تصنيف المواد لخط أنابيب نقل النفط

1, الأنابيب المصنوعة من الصلب الكربوني

The fixed oil pipeline multi-purpose carbon steel pipe, يمكن تقسيم أنابيب الصلب الكربوني وفقًا لطريقة التصنيع إلى أنابيب فولاذية غير ملحومة وأنابيب فولاذية ملحومة, يتم تقسيم الأنابيب الفولاذية غير الملحومة إلى اثنين من الأنابيب المدلفنة على الساخن والباردة, 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.

زيت – resistant rubber hose has oil – resistant laminated rubber hose, زيت – 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.
