  1, Because most of the pipe for welding, in order to improve the quality of welding, the end of the car into a groove, leaving a certain angle, with a certain edge, this requirement is also more strict, thick side, the angle of how much and deviation The scope of the provisions are provided. The surface quality and mechanical properties are basically the same as those of the tube. For easy welding, the pipe is the same as the steel of the pipe being connected.

  2, That is all the pipe fittings have to go through the surface treatment, the inner and outer surface of the oxide scale through the shot peening spray, Carbon Steel Butt Welded Forged Pipe Fitting Bend coated with anti-corrosion paint.

  3,  the requirements for the packaging for small pieces, such as exports, you need to do wooden box, about 1 cubic meter, the provisions of this box in the number of elbows can not be more than one ton, the standard allows suits, But the total weight is generally not more than 1 ton. For large pieces of y will be a single package, like 24 "must be a single package. The other is the packaging mark, mark is to indicate the size, steel, batch number, manufacturers and other trademarks.
