These HDPE pipes and fittings have a high degree of corrosion resistance, are light in weight. Yet tough and durable, have excellent, hydraulic properties, excellent thermal properties, weather ability. High density polyethylene (HDPE) is being used as drainage pipe material because it is lightweight, corrosion resistant, easy to install, and has a low maintenance cost. The design of HDPE corrugated drainage pipe is based on the assumption that the pipe will deform and thus relieve stress.
HDPE pipe has been used for decades in non-potable water applications. In particular, HDPE pipes are often preferred for their welded joints. While special equipment is required to form the weld, welding eliminates the need for separate fittings, a common source of leaks and contaminant infiltration.
HDPE can be used for hot water as a liner in multilayer pipe, where the strength is provided by another pipe layer, such as aluminium, but multilayer pipes don’t offer all of the performance advantages of plastic alone.
Polymers are classified into thermoplastics and thermosetting. The industry has expanded along with expansion of diverse applications areas such as packaging, extrusions, blow mouldings and industrial mouldings for automobiles, telecommunications and white goods. User segments include electrical appliances, domesticware, leatherite, decorative laminates, fittings and fixtures, construction industry (extrusions), automobile components, machinery and equipment, water tanks, pipes and fittings, drink bottles, medical appliances, weather protection. The Indian industry has created enough capacity to export polymers in substantial quantities. In 2006-07, India exported close to 17% of its polymer production. However, import of polymers continues unabated at a growth of 11% (2001-02 to 2006-07) per annum, and makes up for nearly 14% of the domestic consumption. Despite the slowdown, the plastic industry has seen a fairly high growth in 2008-09. As a whole any entrepreneur can venture in this project without risk and earn profit.
