GB/T 13793 Galvanized Welded Steel Pipe

Introduction

GB/T 13793 welded steel pipe is a type of steel pipe with a straight weld seam. It is made by electric resistance welded process. In order to improve its corrosion resistance and service life. GB/T 13793 welded steel pipe should be hot dipped galvanized on the inner and outer surfaces before delivery. The zinc layer can effectively prevent the contact between the steel pipe and corrosive media in air. We can provide galvanized welded steel pipes that the zinc thickness range is 300 g/m2 to 500 g/m2. We will carefully check all galvanized steel pipes before shipment to ensure that the inner and outer surfaces of steel pipes are fully galvanized.
