EV Group China supplies metal products that fully comply with these regulations, ensuring high corrosion resistance when operating under critical temperature conditions.<\/p>\n<p>The standard covers pipes with the following geometric parameters:<\/p>\n<ul>\n<li>Outside diameter: from 3.18 to 127 mm (range from 1\/8 to 5 inches).<\/li>\n<li>Wall thickness: from 0.38 to 12.70 mm (range from 0.015 to 0.500 inches).<\/li>\n<\/ul>\n<p>All requirements for dimensional tolerances are defined in specification B751. EV Group China offers custom manufacturing services for welded pipes of non-standard sizes, provided that all mechanical and chemical indicators established by this standard are met.<\/p>\n<p>In the technical documentation, values in the inch-pound system are prioritized. Metric values provided in parentheses are for reference only.
