spiral dust collection pipe Spiral welded pipe: it is to roll the low carbon carbon structural steel or low alloy structural steel strip into tube billet according to certain spiral Angle (called forming Angle), and then weld the tube seam to make it. It can use narrow strip steel to produce large diameter steel pipe.Its specification is indicated by the outer diameter * wall thickness, and the welded pipe shall ensure that the water pressure test, tensile strength and cold bending performance of the weld meet the requirements.

Spiral Dust Collection Pipe
Now the diameter of spiral welded steel pipe can reach 3620mm.Manufacturing spiral steel pipe in our country in the majority with diameter of 1.8 meters the following, the vast majority of 1220 for the following pipe diameter, domestic individual manufacturer can be up to 2500 mm, very few manufacturers of up to 3200 mm, the past into a search engine to find how wide is the largest diameter, zhengzhou zhongyuan steel pipe technology co., LTD., the production of spiral welded pipe diameter is 3620 mm, from now on, in the domestic large diameter spiral welded pipe diameter is 3620 mm.Nowadays, it's all over the place in search engines.
Industry advantageThe spiral pipe is formed by bending hot rolled strip steel in spiral shape and welding the inner seam and outer seam by submerged arc automatic welding.It can be widely used in the production of large diameter spiral tubes for the following reasons:1) as long as the forming Angle is changed, spiral pipes of various diameters can be produced with strip steel of the same width;2) due to continuous bending, the length of the spiral tube is not limited;3) the spiral shape of the welding seam is evenly distributed on the circumference of the entire spiral pipe, so the size accuracy of the spiral pipe is high, and the strength is also high;4) easy to change the size, suitable for the production of small batch and multiple varieties of spiral pipes.
