15crmo Galvanized Round Pipe


Implementation Standards


GB/T3091-2015 low pressure fluid transport welded pipe, GB/T13793-2008 straight welded pipe, GB/T21835-2008 welded pipe size and unit length weight


Applicable Scope

The surface of the galvanized steel pipe has a hot dipped or galvanized layer of welded pipe. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life. The use of galvanized pipe is very wide, except for water, gas, oil and other general low pressure fluid pipeline, is used in petroleum industry especially offshore oil well pipe and oil pipe, chemical coking equipment oil heater, cooler, oil pipe exchanger for coal distillation, and support piles, Zhanqiao mine tunnel the tubes.
