High Frequency Induction Welded (HFIW) Oxygen Lancing Pipes. Oxygen lancing Pipes are Manufactured from hot rolled Carbon Steel.

END USES

These pipes are used for blowing oxygen in electric arc furnace.

SIZES

6 mm NB to 40 mm NB Outside diameter: From 9.5 mm to 48.3 mm , Wall thickness: From 1.80 mm to 3.20 mm Length: up to 7.00 mtrs.

PIPE ENDS

Plain, Threaded or Non Threaded with crimping coupling.

SURFACE FINISH

1) Black (self-colored)
2) Ceramic coated (inside as well as outside) Ceramic coated lancing Pipes have number of additional characteristics.Increased resistance against heat & erosion. Longer life resulting in speedy de-carborization & better metal oxygen interaction. Cost effectiveness: The above factors result in power saving, lower consumtion of electrodes, and lower melting time

PRODUCTION STANDARDS

Confirming to IS -10577.

PACKING

Black lancing Pipes in Bare bundles. Ceramic Coated Pipes in special hessian cloth.

INSPECTION

Mill's certificate or inspection by an independent agency.

TESTS PERFORMED

Dimensional Checking, Hydro Testing (Pressure Test), Flattening Test, Drift test.
