Ss201 304 316 Stainless Steel Round Pipes Tube for Decoration

      This 316L stainless steel round tubing is suitable for transport of fluids and gases in chloride environments. The tubing is seamless for a smoother interior flow and greater burst strength than welded tubing. It has is alloyed with molybdenum and has higher resistance to pitting and crevice corrosion in chloride environments than 304 stainless steel. The tubing is annealed to restore formability for bending or flaring the tubing and has an operating temperature range of -325 to +1,500 degrees F. This seamless round tubing meets American Society for Testing and Materials (ASTM) A269 specifications for quality assurance and is suitable for use in applications such as food and beverage preparation equipment in wash down environments.

    Metal tubing, also called fractional tubing, is used to transfer liquids, air, or solids, and it is characterized by a round shape and a hollow center. Metal tubing is commonly made with various grades of austenitic stainless steel, aluminum, copper, brass, and titanium materials and their alloys. Construction types include seamless, welded, or welded and drawn. Seamless tubing has no seam or weld point, which enables it to better withstand high pressure and resist corrosion. Welded tubing, made by rolling and welding metal sheet stock, is weaker than and not as rounded as seamless tubing, but it has a more consistent wall thickness for tighter wall tolerances. Welded and drawn tubing, also known as "drawn over mandrel" (DOM), is typically welded tubing that is drawn through a die and over a mandrel to create a smooth inner diameter, which gives the tubing comparable corrosion resistance to seamless tubing while still offering welded tubing's tighter wall tolerances. Compression, vacuum, sanitary, and flared fittings connect tubing or redirect flow in a fluid handling system. Metal tubing is used in HVAC and plumbing systems and for applications in the aerospace, automotive, chemical processing, food and beverage, manufacturing, and medical industries.

  1. What  is your major market?

    90% of our tubes export to Europe and Latin America, like Russia,Poland, Lithuania, UK,Columbia,Canada,etc..

 2. What is your location?

    Our headquater is in capital city, Beijing, and our factories are located in Foshan City which is a famous stainless steel production base. 

 3.What's the annual output?

   Vinmay produce more than 25000 tons stainless steel tubes in a year.

4. What is your welding method?

    All of  our tubes are welded by tig welding methods and fully welding and smoonth inner welding, without blisters, leak welding or black line. 

5. How do you control the quality during the polishing  process?

   1)As for the mirror polish square/rectangular tube , we will polish it as least four times)

   2)During the polishing processing, we set a special sanding wheel to polish the welding part.

   3)To avoid scratches,after polishing,the tubes will be lay out on a steel crate then we could lift the whole steel crate instead of the tube.

  4)On the other hand, we use the gunny bags to protect the tube's surface when the tube laying-out.

6. How do you inspect the tubes?

The Quality inspectors inspect the tubes during each production processes from raw material,tube welding,polishing,packaging.

1)  Before the production of each machine, we will have the first checked and record the data.

2). During the production, our inspector and engineer have been carefully moniting and we record the        data every two hours.
