May 26, 20211, carbon steel pipe
The fixed oil pipeline multi-purpose carbon steel pipe, carbon steel pipe according to its manufacturing method can be divided into seamless steel pipe and welded steel pipe, seamless steel pipe is divided into hot rolled and cold drawing two, usually the carbon steel pipe is made of boiling steel, temperature range of 0~300℃, low temperature is easy to embrittlement, the steel pipe made of high quality carbon steel,The temperature applicable range is -40~450℃, using 16Mn steel, the temperature applicable range of low temperature is -40℃, high temperature can be up to 475℃.
2, oil resistant hose
Oil resistant hose is mainly used for temporary loading and unloading of oil transmission facilities or pipeline unloading of the active parts of the oil pipeline.
Oil – resistant rubber hose has oil – resistant laminated rubber hose, oil – resistant spiral hose and oil – resistant steel wire braided hose, are made of nitrile rubber.And divided into pressure, suction and suction three different situations of use, positive pressure conveying should be selected pressure hose, negative pressure conveying is selected suction hose, there may be positive and negative pressure when you need to choose suction hose.
