stainless steel carbon steel tube

Alloy steel pipe is a kind of alloy seamless steel pipe; it includes alloy structure seamless pipe and high-pressure heat- resistant alloy tube. It main distinguished alloy pipe production standards and industry, to be annealed quenched and tempered alloy tube change its mechanical properties and achieve the desired processing conditions. Its performance is higher than the seamless steel tubes; the chemical composition of the alloy tube containing Cr is more, high temperature, low temperature and corrosion-resistant properties. Carbon seamless pipe does not contain the alloy composition or alloy composition is very small, alloy pipe is widely used in the petroleum, aerospace, chemical, electric power, boilers, military and other industries, because of the mechanical properties of the alloy tube is more changes and good adjustment.

Alloy tube is mainly used for low and medium pressure boiler (working pressure is generally not more than 5.88Mpa, working temperature under 450 ℃) of heating surface tubes; for high-pressure boilers (above 9.8Mpa working pressure in general, the working temperature of 450 ℃ ~ 650 between ℃) of heating surface tubes, economizer, superheater, reheater, petrochemical industrial pipe.

Advantages:

100% recyclable, environmental-friendly, energy-saving, resource conservation national strategy, the national policy encourages the expansion of high-pressure alloy pipe applications. Currently the proportion of the total account of our alloy steel pipe consumption is only half to the developed countriesthe, the use area of alloy tube provides a broader space for the development of the industry. According to China Association of alloy steel pipe branch expert groups, the average annual growth of China's future demand will be up to 10-12%. Alloy tube includes large diameter alloy tube, thick-walled alloy tube, high pressure alloy pipe, P91 alloy pipe and seamless steel pipe.

Features:

1, high-pressure alloy pipe: this tube can sustain under pressure, the use of this pipe to transport liquid, gas, it has more types, there are steel, brass, stainless steel tubes.
Applications: It has a hollow cross section, mainly used as pipes conveying fluids, such as transportation of oil, gas, coal gas, water and some solid materials, pipes and so on.
2, seamless: a hollow cross-section, no seams around the long steel bar. It is made of Steel ingot or solid perforate through the capillary tube, and then made by the hot-rolled, cold-rolled.
