ASTM A182 F316 Pipe Nipples ASME B16.11 Forged Fittings

Threaded couplings could be divide into full coupling (both ends threaded) and half coupling(one end threaded,the other end welded).Forged pipe fittings dimensions are all in small size,1/8″-4″.

What is a THD Uninon,what about its speicification and advantage

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.

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.

What is a Threaded Coupling,what about its specification and its advantages.

Steel pipe elbow can be divided into 3 types as buttweld, threaded, socket weld in accordance with connection. The material specification are ASTM A234, A182, A403, A105, A694, A350, A420 and A860.

The weld groove of the branch abutment is a single-sided V-shaped groove. It can be determined that the weld is a combination of butt weld (groove weld) and fillet weld.

Threaded tee used thread connection to combine with pipes.ASME B16.11 fittings are forged fittings belong to American Standard.Tees can divided as equal tee and reducing tee.These tees have same functions,the only difference is reducing tee can reduce the flow in piping system.

Swaging nipples is divided into tubing sub and casing sub. Flanging nipple in pipe connection is commonly used with flange. Diameter pipe (reducing nipple) is a pipe fitting used for straight connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

We are manufacturer of High Pressure Pipe Fittings from China. Threaded fittings are available in pressure ratings 2000LB, 3000LB, and 6000LB; Threaded Coupling Dimension is 1/8″ –  4″ / DN6 – DN100.

This is a Pipe fitting with the same size on three sides. The main pipe of these tee is different from the diameter of the branch pipe, and the diameter of the main pipe is larger than that of the branch pipe.

It is used for all kinds of equipment such as paper/pulp, petrochemical, general industrial machinery, shipbuilding, electronic equipment, vehicles, housing, water treatment, etc.

Hex head bushing is a commonly used bushing,there is also has flush bushing.Bushing is belong to forged fittings and it only available in threaded type.Threaded pipe fittings are easy to Installation and removal.

Class 3000 threaded union is the most used pressure of threaded union.ASME B16.11 is the standard for forged fittings according to American Standard.

The specification of ASTM A182 Forged Pipe Fittings includes forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.

Threaded Elbow is a pipe fitting that changes the direction of piping. According to the Angle, there are 45° and 90°180° three most commonly used. 90° Elbow material can be divided into carbon steel, alloy steel and stainless-steel.

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.

Flush Bushing: Flush bushing are used in piping systems. They are installed in the pipe to reduce the size of the pipe. Forged bushing is ideal for use with water and oil in chemical, petrochemical, pulp, paper, shipbuilding, waste incineration, and semiconductor industry applications.

The equal cross is one kind of the pipe cross,  the equal cross means all the 4 ends of the cross are in same diameter.
The reducing cross also is called unequal pipe cross , it is the pipe cross which the four branch ends are not in the same diameters.

The use of Forged End Pipe Caps is common in many industries such as oil and gas industries, chemical industries and water supply lines.

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.

Thread Types:

NPT  PT  BSPP  BSPT  PF

Concentric swage nipple is mainly used for vertical pipeline. t is used to change the diameter of the pipe and connect two pipes of different sizes.

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.

Threaded fittings are mainly used for small pipe diameters, generally for piping whose nominal diameter is NPS 2 or smaller. Threaded joints probably represent the oldest method of joining piping systems.
