Flange is divided into threaded connection (thread connection) flange, welding flange and lap joint flange. The client is a medium-sized builder in the Philippines, s...

The scope of application of seamless tubes in production and life is getting wider and wider. The development of seamless tubes in recent years has shown a good trend. For the manufacture of seamless tubes, it is also to ensure its high-quality processing and production. I will give you some brief introductions about the production process of seamless tubes here, so that everyone can understand it. The manufacturing process of seamless steel tubes is mainly divided into two major steps: 1. Hot rolling (extruded seamless steel tube): round tube billet →heating →piercing →three-roll cross rolling, continuous rolling or extrusion →stripping →sizing (or reducing) →cooling →straightening →hydraulic test (or flaw detection) →marking →warehousing The raw material for rolling seamless pipe is round tube billet, and the round tube embryo should be cut by cutting machine to grow billets with a length of about 1 meter, and transported to the furnace by conveyor belt. Billet is fed into the furnac...

SAW pipe (Submerged Arc Welding Steel Pipe), it can be classified into longitudinal submerged arc welding steel pipe (LSAW steel pipe) and spiral submerged arc welding steel pipe (SSAW steel pipe). SAW is a manufacturing process using submerged arc welding of steel,this process produces high current density, which prevents the flux layer from losing heat quickly and concentrates in the welding region. Commonly used standard is API 5L. Submerged arc weld of high quality,high production efficiency, arc and smoke a few characteristics of submerged arc welded pipe is widely used in pressure vessels, pipe manufacturing, beams, low pressure fluid, steel works. ERW pipe (Electric Resistance Welded Steel Pipe) uses the skin effect and proximity effect of high-frequency current to heat and melt the edge of the pipe blank after the hot rolled coil is formed by a forming machine, and presses it under the action of a squeeze roller Welding to achieve production. ERW has the characteristics of high...

With the increase of project demand, more and more customers will choose Xinyue’s Elbow.

 Seamless pipe has better pressure capacity, strength is higher than ERW welded pipe. So it is widely applied in high pressure equipment, and thermal, boiler industries. Generally the welding seam of the welded steel pipe is the weak point, the quality affect overall performance. Seamless pipe vs welded steel pipe: 1. Appearance difference Seamless steel pipe used steel billet as raw material. The outer surface defects of billet cannot be eliminated by hot rolling process, it is only polished after the product finished. In the process of wall reduction, the defect can only get partially eliminated. Welded steel pipe made by hot rolled coil as raw material, the surface quality of coil is just the pipe’s surface quality, and easy to control.The surface of hot rolled coil have high quality. So Welded steel pipe surface quality is much better than seamless steel pipe. 2. Molding Process difference Seamless steel pipe can be formed one time in the rolling process. Welded steel pipe is m...
