Seamless steel pipes   play a significant role in the construction of various low and medium pressure boiler tube. They are utilized to manufacture essential components such as superheated steam pipes, boiling water pipes, water-cooled wall pipes, and large or small smoke pipes. For locomotive boiler tube, arch brick pipes are also crafted from seamless steel. The manufacturing of these boiler tubes predominantly employs high-quality carbon structural steel, primarily utilizing steel grades No. 10 and No. 20. Beyond ensuring the right chemical composition and mechanical properties, several rigorous tests are mandated. These tests include hydrostatic tests, curling, flaring, and flattening to assess the integrity and durability of the pipes. It is important to note that seamless steel pipes can be categorized into two distinct types: hot-rolled and cold-rolled (also known as dialed) products. Hot-rolled seamless steel pipes are delivered in a hot-rolled state, whereas their cold-rol...

The material and steel grade of   high-pressure boiler tubes   have strict requirements. They are designed to work under high temperature and high pressure conditions. A large amount of water vapor will be produced in the high temperature working environment, which can cause corrosion of the steel pipes. That require the steel used in high-pressure boiler tubes to have good corrosion resistance and structural stability. High-pressure boiler tubes are used to make superheater tubes, reheater tubes, air ducts, and main steam pipes for high-pressure and ultra-high-pressure boilers. The low and medium pressure boiler tubes are executed according to national standard 3087, while the high-pressure boiler tubes are executed according to national standard 5310. The outer diameter of the hot-rolled tubes for high-pressure boiler tubes usually ranges from 22mm to 530mm, with varying wall thicknesses of 20mm to 70mm. The outer diameter of the cold-drawn tubes ranges from 10mm to 108mm, ...

High-pressure boiler tubes   are used in a high-temperature and high-pressure environment, so the material selection is strict and its process is similar to the ordinarty seamless pipe. They are widely used as boiler superheater, gas duct, steam pipe, etc. The materials of high-pressure boiler tubes is 20G carbon steel and high-pressure alloy boiler tubes. Corresponding materials can be selected according to the working environments. National standard of boiler tube is GB/T3087-2008 low and medium pressure boiler tubes and GB/T5310-2008 high pressure boiler tubes. Changsha Xiangjia Metal Materical Co., Ltd.  the Steel Pipe Division of ADTO GROUP, is one of the leading manufacturers of steel products in China. We specializes in manufacturing all kinds of steel pipe in various grades and sizes.
