Stainless Steel Tube Fitting Threaded Coupling

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.

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.

The main purpose of using pipe caps is to waterproof the connections. They are also used to close the the ends of hydraulic or pneumatic pipes and tubes. The use of Forged End Pipe Caps is common in many industries such as oil and gas industries, chemical industries and water supply lines.

SS304 90 deg elbow is a stainless steel pipe fitting used to changes the direction of the flow in 90 degree.Threaded steel pipe fittings are a type of forged steel pipe fittings.The other forged fitting is SW pipe fitting.

Concentric BW reducer is a tpye of reducers,there is also eccentric reducer to choose.BW reducers used to reduce the flow of the fluids in the piping system.Stainless steel pipe fittings are popular because the superior functions.SCH 40 and SCH 80 are the commonly used wall thicknesses in butt welded fittings.

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.

A threaded bushing, also known as a threaded insert, is a fastener element that is inserted into an object to add a threaded hole. Bushing Threaded Types: NPT  PT  BSPP  BSPT  PF.

The threaded pipe union is similar to the coupling and can be flexibly disassembled when it needs to be repaired or replaced. The reducing threaded union is easy to disconnect and link, and can be operated multiple times.

ASTM A182 F304L forged fittings are high pressure pipe fittings which can used in many industries because of the excellent functions.DN25 threaded pipe tees are small size fittings but an indispensable part in piping systems.

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 pipe fittings provide permanent welded connections for pipes. Threaded joints probably represent the oldest method of joining piping systems. Same as Socket Weld fittings, threaded fittings are mainly used for small pipe diameters (Small Bore Piping); generally, for piping whose nominal diameter is NPS 2 or smaller.
They are available in three pressure ratings: 2000lbs, 3000lbs and 6000lbs.

British Standard Pipe Parallel (BSPP)

F316 threaded  caps are components used to close the ends of stainless steel pipes or pipe fittings, and achieve the functions of sealing and fixing through threaded connection.

BS3799 F304 Threaded Pipe Fittings are named by its manufacturing forging process and produced according to ASME B16.11, MSS-SP-79\83\95\97 and BS3799 standards.

Carbon steel pipe fittings are used in many applications because of its great excellent functions.Carbon steel pipe fittings can manufactured as THD (threaded) fittings,SW (socket weld) fittings and (BW) butt welded fittings.The specifications are in the content below.

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.

High pressure Stainless Steel A182 Threaded Tee is used for providing branch, it can be divided into equal tee and reducing tee. The common used dimension is DN15, DN20,DN25 and DN40 for socket weld tee and threaded 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.

hat is a threaded tee,what about its specification and its difference between a elbow.

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.

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.

Carbon Steel ASTM A105 / A105N, ASTM A350 LF2/LF3, ASTM A694 F42 / 46 / 56 / 60 / 65, P235GH, P265GH, P280GH, P355GH
Alloy Steel: ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 / 22

Duplex Stainless Steel: ASTM A182 F51, F53, F44

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.
