The basic principle of bimetal composite steel pipe: The external base pipe is responsible for the pressure and the rigid support of the pipe, and the inner liner is responsible for the corrosion resistance.
Outer base pipe can use different diameters and thickness of carbon steel pipe according to the flow and pressure requirements of the transmission medium. Hot dip galvanized steel pipe, straight seam welded pipe, spiral pipe, seamless steel pipe for low and medium pressure fluid transportation, high pressure boiler, seamless pipe steel pipe for oil cracking, line pipe, etc. The diameter can be from φ20-φ1020mm, and the wall thickness can be from 2.5-50mm.
The inner liner can use different corrosion resistant alloys depending on the chemical composition of the medium. Austenitic stainless steel 304, 304L, 316, 316L, copper-based alloys, nickel-based alloys, Hastelloy, titanium, titanium alloys, duplex stainless steels and other new high corrosion-resistant alloy materials. Liner tube wall thickness can be from 0.3-4mm depending on service life and welding process requirements.
