Electrical Resistance Welding, ERW Steel Pipes are manufactured by cold forming of steel coil into a round cylindrical shape. ERW Pipes was done with the low frequency A.C. current to heat the edges at first. Now high frequency A.C. instead of the low frequency process current to produce a higher quality weld. ERW steel pipes are manufactured with low frequency or high frequency electrical resistance. ERW Steel Pipes are round tubes welded from steel plates with longitudinal welds. It is used to transport gas and liquid objects such as oil and natural gas, and can meet various high and low pressure requirements. ERW steel pipes are widely used in fencing, line pipe, scaffolding etc. ERW steel pipes are produced in various diameters, wall thickness, finish and grades. Main applications ● ERW Pipes used in Water pipelines ● Agriculture & irrigation (Water mains, industrial water pipe lines, plant piping, deep tube-wells & casing pipes, sewerage piping) ● Gas pipe lines ● LPG and other non-toxic gas linesThe packaging method for steel pipes involves cleaning, grouping, wrapping, bundling, securing, labeling, palletizing (if necessary), containerization, stowing, sealing, transportation, and unpacking. Different kinds of steel pipes and fittings with different packing methods. This comprehensive process ensures that the steel pipes shipping and arrive at their destination in optimal condition, ready for their intended use.
