? In fact, many standards bodies insist on it. For example, American National and Unified thread specifications provide for a maximum of 83 1/3% thread. These specifications also provide a minimum value that varies from approximately 53% to 75%, depending upon the diameter and pitch of thread.90003 90015 Thread Percentage and Tap Drill Charts 90016 90002 Most tap drill charts call out only one tap drill size, and that will produce an approximate 90028 75 percent 90029 thread. For most applications, you can get longer tap tool life and lower likelihood of breaking a tap off in the hole by using a lower percent of thread. Companies like Guhring actually recommend 60% to 70% percentage of thread for most applications because it significantly lowers the torque force required to tap without giving up much thread strength.That’s why these lower percentage are a better idea for your tap’s tool life! 90003 90015 Thread Percentage vs Strength Chart 90016 90002 Let’s take a closer look at the relationship between torque and thread strength based on thread percentage: 90003 90002 90036 90003 90002 90005 Red 90006 marks the typical 75% percent of thread drill recommendation. Chart courtesy of Tapmatic. 90003 90002 Red marks the typical 75% percent of thread drill recommendation. What stands out is the relationship between the torque required to tap (solid black line) and the strength of the tapped hole (dashed line).When We accept the 75% percent of thread the average drill chart hands us, we’re subjecting our poor taps to a huge amount of additional torque for very little extra strength! 90003 90002 Is it any wonder the darn taps give up and break on us after that kind of abuse? 90003 90002 So what’s the right way to choose a thread percentage and how do we get from there to a proper drill size? 90003 90015 General Guidelines for Choosing Thread Percentage 90016 90002 Try this approach, which is based on material and type of work: 90003 90002 90053 90003 90002 The material matters because we can afford higher thread engagement in softer materials and we actually need it to increase thread strength.For hard or tough materials, a lower percentage can really help tap life and those materials have lots of strength even at the lower percentages. In deeper holes, we run the most risk of breaking a tap and in sheet metal we need the strongest threads because there is much thread depth for holding power. 90003 90015 Tapping Drill Size Problem # 2: Form Taps vs Cut Taps 90016 90002 Just one more little wrinkle is that Form Taps (also called «Roll Taps» because they perform thread rolling rather than thread cutting) need a different sized hole than Cut Taps, and most drill size charts only show drill sizes for Cut Taps.As a machinist, you’re no doubt aware of the many advantages Form Taps have over Cut Taps: 90003 90061 90062 Form Taps do not make any chips. This is a huge advantage when threading deep holes and especially for blind holes where chips can jam up in the bottom of the hole. 90063 90062 Form Taps make stronger threads than Cut Taps. What could be better? 90063 90062 Better Thread Gaging. Form taps work by cold forming the metal in the hole. Since no chips are made, the likelihood of producing oversized threads is far less than for Cut Taps.90063 90062 Stronger Taps. It just gets better and better-form taps are stronger and less likely to break than cut taps. 90063 90062 Longer Tap Life. Form taps, properly used, can last 3 to 20 times longer than cutting taps because they have no cutting edge to dull. 90063 90062 Faster Tapping. You can run higher spindle speeds with form taps than cut taps. 90063 90074 90002 In fact, the main disadvantage of Form Taps is they can not be used on materials that are too hard. The hardness limit for Form Taps is higher than you probably think (they’re good for much more than aluminum), but there is a limit nonetheless.Given all that, you’re definitely going to need to figure out Form Tap Drill Sizes too! 90003 90002 90005 Quick Tip 90006: If you’re wondering about the different types of thread taps, click the link for our complete guide. 90003 90002 90082 90003 90015 How Do I Go From Thread Percentages to Tap Drill Size? 90016 90002 Well, you can not use a standard drill chart, that much is clear. You could calculate the optimal size for a particular percentage of thread and then go to a standard drill chart to find the nearest size.That works, but it is a fair amount of trouble. 90003 90002 I promised you a better way, and here it is-you can use our G-Wizard Calculator’s Thread Database to tell you exactly what you need to know, and it is very fast and easy to do so. Let’s walk through it: 90003 90061 90062 Go to the Thread Database in G-Wizard by selecting the Threads tab. 90063 90062 Choose which thread you want. G-Wizard has a bunch of them in its database. 90063 90062 In the lower left corner is a convenient table of tap drill sizes with a column showing thread percentage.You can even select Form or Cut Taps to change the drill sizes. 90063 90074 90002 Here’s what it looks like: 90003 90002 90101 90003 90002 Tapping Drill Chart for 1 / 4-20 Thread 90003 90002 Nice, huh? It saves people a lot of time. There’s a whole ton of other very handy reference time savers there too, not to mention the world’s best Feeds and Speeds Calculator. I’ve all but quit having to dig through my Machinery’s Handbook to find information-I just use G-Wizard. 90003 90002 Here’s something else-you can get lifetime access to all the reference calculators and materials except the Feeds and Speeds Calculator just by signing up for a Free Trial of G-Wizard.That’s right, it is completely free to access all that just by signing up for a free trial and you’ll also get all the upgrades and customer service for life! Plus, buy the $ 79 version and you get up to 1 HP on the Feeds and Speeds too for life. 90003 90002 So what’s the catch? Why does anyone ever pay more than $ 79? 90003 90002 Many hobbyists do not pay more than $ 79, BTW. The catch is a spindle power limit. When you buy the 1 year G-Wizard for $ 79, you get 1 year of unlimited spindle power for Feeds and Speeds.When that expires, you get a spindle power limit of 1 HP. That limit is based on however many years you subscribe for. You can increase it any time you like by renewing the subscription. Or, if you do not like subscriptions, you can also by the product outright. And we never charge for updates or customer service. 90003 90002 So go ahead, give G-Wizard free trial, a try. You’ll be surprised at all the time it saves you on things like Tap Drill Sizes, not to mention the longer tool life, better surface finish, and shorter cycle times you’ll get from better Feeds and Speeds.90003 90015 Bonus: Depth Clearance When Tapping Blind Holes 90016 90002 Blind Holes are particularly prone to breaking taps. It’s harder to clear the chips for one thing, but the other thing is machinists do not leave enough clearance at the bottom of the hole. 90003 90002 Most do not even know how much clearance they should be leaving. But, G-Wizard will calculate the clearance for you. Just one more way it’s saving you time and trouble. 90003 90015 Hey, What About that Free Drill Bit Size Chart? 90016 90002 Here you go, Metric and Imperial sizes are called out in the «Use» column in
