The Pipeline Joining & Fabrication Line adopts modular design, which is capable of completing automatic multiple pipe fitting-up, joining and welding fabrication job.




It integrates with roller-bed type conveying system to reduce the dependence of on-site crane equipment, which improves the production efficiency greatly.


Applicable Industries: Offshore, Petrochemical, etc.


Applicable Projects: Offshore LNG Module, LNG Purification Device , Oil & Gas Pipe Racks/PARS, Oil & Gas Transportation Pipeline





  1. Overall lifecycle production informationized management systems make QC covers each process; quality status can be recordand feedback to QC monitoring and management terminal;

CNC control medium frequency induction preheating and post-heating system can precisely control preheat and post-heat temperature (temperature accuracy of ±10°C) with high accuracy of heating and cooling temperature control, which lays the foundation of good welding quality;


Inspection area is arranged after each working step finished in the production line; next process will inspect and control the quality of upper process;

4Square wave AC + square wave AC double arc double wire submerged arc welding process can eliminate workpiece magnetic influence on welding process to increase first welding qualification rate.

Mature & high efficient automatic root pass welding technology provides high quality and efficiency foundation for Fabrication engineering.


Systematic and scientific production line process planning lays the foundation for improving production efficiency;


Complete production line logistics system realizes automation and mechanized operations of the fabrication process, which reduces labor workload to maximum rate and achieves industrialized mass production capacity;


The whole production line adopts logistics designing mode; the material transportation efficiency is more than 3 times higher than that of crane lifting mode, which reduces logistics cost in the production process;


The configuration of professional equipment is arranged specially for pipeline fitting-up & joining project, such as the high speed pipe end beveling machine, radius changeable medium frequency preheating system, mechanical welding joint fitting-up equipment, welding seam gouging machine, medium frequency heat treatment system, pipeline transferring / conveying logistic system, etc. The efficiency of professional equipment instead of labor is 5-10 times higher than traditional process efficiency.
