Buttweld A234 WPB Seamless Pipe Fittings

buttweld A234 WPB carbon steel and alloy steel pipe fittings from hot process

Hydraulic Elbow Carbon Steel Buttweld A234 Wpb Seamless Pipe Fittings
Product Description:
 

ASME B16.9 elbow has been produced by the pipe . Firstly, we need cut the pipe into piece and then we put the elbow om the induction hot forming elbow machine . After forming the carbon steel elbow and we need to sizing the carbon steel elbow and after we need d beveling , shot blasting , painting ,marking and package . Then the whole process production line will be finished . For the different size and thickness elbow ,we can get from the mandrel . Then size different the mandrel different . The thickness is different and the mandrel is also different . Different bend radius needs different mandrel . So producing ASME B16.9 elbow needs many mandrels for different model.

What is a bend?
In piping systems, elbow is the piece of pipe that redirects the pipe.According to the Angle, there are 45° and 90°180° are the three most commonly used, and other abnormal Angle elbows such as 60° are also included according to the engineering needs.Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.Connection with the pipe: direct welding (the most common way) flange connection, hot melt connection, electric fusion connection, thread connection and socket type connection.According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow and so on.Other names :90 degree bend, right Angle bend, love and bend, etc.
 
 
 
 

technical requirements

1. Since most pipe fittings are used for welding, in order to improve welding quality, the ends are beveled with a certain Angle and a certain edge. This requirement is also strict.The surface mass and mechanical properties are basically the same as the pipe.For the convenience of welding, the fittings are the same type of steel as the connected pipe.

2, that is, all the pipe fittings have to go through the surface treatment, the inner and outer surface of the oxidized iron sheet through the peening treatment, and then painted with anti-corrosion paint.This is for export needs, moreover, in the domestic is also for the convenience of transportation to prevent corrosion and oxidation, must do this aspect of the work.

3, is the requirement for packaging for small pipe fittings, such as exports, we need to make wooden cases, about 1 cubic meter, stipulated that the number of elbows in this kind of box can not exceed 1 ton, the standard allows the set, that is, large set small, but the total weight generally can not exceed 1 ton.For large pieces of y you need a single package, like 24 "you need a single package.Another is the packaging mark, mark is to indicate the size, steel, batch number, manufacturer's trademark.

 
 
Classification:

By the production method can be divided into push system, pressing, forging, casting and so on.

It can be divided into national standard, electrical standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.

According to its radius of curvature, it can be divided into long radius elbow and short radius elbow.The long radius elbow refers to the outer diameter of the pipe whose radius of curvature is 1.5 times, that is, R= 1.5d;The short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, i.e. R= 1.0d.(D is the diameter of the elbow and R is the radius of curvature).

According to the pressure level, there are about 17 kinds, which are the same as the American pipe standard :Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, SCH100, Sch120, Sch140, Sch160, XXS;The most common ones are STD and XS.
