Carbon Steel Pipe Fittings

Steel pipe tee is a pipe fitting used to tansport the flow in the piping system.Carbon steel fittings are used in many applications becasue of its great excellent functions.

Socket Weld Coupling material can be divided into carbon steel, alloy steel and stainless-steel, and the pressure ratings is Class 3000, 6000, or 9000.

Swaging nipple (also known as reducing nipple) is a forged pipe fitting. It is used to change the diameter of the pipe and connect two pipes of different sizes.

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

BW tees and reducers are the most used pipe fittings in the piping system.Tees can branch the flow in piping systems.Carbon steel pipe fittings are popular as the great functions and affordable functions.

Steel pipe bend is belong to butt welded fittings,bends have some similar usages as elbows.However,bends can be customized by clients to satisfy different demands.Schedule 80 is represents to the wall thickness of BW fittings.The most used wall thicknesses of butt welded fittings are SCH 40,SCH 80.

Swage nipples are often used in small diameter pipe systems, and are similar to pipes. It is used to allow plumbing to be connected to a water heater or other plumbing.

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. 

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

Pipe tee is a commonly used pipe fittng used to branch the flow in piping systems.There are two types of tees:Equal Tees and Reducing Tees.SCH XS is a wall thickness of butt welded fittings,SCH XS is large wall thickness which can resists higher perssure.The most used wall thicknesses are SCH 40 and SCH 80.

Steel pipe bend is belong to butt welded fittings,bends have some similar usages as elbows.However,bends can be customized by clients to satisfy different demands.API 5L B is a grade of carbon steel material for pipes and bends.

According to its radius of curvature, there are long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R=1.5D; A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d.(D is the diameter of the elbow, and R is the radius of curvature).

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.

Concentric Swage Nipple and Eccentric Swage Nipple. Like Pipe Reducer, Concentric swage nipple is symmetrical, both ends are aligned along the center, used in vertical pipes, Eccentric swage nipple is not symmetrical, ends are off center of one another and used in horizontal pipes..

ASTM A105 Swage Nipple is a type of carbon Steel Pipe Fittings and commonly used for connection two pipes with different diameters. It belongs to pipe reducers and are used in small pipe size more often.

Swage niples belongs to pipe reducers and are used in small pipe size more often. It has two types: Concentric Swage Nipple and Eccentric Swage Nipple.

Concentric swage nipple is symmetrical, both ends are aligned along the center, used in vertical pipes, Eccentric swage nipple is not symmetrical, ends are off center of one another and used in horizontal pipes.

Carbon steel tee is the most used type in all tees because carbon steel has great functions and affordable price.Galvanized pipe fittings has better anti-corrosive function than normal carbon steel pipe fittings,galvanized fittings have similar functions as stainless steel fittings,but the price is cheaper than stainless steel fittings.

BW carbon steel reducer is the most used type of BW reducers.Butt welded reducer can be concentric (COC) reducer and eccentric (ECC) reducer to meet different demands.SCH 160 fittings are belong to large wall thickness,these fittings can resist high pressure in piping system.

Steel bend is almost same as pipe elbow. It’s radius is bigger and extensive used in oil and gas, engineering and construction industry.

Concentric reducer is used to join pipe sections or tube sections on the same axis. It is cone-shaped, and is used when there is a shift in diameter between pipes.
