Allowed wall thickness tolerance

Level Wall tolerance allowed
D1 +-1.5%,Min +-0.75mm
D2 +-1.0%,Min +-0.50mm
D3 +-0.75%,Min +-0.30mm
D4 +-0.50%,Min +-0.10mm

Calculating formula for weight(KG/M)

(Outdais meter-wall thickness)×wall thickness}×0.02491=KG/M


304 stainless steel decoration pipe was widely used in stainless steel anti-theft window, stainless steel railings, stainless steel stair railing, interior design, etc.
