Fluid pipe is a hollow section, from the beginning to the end no weld steel pipe. With steel pipe manufacturing annular parts, can improve material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, at present has been widely made from steel pipe. Steel pipe or all kinds of conventional weapons indispensable materials, gun, gun barrel to steel pipe manufacturing. Steel pipe according to the cross-sectional area in the shape of different can be divided into circular tube and special pipe. Due to the equal conditions, the circumference circle area is the largest, with circular tube can deliver more fluid.
A, fluid pipe manufacturing methods
(1) general boiler tube temperature under 450 , the domestic pipe mainly use 10, 20 carbon steel hot rolled or cold drawn tube manufacture.
(2) high pressure boiler tubes are often in high temperature and high pressure conditions, when using the pipe under the action of high temperature flue gas and water vapor and fluid exchange oxidation and corrosion. Requirements of steel pipe with high rupture strength, high oxidation corrosion resistance, and have good organizational stability.
Second, the fluid pipe USES
(1) general boiler tube is mainly used to produce water wall tube, water pipe, superheated steam tube, locomotive boiler superheated steam pipe, large and small pipe and tube arch brick, etc.
(2) high pressure boiler tube is mainly used to manufacture high-pressure and ultrahigh-pressure boiler superheater tubes, reheater tube, airway, such as main steam pipe.
But, pipe also has some limitations, such as in the plane bending condition, the pipe is not square, rectangular tube bending strength is big, some agricultural machinery and skeleton, rectangular tube, steel wood furniture is commonly used. According to the different USES also needs to have other cross section shape of profiled steel pipe.
The third, the difference between the pipe and fluid structure
Low pressure fluid conveying in welded steel pipe standards of GB/T3091-2001, the general structure with seamless steel tube standards GB/T8162-1999, fluid with seamless steel tube transmission standards GB/T8163-1999.
Detail can see the standard, fluid can do structure pipe, structure pipe can't be a fluid. The surface of the fluid tube is better.
Hunan great steel pipe co.,ltd will be your best supplier of fluid pipe and structure pipe.
Difference of PSL1 and PSL2(API 5L)
The API 5L has two standards, PSL1 and PSL2, which are very different from each other. I'll talk more about the differences between PSL1 and PSL2.
Production Process of Pipe Fitting
There are many kinds of processing methods for pipe fittings.
The Future of Steel Pipe Development
The future of steel pipe development is looking promising, according to expert analysis and data. The price of carbon steel pipe is predicted to bounce back this year, with China leading the way in increasing steel consumption demands. This is due to a series of government initiatives aimed at stimulating domestic demand, including the construction of affordable housing and infrastructure projects. The demand for structural steel pipe is also on the rise, thanks to state investment in housing and engineering projects. With private investment projects also gaining popularity, the steel pipe market is set to thrive in 2017.
