The quality of different-diameter tube high-pressure pipe fittings should conform to the current national standard “steel butt welded Seamless pipe” GB/t 12459-2005, the roundness of the reducer should not be greater than the corresponding end diameter of 1%, and allow the deviation of the ±3mm; the permissible deviation of the size of the reducer shall conform to table 4.2.
There are many kinds of pipe fittings of high pressure reducer, but what are the main types? In daily life is often able to contact, the use of pipe fittings is very large, pipe types, a wide range. Pipe is the the necessary raw materials, but the processing method of the pipe is many, as long as it is mechanical processing method, it can be applied. Pipe fittings have two outstanding advantages: the first is to replace part of the machining products, and than machining parts, castings, forging structural parts light weight, saving materials; Second, compared to mechanical processing products to save the process, work hours, reduce the cost of the workpiece.
we have our own pipe fitting factory since 1998 ,which covers 100 acres. In 1998, we invested and set up a new flange factory. Up to now, we have a complete production system, and become a professional and competitive group in this field.
