1. According to the size of the pipe
1, the ends of the ends of the equal diameter three links are all the same size.

Two. Divided by material:
Carbon steel, cast steel, alloy steel, stainless steel, copper, plastic, Aluminum Alloy, argon Ge Lek, PVC etc..
Three. Dividing by making methods
Top making, pressing, forging, casting, etc.
Four. Division of manufacturing standards
The national standard, the electric standard, the standard, the water mark, the American Standard, the German standard, the Japanese standard, the Russian standard and so on, as follows: GB/T12459-2005, GB/T13401-2005, ASME B16.9, SH3408, SH3409-96, SH3410-96, HG/T21635, DL/T 695, SY/T 0510, DIN 2615.
