Large scale factory production
The production process of titanium welded pipe is as follows:
Titanium strip coil longitudinal shear forming welding internal leveling (internal weld treatment) - shaping sizing heat treatment (online bright annealing) - straightening - eddy current, ultrasonic flaw detection - Gas tightness testing - Sizing - Finished welded pipes.
GNEE has a complete set of production process, which greatly improves the efficiency of the products. The treatment of titanium welded pipe welds has always been a thorny issue in the industry. Through several years of exploration and practice, GNEE has successfully solved this industry problem, which is to realize the internal and external flattening of straight-seam titanium welded pipes. GNEE's titanium welded pipes have the same appearance as seamless titanium pipes. The performance parameters are close to and meet the requirements of seamless titanium tubes, which can be used in tube heat exchanger, coil heat exchanger, serpentine tube heat exchanger, condenser, evaporator and pipeline, nuclear power, chemical industry, papermaking, water treatment, electric heating and so on.
