Quality leading manufacturer and exporter of pipe bends and elbows Zizi supplies 90 Degree 5D Bend for Pakistan, they are made of high quality alloy steel Grade 91 and their price is attractive.
Steel pipe bend is very similar with elbows. They have same diameter range, wall thickness and end form. What’s the difference between them? It’s the radius. Elbows have long radius (R=1.5D) and short radius ( R=1D) types only, while bends radius usually are larger than 1.5D, such as 3D, 4D, 5D, 6D, 7D, 8D, 9D and 10D.
