Metallurgical Import& Export International Trading(Jingjiang) Co.,Ltd.

Product Description : Calorized refractory-coated lancing pipes are manufactured by rendering calorization finish to carbon steel in the thickness range of 230 – 400 microns on both the inner and outer surfaces. This is an aluminium diffusion treatment which promotes the fire-proof properties of steel pipes and High Quality Thermal Lance Pipe. This type of diffusion is an intermetallik bond, which does not get damaged either by mechanical working like bending or straightening or by temperatures. The calorisation treatment and the refractory coating give the MS pipes an extra ordinary higher life and resistance to corrosion at high temperature than that of ordinary ones and expensive stainless and alloy steel pipes normally used in oxygen lancing in electric arc furnaces and chemical factories and refineries. The average life of calorised and refractory coated pipes is 7 – 9 times more than that of ordinary pipes and stainless steel pipes. Colorized and refractory coated pipes are used in areas requiring high temperature and corrosive applications as follows: Heat exchangers, handling hot and corrosive gas. Finned Tubes. Gas ducts for SO2 & H2S gases. Reformer tubes. Regenerator tubes. Refinery flue gas tubes. Ethylene Pyrolysis furnace tubes. Oxygen lancing pipes in Alloy steel plants and copper smelters. The pipe is a low carbon special thin walled pipe, with high strength to weight ratio. The normal bore size and Wall thickness are as per standards. The calorising is upto a depth of 230 to 400 microns. Supply range: 1. Outer Diameter: From 21.4mm-60mm for your choice 2. Length: From 1 meters to 5.5 meters (customized) 3. Coating: 2mm-3mm (customized)
