Straight seam welded steel pipe widely used in industrial production is quite special compared with round steel pipe that pipe shape is seen most often in all walks of life.Besides,quality requirements for straight seam welded steel pipe stay at a high level.For example,gas company whose priority demand is pipe quality will purchase straight seam welded steel pipe for transporting coal gas.Some results are removed in response to a notice of local law requirement.For more information,please see here.Production Standard of High Frequency Straight SeamThe high-frequency straight seam welded pipe is generally produced with a small diameter,and the outer diameter is generally less than 660mm or 26 inches.Its characteristics are fast welding speed,for example,for steel pipes with an outer diameter of less than 1 inch,the maximum welding speed can reach 200 meters / minute.

Porosity and Crack of Spiral Welded Pipe

However,compared with the same length of straight seam pipe,the weld length of 30 to 100%,and lower production rate.Therefore,smaller diameter pipe is mostly a straight seam welded,large diameter spiral welded pipe is mostly used.Pipe Inspection,Testing Marking Requirements to Ensure The carbon steel pipe standards require only that the finished pipe shall be reasonably straight.ASTM A312M (in ASTM A999M) requires a welded stainless steel pipe to be straight to within 3.2 mm over 3.0 m lengths.Generally,the thumb rule is that 1 mm per meter is acceptable.PPT High Frequency Welding Pipe line - DTZ25This kind of machine taking the steel strip with certain width as raw material,to produce steel pipes according to requested size by cold roller forming and H.F.welding method.High Frequency welded tube mill is mainly used to produce tubes for heat exchanger,refrigerator,frame for car,bicycle,fitness equipment,furniture,cooling machine,petrol transmission,construction industry,and

Identification Method of Seamless Steel Pipe and Welded

In the process of distinguishing welded steel pipe from seamless steel pipe by corrosion method,the weld seam of welded steel pipe should be polished.After polishing,the polished trace should be seen.Then the end face should be polished with sandpaper at the weld seam,and the end face should be treated with 5% nitric acid alcohol solution.Identification Method of Seamless Steel Pipe and Welded In the process of distinguishing welded steel pipe from seamless steel pipe by corrosion method,the weld seam of welded steel pipe should be polished.After polishing,the polished trace should be seen.Then the end face should be polished with sandpaper at the weld seam,and the end face should be treated with 5% nitric acid alcohol solution.How to inspect straight seam welded steel pipe Straight seam welded steel pipe widely used in industrial production is quite special compared with round steel pipe that pipe shape is seen most often in all walks of life.Besides,quality requirements for straight seam welded steel pipe stay at a high level.For example,gas company whose priority demand is pipe quality will purchase straight seam welded steel pipe for transporting coal gas.
