Ni-Hard Pipe
Ni-Hard pipeis used for abrasion resistant applications where there is extreme temperature. It is used for handling coal fly ash in thermal power plant. Our Ni-hard pipe offers excellent abrasion resistant propertiesin extreme high temperature environment.High content of nickel in our Ni-hard pipe promotes austenite grain formation which causes these pipes to become abrasion and heat resistant.
We manufacture Ni-hard pipein various size and dimension. Weight of each Ni-hard pipe manufactured by us can range from25 kgs. to upto 500 kgs. single piece. We accept large quantity order for Ni-hardpipes. Ni-hard pipe is manufactured as per IS : 4771 – 1985 type 1A to upto type 3
All the Ni-hard pipeis properly and strictly checked for its chemical properties on 37 channel analysis Spectro Inc. Germany make spectrometer by tapping liquid metal directly from the induction furnace. Ni-hard pipeis generally used in the as cast condition. But for heavier section thickness pipe it is perfectly annealed in a state of the art electric hearth heat treatment furnace having programmable PLC based temperature controller and chartless recorder.
After the annealing heat treatment process is complete metallography test of samples is done on a 1000x magnification metallurgical microscopealong-with support of image analysis software both imported from Italy to determine the grain structure and matrix formation which in-turn helps to know thesoundness of the Ni-hard pipe. Hardness is than measured directly on the pipe using digital hardness tester imported from Proceq Switzerland.
We are supplying Ni-hard impeller tothermal power plants located in Jharkhand, West Bengal, Chhattisgarh and Uttar Pradesh.
