Introduction:

SS304 stainless steel pipe belongs to the US grade stainless steel materials, domestic grades equivalent to 0Cr9Ni9 stainless steel pipe, usually 0Cr8Ni9 instead.

OD:6mm ~ 630mm

WT:0.5mm ~ 70mm

Length:6m or as customers' demand

Surface Treatment:Matte(usually used as industrial pipe) / Mirror finish(usually used as decoration pipe)

Test: For steel to withstand fluid, pressure hydraulic test should be carried out to test its quality, leakage does not occur at a predetermined pressure, wet or expansion of qualified, some steel but also do curling trials , flaring test, flattening test according to the standard or demand side.

Application:

304 stainless steel pipe is a hollow strip steel, a large number of used for conveying fluid pipe, such as oil, natural gas, water, gas, steam, etc. in addition, it will be lighter engaged in the same torsional strength. so also widely used in the manufacture of mechanical parts and engineering structures. Also used in producing all kinds of conventional weapons, the barrel, shells and so on.
