Stainless Steel ASTM A182 Threaded Coupling Dimensions

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.

ASTM A182 F316 pipe nipples have two shapes:TOE (threaded one end) and TBE (threaded both ends).The nipples in the picture are all in TOE shape.The pressures can be chosen:CL2000,CL3000,CL6000.

Shapes:
Equal：This is a Pipe fitting with the same size on three sides.
Reducing：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.

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 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.

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).

What is a treaded nipple,what about its specification and its difference between coupling.

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.

B16.11 threaded fittings can be furnished in product forms of Elbow, Cross, Tee, Coupling, Half Coupling, Boss, Cap, plug and bushing.Threaded fittings are available in pressure ratings Class 2000, 3000, and 6000;

Pipe Swage Nipple (also known as reducing nipple) is divided into tubing sub and casing sub. Flanging nipple in pipe connection is commonly used with flange.

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

Swage Nipple are similar to reducers, but they’re smaller, and they’re used to link larger screwed, or socket welded pipes to smaller screwed or socket welded pipes. They come in concentric and eccentric varieties, just like reducers. Swages come in a variety of end

They have applications in many industries,including chemical processing, petroleum, refining, marine waste treatment, utilities / power generation, industrial equipment, natural gas compression and distribution industries. Tee pipe is also recommended for industrial equipment hydrodynamic system

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.

Threaded coupling is used to connect two pipes with threaded connection.Forged steel pipe fittings can divided into SW (socket weld) fittings and THD (threaded) fittings.

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.

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. 

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

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

ASTM A182 F316 is a popular grade for stainless steel in American Standard.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.

ASTM A182 F304 threaded half nipples, are nipples with one end thread and the other end weld. The other shape of nipples are threaded full nipples,which are both ends with thread.Pipe nipples also have sock weld connection,they are similar to threaded nipples,the only difference is threaded nipples use thread,while SW nipples use socket welded.

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.

Carbon Steel A105 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. Elbow material can be divided into carbon steel, alloy steel and stainless-steel.
