Welded Pipe

 

The pipe mill at Hazira is one of India's finest, with a capacity of 0.6 MTPA and the only one in the country with an integrated raw material source. The API-certified pipes find wide acceptance and approval from international oil and gas majors.

The pipe coating unit has an annual external coating capacity of 2 million square meters and an annual internal coating capacity of 1 million square meters. It deploys external coatings such as fusion bonded epoxy (FBE), dual layer FBE, 3 LPE, 3 LPP and polyurethane to prevent corrosion, as well as liquid epoxy solvent base and solvent-free internal coating to improve product flow.

Quality enhancing features include

• Produces high strength line pipe grades, up to X80 .

• H-SAW and L-SAW manufacturing

• Inside and outside welding by automatic SAW.

• Continuous tack welding

• A well-equipped testing laboratory helping ensure compliance with international standards: ultrasonic testing, real-time radiography (fluoroscopy), hydro-tester and final ultrasonic testing (automatic weld cut).

• External and internal coating facilities.

• Shot blasted and painted pipes.

• A fully automatic expander with a CNC machine that minimizes residual stresses and improves mechanical properties, ensuring tight and uniform control on dimensions.

• End bevelling
