Home; Products. Galvanized Steel Pipe; Stainless Steel Pipe; Seamless Steel Pipe; Welded Steel Pipe; Square Steel Pipe; Spiral Steel Pipe; Steel Square Bar; Steel Flat BarHow to Guarantee the Product Quality of ERW High The advantage of this processing technology of ERW high-frequency welded pipe is that there is a heat treatment process after welding, which eliminates the residual stress of the weld and heat-affected zone, refines the grain, and the heat-affected zone of the weld is small, and the heating speed is fast, which can greatly increase the welding speed. And the quality of the welding seam, and the strip steel that How to choose high quality straight seam welded pipeHow to choose high quality straight seam welded pipe . When choosing a straight seam steel pipe, we must first pay attention to the material. When we inspect the goods, we must first determine whether the material is qualified. The second is to see if the wall thickness of the straight seam steel pipe reaches the required wall thickness.Pipe Manufacturing Process / Methods for Seamless & Welded A welded pipe can be manufactured in large sizes without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric ManufacturingHigh quality welded steel pipe
Dimension tolerances of Stainless Steel precision piping are usually according to customer's requirements, and mostly the precision tolerances are EN ISO 1127 D4/T4, EN 10305-1, and Outside Diameter 0.05 mm, Wall Thickness 0.05 mm. SS precision seamless tubes can also be machined by honing or SRB process to produce stainless steel honed tubes. In this case, the ID tolerance could be Process pipe welding Filler metal options to improve ManufacturingHigh quality welded steel pipeAdvanced technologies like modified short-circuit GMAW or pulsed gas metal arc welding (GMAW-P), as well as conventional GMAW and flux-cored arc welding (FCAW), can help speed production, ease training, and produce high-quality welds in process pipe applications. With this conversion, however, comes the question of filler metal selection.QUALITY CONTROL - Steel Pipe and Fittings SupplierSometimes, MS pipe bundles are wrapped by fabric layer to protect surface coating. Each bundle of pipes is tightened by 8 steel straps, with 3 straps at each end and 2 straps in the middle. Then 2 nylon slings are banded for crane loading. Pipes under OD508mm are packed by individual bundle.Quality Control - U.S. PipeThe purpose of this section is to display the general parameters and guidelines for the quality control of products manufactured on a day to day basis at the manufacturing facilities of U.S. Pipe Fabrication. It is the intent of U.S. Pipe Fabrication to furnish products of the highest quality, using the best materials and workmanship available.

Steel pipe is the long, cylindrical hollow metal pipe that is used for a variety of purposes which can be classified into seamless pipe and welded pipe by their forming method. Metal pipe is widely used to transport flowing medium like oil, gas, or water over long distance, or in common household appliances and structural requirements like hand rails and pipe bollards, it is also applied in a ManufacturingHigh quality welded steel pipeThe difference between seamless pipe and seamed pipeSep 12, 2020Welded steel pipes need to be welded after rolling, generally with spiral welding and straight welding. The performance seamless tube is better, and of course the price is higher.
