On the one hand, it is necessary to check the quality and installation of the cylinder, including whether there is any leakage; whether the bolts of the installation and assembly parts are loose or no

1. Make the cold drawn steel pipe structure and composition uniform, which is especially important for raw materials, because the rolling temperature and cooling rate of each section of hot rolled pip

The cutting of the honing pipe can be divided into the following stages:

Honing tube: The tube milled out with the honing machine has a straightness and a slightly lower finish. The tube is rolled, the finish is high, and the straightness is better. Both the honed pipe and

1. Manufacturing method

High-precision cold-drawn tubes are one type of steel pipe, that is, one classified according to the production process, which is different from the hot-rolled (expanded) pipe. It is formed by multi-p

1. Material selection: Select the metal bar of suitable size as the raw material bar for processing the honing pipe;

Method for removing internal oxide layer of small hole after quenching of rolling tube

Advantages of rolling tube

Some considerations for rolling tube rolling

The stainless steel honing pipe is made of seamless steel pipe. Because the inner and outer walls of the steel pipe have no oxidation layer, high pressure and no leakage, high smoothness, no deformati

In the detachment cutting stage of the honing pipe processing, since the hole wall is rough at the beginning of the constant pressure honing, the contact area between the oil stone and the hole wall i
