Steel pipe for hydro power
Penstock water is an important part of building hydropower stations, it is exposed to the reservoir under pressure forebay or surge chamber water pressure conditions, the water into the volute, turbine rotates promote or introduce water into the other equipment to meet supply requirements. Arrangement of the penstock is based on topography, geological conditions and retaining, different forms of hydropower diversion structure to determine the location. Common form of penstock layout: Ming pipe, underground pipe, backfill pipe, penstock, dam pipe and so on. Force pipeline from the reservoir, pressure forebay or surge chamber to the turbine pipes conveying water, typically pressurized state. Its characteristics are concentrated most or all of the head hydropower, another steep slope, the water pressure, but also to withstand the impact of hydrodynamic pressure (water hammer pressure), and close to the plant, once the damage would be a serious threat to the safety of the plant. So pressure pipe has a special importance, its materials, design methods and processing techniques have special requirements. Penstock pipe is generally graded by imports, the flat tube, the elbow, oblique tube (or shaft steel), the next bend, the next flat tube, fork, branch pipe. The main components include penstock pipe, elbow, taper pipe, gradient tubes, fork tubes, expansion joints and pipe accessories on (such as support ring, stiffener ring, sealing ring, anchor tendons, into the hole, filling holes, etc. ), as well as bearings and other parts out tube.
