MSS SP-97 Threadolet NPT Pipe Fittings

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.

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.

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

Stainless steel 90 deg threaded elbow is popular because it is easy to install or replace.ASME B16.11 forged fittings are pipe fittings according to American Standard.There are many types fot customers to choose:NPT PT BSPP BSPT PF.

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.

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.

Bending radius less than or equal to 1.5 times of pipe diameter belongs to elbow, and bending radius greater than 1.5 times of pipe diameter belongs to elbow

High Pressure Steel Pipe Fittings contain buttwelding pipe fittings, socked weld fittings and threaded pipe fittings. 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 size range is DN6-DN100. There are various grade of A694 Threaded Coupling, Such as A694 F42 / 46 / 52 / 56 / 65 / 70

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;

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.

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.

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 size range is DN6-DN100.

Forged 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. It is a connector in between nominal bore pipes. Their material can be made of carbon steel A105 and stainless steel SS316 & 304.

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.

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.

Weldolet, an economical butt-weld branch connection, is designed to minimize stress concentrations and provide integral reinforcement. manufactured to meet your specific reinforcement requirements.

Reducing pipe (reducing nipple) is a pipe fitting used for straight-line connection of two pipes with different sizes to realize pipe diameter reduction. There are concentric reducing joints and eccentric reducing joints

Socket Weld Half Couplings is utilised in various applications in order to provide a torque free sealing and a leak free connection. Socket weld coupling is a very short section of pipes with socket bore at both ends or one end, but both can afford high pressure of 3000#, 6000#, 9000#. The Socket Weld Half Coupling are often directly welded to the run pipe, to form a branch connection.

This is a Pipe fitting with the same size on three sides. It is used to change the direction of the pipe so that the pipe is 90 degrees perpendicular to the pipe.

We are the ISO certified manufacturer who produce and export ASME B16.9 and ASME B16.11 Steel Pipe Fittings. 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 size range is DN6-DN100.

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.

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.

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.
