SAW (LSAW/SAWL) STEEL PIPE, WATER PIPELINE
By carrying out standard Non-Destructive Detections on our LSAW pipes, we ensure that our pipes serve our customers well. Our LSAW steel pipes are ideal pipes for large-scale pipeline engineering, petroleum, water or natural gas transportation and urban pipe network construction and piling.
