ASME B16.9 Stub End is a combination of a stubs end and a short piece of pipe. The short piece of pipe is welded to the pipeline of similar diameter and wall thickness. R.C. Metal Corporation is a leading manufacturer and supplier of the Long Neck Stub End and other types. The long neck ones have longer necks or stubs where there are short necked stubs ends called Short Stub End Pipe Fittings are also available. The advantage of this fitting is that it has a flared end facing outwards so that it could have a better connection. The Stainless Steel Stub End types are the most commonly used. The 304 grade austenitic stainless steel is used the most. And there are other materials such as the carbon steel to produce Carbon Steel Pipe Stub End.
The carbon steel products are preferred for the high toughness. They have high impact strength and they can withstand high impact, wear and tear conditions. There are different types such as the MSS SP-75 Stubs End Type A type B which are used in different application circumstances. There are special models such as the Lap Joint Stub End which has an additional lap joint to make the connection even secure and robust. We manufacture the Stub End Buttweld Fittings in welded and seamless types. The welded ones are most common where the seamless ones are more accurate in sizes.
The different standards and scales such as the MSS SP-43 Type B Stub End are available in the market. The applications differ such as petroleum, petrochemical, oil and gas, power generation, sea water applications, marine applications, pollution control systems and so on. There are different standards such as the Stubs End DIN 2642 that are used for these different applications. Some applications require strength while some other requires corrosion resistant and yet others require toughness. The Stubs End EN 1092-1 type 35 is one such specification that is needed for high pressure application types. Please feel free to contact us for the most used Stub End SS 304, other grades and the price list.
