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.
