Welded Steel Pipe ERW SSAW LSAW DSAW

Butt Weld Fittings include elbows, tees, cross, caps and reduces. These fittings are the most common type of welded pipe fitting and are specified by nominal pipe size and pipe schedule. Buttweld fittings are manufacture by seamless or welded pipe and are formed to get the shape of elbows, tees and cross etc.

Carbon steel elbows are curved connecting pieces that join straight lengths of pipe, commonly at a 90° or 45° angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.

The lap joint stub end is required when attach the lap-joint flange to the piping system. The stub end and lap-joint flange assembly are used mainly in piping systems that necessitate frequent dismantling for inspection or routine maintenance.

90 degree steel pipe elbow functioned to change fluid direction by 90 degree, so also named as vertical elbow. It is the common degree in all the pipeline systems and used most in all different degree of elbows

BW 90 degree elbow is formed by hot forming and connects steel pipes or other pipe fittings through butt welding process. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

ASTM A182 F304 pipe fittings are inculding many fittings,among these,stainless butt welded elbows are the most common used fittings.For 90 deg elbows,there are two types :LR (Long Radius) and SR (Short Radius).Stainless steel pipe fittings are popular because of the superior functions.

Tee welding joints are formed when two pieces intersect at a 90° angle. This results in the edges coming together in the center of a plate or component in a ‘T’ shape. Tee joints are considered to be a type of fillet weld, and they can also be formed when a tube or pipe is welded onto a base plate.

It can have concentric reducer and eccentric reducer. It is widely used in pipeline installation projects, such as when the diameter of the pipeline needs to be changed at the inlet and outlet of the pump

90 deg LR (long radius) elbow is the most used type of BW elbows.Butt welded elbows also have SR (short radius) elbows.Shanghai Zhucheng has experienced pipe fittings factory that can supply high quality goods for many years.

4in BW elbow is a small dimension elbow,4in is a normal size of elbows so that this type can be used in many piping systems.Carbon and alloy steel pipe fittings are usually be chosen as the excellent functions and reasonable price.

45 degree elbow is widely used in chemical industry, food, water supply facilities, electronic industry, chemical pipeline, horticulture, agricultural production, solar equipment pipeline, air conditioning pipeline and other fields.

DN950 long radius elbow is one type of large dimension elbows,there is also short radius elbow to choose.ASME B16.9 elbow is butt welded elbow according to American Standard.

45in BW reducer is belong to large dimension butt welded fittings,STD is a commonly used wall thickness for BW fittings.Other commonly used wall thicknesses for BW fittings are SCH 40,SCH 80.

Steel pipe bend two pipes into a certain angle and connects them together to change the direction of the pipe. it could be bend directly from a finished pipe with cold bending processes, to different degrees.

When the direction change angle of the single section of the miter elbow is greater than 45, it should not be used in the pipeline with toxic and combustible media, or in the pipeline subject to vibration, pressure pulsation and alternating load due to temperature change

Branches of tees have two types:Equal tee and Reducing tee.These two types tees have same functions,but reducing tee has one more function:it can reduce the flow of the gas or fluids.Butt welded fittings are the most used fittings in many applications because the size range of the BW fittings is big.

Carbon steel elbow dimensions are different depend on the type of the elbow.BW elbows can be 1/2″-80″;SW elbow and THD elbow can be 1/8″-4″.Elbows can be made from carbon steel,alloy steel and stainless steel.Shanghai Zhucheng is an experienced pipe fittings manufacturer for many years.

ASTM A234 WPB is a common grade for 90 degree long radius elbow, which is one of the highly demanded. They available in a large size and thickness range. They have a good performance and suffices most industrial pipeline needs.

Concentric reducers will change kindly between the pump and piping， Concentric reducers are used to connect pipe segments or pipe segments on the same axis.

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 reducers are perfectly suitable to use in the exclusion of the pump. It is cone-shaped, and is used when there is a shift in diameter between pipes. A pipe reducer is available in various specifications, such as a single diameter change and also in a multiple diameter change.

BW ELBOW are installed between different lengths pipe or tubing. Its function is to change the direction of the fluid by 90 degrees, so it is also called vertical elbow.

Connect two pipes with the same or different nominal diameters to make the pipeline turn at 90 degrees, 45 degrees, 180 degrees and other angles

Butt welded reducers can be concentric (COC) reducer and eccentric (ECC) reducer.These reducers have same functions,the only difference is the internal structure.There are the BW fittings specifications in the content below.

Concentric reducer’s dimnesions and its usage and advantage

SS 304/304L elbow is stainless steel pipe fitting.304/604L is the most commonly used grade of stainless steel in American Standard.Elbows can made as 90 deg and 45 deg.Among these,90 degree elbows can be LR and SR while 45 degree elbows only have LR type.

ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on.
In these standard Grade WPB is the most common material used for medium and high temperature pipelines. W means weldable, P means pressure, B is grade b, refer to the minimum yield strength.

It can be axially shifted and externally reconfigured to offer more efficient reducer connection. Concentric reducers facilitate the delivery of mud and abrasive fluids and are suitable for corrosive operations and where different ratings and wear protection are required between flanges.
