16Mn low alloy pipe   is: 16Mn is called low alloy high strength structural steel, its carbon content is 0.1%-0.25%, and the main alloying elements manganese, silicon, vanadium, niobium and titanium, but the total alloy content is <3%. According to the strength, it is divided into 4 level: 300, 350, 400 and 450MPa. 16Mn alloy pipe standard: GB/T8163-2008 (for conveying fluid) GB6479-2000 (seamless steel pipe for high-pressure fertilizer equipment) Alloy pipes and seamless pipes has the same charactor but different. Alloy pipes are defined by steel pipes according to the production materials, as the name implies, they are pipes made of alloys, while seamless pipes are defined by steel pipes according to the production process (seamless). Changsha Xiangjia Metal Materical Co., Ltd.  as steel division of  ADTO Group , we have over 20 years of piping materials making experience and insight into Oil & Gas, Water, Mining, Marine and infrastructure and specializing in the...

Pickling one of procedure during processing   seamless pipe   in factory, it is an indispensable part of most steel pipes, but after pickling seamless steel pipe, it is require water washing. Tips when washing seamless pipe: 1. It needs to be carried out in a flowing clear water tank to avoid pollution when wash the seamless pipe. And the seamless steel tube needs to be completely immersed in water. At this time, the sling should be loosened and lifted up and down three times or four times. 2. When the seamless pipe is washed with water, it is necessary to clean the water in the steel pipe to avoid corrosion and oxidation.  3. When the seamless pipe is washed with water, it should be noted that it cannot cross the pickling tank to avoid accidents, slipping or falling into the acid tank and being corroded by residual hydrochloric acid. 4. When the seamless pipe is washed with water, the iron salt content standard must be controlled, and it cannot exceed the standard, which...

  Reducer   is a kind of pipe fitting used for pipe diameter reduction. The forming process is reducing diameter pressing, expanding diameter pressing or reducing diameter plus expanding diameter pressing, and stamping forming. So when will the reducer be used? Let's take a look; 1. When the flow rate changed in the pipeline, such as increasing or decreasing, which required a reducer. 2. At the inlet of the pump, in order to protect pipe against cavitation, it is necessary to use reducer. 3. At the joints with instruments, such as flowmeters and regulating valves, in order to cooperate with the joints of the instruments, which required a reducer.

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.
