Product Introduction

First-class welding technology

Products Description

Double submerged arc welded pipe，the first advantage is the complete realization of automation; the second advantage, it is welded under the submerged arc, so its heat exchange and protection performance is relatively strong, welded out of the quality is relatively high; the third advantage, due to the submerged arc automatic welding in the arc buried under the flux, so it can be used in high current, welding efficiency is relatively high, recently our country is carrying out the West-East pipeline project, the pipeline is a kind of high-strength steel Recently, our country is carrying out the west-east gas pipeline project, the pipeline is a kind of high strength steel, this kind of pipeline in the factory first prefabricated into a section, and then get to the site, welding in the field, this kind of pipeline in the factory production of welding process is the use of submerged arc welding, submerged arc welding has now developed into a double-wire submerged arc welding, and multi-wire submerged arc welding, the efficiency of the further improvement.

GNEE has many years of production experience
