GB/T 33971-2017Hot rolled wide strips for coal slurry line pipe (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

1 Scope

This standard specifies the coal slurry pipe with a wide range of hot rolled steel strip and the classification and grades that method, order content, size, outside Shape, weight, technical requirements, test methods, inspection rules, packaging, marking and quality certificate.

This standard applies to coal slurry transmission LSAW steel and straight seam resistance welded steel pipe with a thickness of 6mm ~ 22mm wide strip And its shear plate, also applies to other slurry pipes with similar requirements Hot-rolled wide strip and its shear plate (hereinafter referred to as the strip and Steel plate).
