Penstocks Pipe

PENSTOCKS PIPE: The factory is equipped with sophisticated machinery and equipment required for the fabrication and erection of penstocks and penstock specials like expansion joints, Wye pieces, bulk heads and other products like LPG Storage Tank, Boiler Shells, Cement Kilns etc.

PROGRESS: A Penstock is a high pressure steel pipeline that carries water from the storage reservoir to the turbines and is a vital element of hydro-electric projects. The design, fabrication and erection demand a high degree of skill. Until the late thirties, penstock and even technicians had to be brought from abroad.

QUALITY CONTROL: Quality control is an essential part of fabrication and erection of penstocks. Depending upon the basic steel material used for penstocks, the matching welding consumables are selected. Particularly, while using 'quenched' and 'tempered' steel, electrodes with low hydrogen content are to be baked and kept dry before use and while welding this steel, it is very essential to strictly control the pre-heat temperatures, inter-pass and post-heat temperatures. The company has wide experience in the welding of special steels requiring rigorous quality control procedures and our technicians have mastered these techniques.

SPECIALS: The design, fabrication & erection of extra high tensile steel Penstock Specials, capable of withstanding very high pressures is a challenging job. IHP technicians have, during the past several years successfully designed, fabricated and erected various types of specials like ring girders, rockers, transitions, bell mouths, expansion joints, flexible couplings, wyes (bifurcation and trifurcation pieces), surge liners for surge tanks, bulkheads etc.
