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.

Hydraulic bulging

The hydraulic bulging of the tee is a forming process of compensating the bulging of branch pipe by the axial direction of metal material.The process is to use special hydraulic press, with three links within the tube billet diameter equal injection liquid, through the two horizontal side of the hydraulic cylinder synchronization of the motion of tube billet, billet after squeezed smaller volume, smaller volume of liquid with the tube billet inside the tube billet and pressure, when pressure tee branch pipe bulge out to the metal material in the liquid in the cylinder and the pipe pressure under the dual role of flow along the mold cavity and the branch pipe.
