Butt-Weld Pipe Fittings/90 Deg. Elbow/Short

90 degree elbow’s usage and its specification

ASTM A234 WPB Butt Welded Fittings are the best selling products in Shanghai Zhucheng Pipe Fittings Manufacturing Co Ltd from China.We can also supply customers forged pipe fittings,pipes and some related products.

A234 WP11 elbow is a pipe fitting used to change the direction of the pipeline. It is made of alloy steel. Its basic structure is a curved tubular part, usually with connection interfaces at both ends to connect with other pipeline components.

The butt welded eccentric reducer is a pipe fitting used to connect pipes of different diameters, and its central axes do not overlap, and there is an eccentricity.

Carbon Steel Pipe Fittings Elbow is a most common type of CS fitting used to join pipe or tubing to allow a change of direction, usually a 90° or 45° angle, Elbows ends may be machined for butt welding , threaded , or socketed

24IN carbon steel BW elbows are large dimension fittings,ASME B16.9 is represents butt welded fittings in American Standard.Carbon steel fittings are used in many applications because of its great excellent functions.

The stub end is usually a short section of pipe fittings, with one end being a flap structure, and the other end can be a stub end or special processing according to specific needs. The turning part is designed to facilitate the connection with other pipe fittings or equipment.

12 IN Carbon Steel Elbow is an important pipe fitting in piping system as it can change the direction of the pipes in 90 degree.ASTM A234 WPB is a commonly used grade for carbon steel in American Standard.

ASME B16.9 tee is a butt welded tee .ASME B16.9 is American Standard for BW fittings.Carbon steel fittings are always been chosen because of the great functions and affordable price.

Steel pipe tee has three types: BW (butt welded),SW (socket welded),THD (threaded).The branches can be equal and reducing.Shanghai Zhucheng is a superior pipe fittings supplier who provide high quality pipe fittings and forged flanges in years.

Steel pipe elbow is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters, and to make the pipe and thus the fluid direction turn to a certain direction of 45 degree or 90 degree. This change in fluid flow direction adds pressure losses to the system due to impact, friction and re-acceleration.

90 degree steel pipe elbow functioned to change fluid direction by 90 degree, so also named as vertical elbow. A 90 degree elbow attaches readily to plastic, copper, cast iron, steel and lead. It can also attach to rubber with stainless steel clamps. Available in many materials like silicon, rubber compounds, galvanized steel etc.

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.

A pipe tee isuaually used in different industries,petroleum, natural gas, chemical, water and electricity, building and boiler industries.What’s the advantage ,how to choose a suitable tee ?

Concentric reducer’s dimnesions and its usage and advantage

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.

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.

Pipe elbows have three types:THD (threaded),SW (socket weld),BW (butt welded).These elbows used different connections to connect with the pipes in piping system.Stainless steel fittings are popular because of the an-ti corrosive function.Stainless steel fittings can used over 50 years.

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 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.

Steel pipe bend is belong to butt welded fittings.The bend radius R should greater than or equal to 3 times of the outside diameter.Bends could manufacture as the customize degree to meet the client’s demends.

90 deg stainless steel elbow is a popular type of elbows.Stainless steel pipe fittings are popular because of the an-ti corrosive function.Stainless steel pipe fittings can used over 50 years.Shanghai Zhucheng is an excellent pipe fittings manufacturer who supplys high quality pipe fittings and flanges for years.

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.

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
