Asme 24 Inch Seamless Pipe Fittings 90 Degree

Seamless and Semi Seamless Black Painting Buttweld Pipe Fittings

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.
