6, for pipe fixed pipe: clasp, drag hook, rings, brackets, brackets, pipe cards, etc.

Fittings are generally used for pipes with DN ≥ 50mm, widely used in flammable, combustible media, and other medium pipes with high temperature and pressure parameters.

Pipe wall thickness level with pipe table number shows that the commonly used pipe table number Sch40, Sch80, the choice of pipe fittings, pipe fittings should be connected with the pipe of the same pipe number, that is, pipe and pipe strength (rather than equal wall thickness) , Only the wall thickness of the pipe end is the same as the wall thickness of the tube.
