Low-temperature alloy steel pipe   has lots advantages, such as high strength, long service life, wide uses, and economical. Low-temperature alloy steel pipe is mostly rolled into plates, profiles, seamless steel pipes, etc., it is widely used in chemical industry, pipeline transportation, mining engineering and other industries that need to operate in low temperature environments. Low-temperature alloy steel pipe has a certain amount of silicon or manganese basic elements, also it can contain vanadium (V), niobium (Nb), titanium (Ti), aluminum (Al), molybdenum (Mo), nitrogen (N), and rare earth (RE) and other trace elements. In this type of steel, in addition to grade A and B steel, at least one of grade C, D and E steel should be included. Q345A, B, C, D, E are representative grades of low temperature steel, which A and B grade steel are usually called 16Mn, also known as Q345B.

The advantages of   welded pipe   equipment are: 1. Economic benefits. The noise of welded pipe equipment is small, and the use of circulating water cooling system is environmentally friendly and energy-saving. 2. Uses. Welded pipes are used more and more widely, which are suitable for agricultural and industrial production. 3. Quality. The finished welded pipe is good, the weld seam is complete with less burrs, the speed is fast, which is energy saving and cost saving. 4. Welded pipe equipment. Heterosexual pipes, square and rectangular pipes can be produced on welded pipe equipment. Because the welded pipe equipment can withstand greater bending force, which can save a lot of metal and save processing hours. 5. Environmentally friendly. The production of high-frequency welded pipe equipment has the characteristics of no pollution and low noise, and does not produce waste water or waste gas. Circulating water cooling is used in production, which is energy-saving and environme...

Seamless steel pipes   have hollow sections and are widely used as pipes for conveying fluids, such as pipes for conveying oil, natural gas, gas, water and certain solid materials. The seamless pipe has a certain corrosion resistance, but in order to prolong the service life of the seamless pipe in some extreme environments, it is necessary to remove the oxide layer on the surface of the product. The main cleaning method is pickling. After cleaning, electrolytic cleaning is required again. 1. The seamless steel pipe must wear labor protection supplies before pickling. The on-site working environment should also be checked in detail, mainly to check whether the hoisting of the steel pipe is intact, and work can only be carried out after confirming that it is intact. 2. When pickling seamless steel pipes, the pickling method is mainly hydrochloric acid pickling. Usually, the content of hydrochloric acid is preferably 18% to 20%. 3. The staff also need to know the concentration and te...

Cement mortar anti-corrosion spiral pipe   is to do the anti-corrosion of cement mortar on the inner wall of the water delivery pipeline. And Cement mortar anti-corrosion is a method to protect pipe from corrosion, which formed by a cement coating of 8-16 mm on the inner wall of the spiral pipe by a centrifuge or a pipe sprayer, and then air-dry for about 2-3 days to avoid cracks. The biggest advantage of using cement mortar for internal anti-corrosion is that it can ensure water quality and reduce the corrosion of water to the inner wall of the pipeline. Therefore, cement mortar anti-corrosion spiral pipes are suitable for high-rise building water supply, heating network heating, tap water engineering, gas transmission, and buried transmission. Also used for water pipe sewage treatment: sewage treatment discharge pipes, sewage pipes and bio-pool anti-corrosion engineering and agriculture: agricultural irrigation pipes, deep well pipes, drainage pipes and other networks.
