Pipa Baja SSAW
Pipa baja SSAW uga dikenal minangka Spiral Submerged- Arc Welded Steel Pipe sing kalebu jinis pipa baja gandheng spiral sing diproduksi kanthi nggunakake metode las busur kaping pindho. Pipa gandheng spiral dibentuk nggunakake piring sing luwih sempit utawa koil sing digulung panas, sing nyuda biaya produksi kanthi signifikan. Proses las spiral ngidini produksi pipa diameter gedhe sing cocog kanggo ngeterake minyak lan gas kanthi volume akeh.
