Hexagonal nipples NPS 1/8″-3″ ASME B16.11

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. Threaded Steel Coupling is a short piece with screw in NPT or BSP ends or one end, which is available in stainless steel, alloy steel and carbon steel.

The branch pipe stand is also called branch pipe seat, saddle and saddle type pipe joint. Reinforced pipe fittings mainly used for branch pipe connection, instead of branch pipe connection such as reducing tee, reinforcing plate and reinforced pipe section

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.

CL3000 threaded coupling is the most used pressure of couplings.ASTM A105 forged fittings are pipe fittings in material of carbon steel.ASTM A105 specification is also including forged flanges.

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

Threaded elbow can reduce pipeline stress and pressure drop reduce pipeline stress, reduce pipeline pressure drop, and reduce pulsating power of fluid to pipeline.

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.

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.

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.

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.

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.

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.

The base of the threaded branch pipe stand is the same as that of the butt welded branch pipe stand, but its branch connection is screw connection, which does not require welding. The threaded branch pipe has two pressure classes, 3000 # and 6000 #.

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

Type: Full and Half Coupling
Shape: Straight and Reducing Coupling
Thread Type: NPT, PT, BSPP, BSPT, PF
Size Range: 1/8″ – 4″ / DN6 – DN100

Equal tees are available in sizes from half an inch to 48 inches (or larger) and in seamless and welded execution (seamless up to 24 inches, welded for tee sizes above 24 inches).

Thread Types:

NPT  PT  BSPP  BSPT  PF

Carbon steel threaded tee is a pipe connector made of carbon steel material, with three threaded interfaces, used to connect three pipes, one of which is used as a branch port. It realizes the medium diversion in the pipeline system and ensures the normal operation of the pipeline system.

Pipe Nipple is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings.

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.

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.

Steel pipe elbow can be divided into 3 types as buttweld, threaded, socket weld in accordance with connection.Threaded elbow is more convenient compare with the buttweld and socket weld elbow.

Forged threaded elbows are very common in chemical, oil refining, petrochemical and other industries, and are also used in some other industries.

A combination of pipe nipples are recommended for low-pressure discharge and suction service for various compatible liquids and not for compressible products like air, nitrogen or steam. 

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.
The Alloy Steel A182 Threaded Elbow material grade contains ASTM A182 F11 / 12 / 5 / 9 / 91 / 92 / 22.
