ASME B16.11 Stainless Steel High Pressure Thread Union Fittings

Threaded Union used in different industries applications like chemical processing, oil refineries, petrochemical and many other industries.Our offered Threaded Union Fitting is Stocked for Immediate Shipment.We are also supplier of Threaded Dielectric Union which breaks the electrical path with a plastic liner between its halves, limiting galvanic corrosion.

Forged Olets Pipe Fitting is generally made of integral forging. The structure of the weldolet is divided into main pipe connection end, reinforcement part and branch pipe connection end.

Threaded elbow used thread connection to connect with the pipes.Pipe elbows have three types:THD (threaded),SW (socket weld),BW (butt welded).These elbows used different connections to connect with the pipes in piping system.Class 3000 forged fittings are the most used high pressure fittings.

Used for all sorts of media: chemical substances, petrochemical products, liquefied gas – especially in loading/unloading applications. There are also couplings intended for highly aggressive chemical substances, lined with ECTFE – a polymer resistant to chemicals.

We are the manufacturer of High Pressure Steel Pipe Fittings for China. Pipe Coupling contains Socked Coupling and Threaded Coupling.

ASME B16.11 is the standard of both socket-welding and threaded. Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000;
Socket welding fittings are available in pressure ratings Class 3000, 6000, and 9000.

In small diameter pipes (below DN50), reducing nipples are also often used to replace reducing joints for pipe reducing. Reducing nipples also have concentric and eccentric parts

Especially in high-pressure, high-temperature, large-diameter and thick walled pipes, it is increasingly used, replacing the traditional branch connection method.

Swage nipple is a common accessory in industrial pipeline connection. Common threaded short joints are divided into double head external thread, single head external thread, flat head external thread, and short joints connected by flanges.

Carbon Steel A105 Threaded Tee are commonly used carbon steel grade which is used to manufacture forge piping components such as forged fittings and flange of small diameter piping, generally for piping whose nominal diameter is NPS 2 or smaller.

A swage nipple is something similar to that of a reducer but it is used to join the butt welded pipe with a socket welded or screwed pipe.Like the reducer,swage nipple is also available with two variations:concentric swage nipple and eccentric swage nipple.The swage nipple generally adopts the MSS SP-95 or the BS3799 Standard.

Shapes:

Concentric: Concentric swage nipple is mainly used for vertical pipeline.

Eccentric: eccentric swage nipple is mainly used in horizontal pipelines.

3000LB threaded couplings have the most widely using range.ASTM A105 forged fittings is carbon steel fittings belong to American Standard.Threaded couplings have two types:Half and Full.The other pressures could be chosen:#2000,#6000.

High pressure forged steel tee is used for providing branch, it can be divided into equal tee and reducing tee.High pressure tee is used for adding pipe branchs. An equal tee, otherwise called straight tee, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee.

Threadolet has the same basic design as a weldolet. The commonly used manufacturing standards of the branch stand include MSS sp-97, GB / t19326 and other standards.

Full Coupling: Both ends of the full thread coupling are threaded. Half Coupling: One end of a half thread coupling is threaded and the other end is welded.

The basic difference between couplings and unions in use is that couplings connect pipes to pipes or pipes to bends.Unions are used to connect and disassemble part of the piping system for maintenance or replacement.

ASME B16.11 forged fittings are popular because of the famous American Standard and the variety products.Socket weld (SW) fittings and threaded (THD) fittings are both forged fittings.Stainless steel pipe fittings are always chosen in corrosive and chemical environments.

The coupling is used to make connection of two pipes. The maiterial is available in stainless steel, alloy steel and carbon steel. The size range is DN6-DN100.

There are various types of ASME B16.11 socket-welding fittings, such as Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, Union and Sockolet; while ASME B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.

Swaging nipple (also known as reducing nipple) is a forged pipe fitting. It is used to change the diameter of the pipe and connect two pipes of different sizes.

Threaded couplings used thread connection to connect two pipes.Threaded coupling is belong to forged steel fittings.The other type of forged fitting is socket weld fittings.All the forged fittings are high pressure pipe fittings.

Stainless steel threaded pipe fittings are very popular forged fitttings because of the excellent anti-corrosion function.ASME B16.11 forged pipe fittings are SW pipe fittings and THD fittings.There are threaded pipe fittings in the picture.SHANGHAI ZHUCHENG PIPE FITTINGS MANUFACTURING CO LTD is an excellent pipe fittings and flanges supplier from China.
