福建三明化工机械厂生产的高压三通、四通、五通管件,过去是锻制的。由于考虑到锻件加工难度大、加工余量多、生产周期长、成本高,故采用了焊接高压管件,从而大大提高了生产率,降低了产品成本。高压管件的性能及规格管件的工作压力150～320公斤/厘米~2;工作温度-30～+200℃;工作介质无强腐蚀性。管件规格有等径和异径的三通、四通、 Fujian Sanming Chemical Machinery Factory production of high-pressure tee, Stone, five-pass pipe, the past is forged. Due to the difficulty of forging machining, machining allowance, long production cycle, high cost, so the use of welded high-pressure pipe, thereby greatly improving productivity and reduce product costs. Performance and specifications of high-pressure pipe fittings Working pressure 150 ~ 320 kg / cm ~ 2; working temperature -30 ~ +200 ℃; working medium no corrosive. Pipe fittings have the same diameter and reducing the three links, Stone,
