A671 CC70 Class 32 Pipe manufacturer in india guaranteed best price in india
ASTM A671 CC70 belongs to a killed carbon steel specification with pipes made under electric fusion welding by welding the edges of the pressure grade plates together. Multi Metals (India) is a leading manufacturer and supplier of these ASTM A671 CC70 pipe products in large scale. The material can be welded with conventional methods and EFW, submerged electric arc and oxyacetylene gas welding.
However, to weld with high temperature procedures, the ASTM A671 Grade CC70 pipe has to be preheated and post weld heat treated after welding. The pipes come in diameters ranging from 16 inches to 100 inches with wall thicknesses up to 250mm. The A671 CC70 Cl22 is used in petroleum, petrochemical and oil and gas industries primarily with lengths ranging up to 13 m. The lengths vary as single random, double random and cut to length sizes.
There are also different schedules to the A671 CC70 EFW Pipe grade ranging from sch20 to XXS and heavier upon request from customer. The pipes can also be coated with different material based on the application requirement. There are epoxy coating, color painting and 3LPE coating available for the A671 CC70 pipes. Please feel free to contact us for more product specifications, details and prices of the different pipes in the A671 Gr.Cc 70 Cl22 class.
