The cold brittleness (or low temperature brittleness tendency) of the cold-drawn tube is expressed by the ductile-brittle transition temperature Tc. The TC of high-purity iron (0.01%C) is -100 ℃

Among high-alloy steels that are exposed to air, corrosive media or chemical corrosion, stainless steel has the inherent appearance characteristics and colors of electroplating and stainless steel, su

Does the cold drawn pipe need nitrogen during welding ? Nitrogen is used in the processing of cold drawn tubes and other stainless steel products, especially during welding.

The calculation formula of measuring ruler is: (outer diameter - wall thickness) * wall thickness * 0.02466 = weight of 1m precision cold drawn tube! Wuxi Qifang Steel Pipe Co., Ltd. stated that both

In the process of processing and manufacturing, attention should be paid to precision cold-drawn tubes of various sizes, and their performance advantages should be continuously enhanced in production.

Due to the good mechanical properties and excellent economic and technical value of precision cold-drawn tubes, in economically developed areas, more than 80% of the cylinders use high-precision cold-

(1) High production efficiency: the traditional method takes 154 hours to produce a cylinder with an inner diameter of 420 mm and a length of 12 meters, while the cold drawing method only takes 4 minu

Cold drawn tubes have high requirements in production and processing. Due to its high surface temperature, fast shrinkage and fast condensation, the cold-drawn tube is easily affected during the conde

Reasonable stacking of cold drawn tubes, first in first out: 1. The principle of stacking cold-drawn pipes is to stack them according to varieties

1. Before materials are put into storage, rainwater or impurities should be prevented from entering. For materials exposed to rain or pollution, different methods should be used to wipe them according

1. Keep the material warehouse clean, with unimpeded drainage and away from harmful gases or dust. Weeds and all debris should be removed from the site to keep the steel clean.

During the installation of stainless steel precision pipelines, elbows, flanges, tees, etc. are required, because some must be operated in accordance with relevant implementation
