By Type
The UK LSAW pipe market is segmented into UOE, JCOE, and others. UOE pipes—formed by pressing into a "U," then an "O," and then expanded—are widely used due to their superior roundness and pressure resistance. JCOE pipes are favored in mid- to large-diameter applications owing to their simplified forming process and cost-efficiency. Product choice depends on structural requirements, cost sensitivity, and specific end-use.
UOE Pipes: High dimensional accuracy and pressure endurance.
JCOE Pipes: Economical and suited for medium-scale infrastructure.
Others: Include helical and hybrid variations.
