Product Detail

Chrome plated steel tube are coated with a layer of metal on the surface of the steel pipe metal through electroplating. The most important purpose of chromium plated steel pipes is to protect them. Chromium plated steel pipes have good chemical stability and do not react in alkali, sulfides, and most organic acids. Chromium plated steel pipes are soluble in hydrochloride acid (such as) and heat. Secondly, chromium plating has good heat resistance, and chromium plated steel pipes only oxidize and discolor when the temperature is greater than 500 degrees Celsius. And his friction coefficient, especially dry friction coefficient, is among all metals, and chrome plated steel pipes have excellent wear resistance. In the visible light range, the reflection ability of chromium is about 65%, between silver (88%) and nickel (55%). Chromium does not change color, and chrome plated steel pipes can maintain their reflection ability for a long time when used, which is better than silver and nickel.

Commonly used structural chromium plated steel pipes are mostly used for seamless steel pipes in general and mechanical structures; Some are used for transporting fluid chrome plated steel pipes, primarily suitable for transporting fluids such as water, oil, gas, etc. Stainless steel capillary tubes are used in the design of low and medium pressure boilers, which are mostly used to manufacture Superheated steam tubes and boiling water tubes for low and medium pressure boilers of various organizations, and carbon structural steel hot rolled and cold drawn seamless steel tubes for Superheated steam tubes, smoke tubes, small smoke tubes and arch brick tubes for locomotive boilers; In high-pressure boilers, chromium plated steel pipes are mostly used to manufacture seamless carbon steel and stainless steel hot steel pipes for the heating surface of high-pressure and above pressure water tube boilers

In the application of fertilizer equipment, there are generally requirements for the temperature and pressure of Douay operation; In petroleum cracking, it is mostly suitable for seamless steel pipes, heat ex-changers, and pipelines in oil refining plants; In addition, the use of stainless steel capillaries plays an important role in many fields such as geological drilling, diamond core drilling, and the use of oil drilling pipes.
