TISCO Welding ERW Gi Steel Pipe Use For Constraction Galvanized steel pipe is a welded steel pipe with a hot-dip
galvanized or electro-galvanized layer on the surface. Galvanizing
can increase the corrosion resistance of steel pipes and prolong
the service life. Galvanized pipes are widely used. In addition to
being used as pipeline pipes for general low-pressure fluids such
as water, gas, and oil, they are also used as oil well pipes and
oil pipes in the petroleum industry, especially in offshore oil
fields, as well as oil heaters and condensers in chemical coking
equipment. Pipes for coolers, coal distillation washing oil
exchangers, and pipes for trestle piles and supporting frames of
mine tunnels, etc. Surface | Galvanized (200-600g/m2 usual,can be request by customer) | Material | Q195,Q215,Q235 | MOQ | 5 tons for normal size and material | WT | 1.5-20mm | Payment terms | TT deposit +BL copy / LC or 100% LC at sight | Trade terms | FOB,C&F,CIF,EXW | Length | fixed or random,as customer request. | End Treatment | Plain(can be threaded,punch,shrink,extension... ) | Lead time | within 7 days from stock with 6m length (stock pipe with our
