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 production an

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 may cause sea

  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.
