A weld neck flange is a type of steel flange designed to transfer stresses to the pipe to reduce high stress concentrations at the base of the flange. Compared with other types,weld neck flanges are know for their tapered hub and gentle transition from flange thickness to pipe wall thickness. They are deformation-resistant, and are normally used for high pressure,high or low temperature conditions.
When we set up our stockholding division ‘Stock Services’ in 2008 we begun with the goal of becoming one of the top three distributors of stainless steel SEAMLESS fittings, buttweld pipe fittings, forged pipe fittings & pipe flanges in India. In 2010 we’ve got our own manufacturing plant in India and Ras Al Khaimah & since then we have developed our range further to include Weld Neck Flanges, WNRF Flanges, ANSI B16.5 Weld Neck Flanges, ASME B.16.5 Weld Neck Flanges Pipe Flanges. Our range of seamless pipe fittings and pipe flanges are held in dual certified grades 304/304L and 316/316L, and you can find accurate & best price here on our website.
We can now provide fittings and flanges in one package, and with our experience in distribution, can ship Stainless Steel Weld Neck Flanges, ASTM B.16.5 Weld Neck Flanges, Carbon Steel Weld Neck Flanges all over the world on quick lead times.
Below are our available Weld Neck Flanges that will meet your project needs. We will help you put together your entire project and ship it to your closest port. We ship globally!
