Product Details

spiral pipe welding Spiral welded pipe plays an important role in gas transportation.With several major pipeline engineering planning and construction at home and abroad, the large deformation of pipeline steel, high strength thick low temperature level roasted bend and pipe fittings for high-value-added products, showing good market competition ability and large market demand, the domestic enterprises in the development of this series of products progress slowly, should be developed as soon as possible is suitable for the industrial application of high added value and large deformation of pipeline steel, roasted bend pipe steel, pipe yard with low temperature pipes with steel, X100 straight seam submerged arc welding pipe, spiral seam submerged arc welding pipe and roasted curved spiral welded pipe.

spiral pipe welding

Anticorrosive spiral pipe welding technologySince the individual quality of spiral welded pipe is relatively large, it must be stacked outdoors, but it is hard to avoid being exposed to the sun and rain, so the problem of rust has been troubling the storage time and condition of spiral welded pipe.Therefore, it is necessary for us to provide a comprehensive solution to the rust prevention knowledge of spiral welded pipes.

Mainly USES the steel wire brush and other tools to polish the steel surface, spiral welding pipe cleaning and preheating can remove loose or warped oxide, rust, welding slag and so on.Manual tool derusting can reach Sa2 level, power tool derusting can reach Sa3 level, if the steel surface adheres to a strong scale, tool derusting effect is not ideal, not up to the anti-corrosion construction requirements of anchor depth

Pickling USES solvent and emulsion to clean the surface of welded steel tube (welded tube) used for low-pressure fluid transportation, so as to remove oil, grease, dust, lubricant and similar organic matters. However, it cannot remove rust, scale and flux on the surface of steel, so it is only used as an auxiliary means in anti-corrosion production.

Welds of the third kind: welds of auxiliary members with small force and no stopping of power generation or water supply during repair.1. Before welding, clean the oil, paint, scale, rust and burr on the groove and its inner surface not less than 10mm, and avoid cracks, interlayer and other defects.2. When the butt welding line of pipes or fittings is matched, the inner wall shall be flush, and the amount of wrong side of the inner wall shall not exceed 10% of the thickness of the pipe wall, and shall not be greater than 2mm;3. The electrode shall be dried according to regulations before use and shall be kept dry during use.Remove the oil and rust on the welding wire before use.Welding rod, wire and flux used for all kinds of pipeline welds can be selected according to the following table.
