The first PE pipe material used in engineering appliions was Type 50 High Density PE HDPE with a long term stress of 50MPa. Subsequently, Medium Density MDPE materials, with improved pipe properties when compared to the earlier high density materials, were used in pipes due to their improved flexibility, ductility, slow crack growth resistance and crack propagation resistance.
Introduction. Both corrugated high density polyethylene HDPE and Polyethylene PP pipes are available for a variety of appliions. These appliions include gravity flow storm and sanitary sewer, low head pressure appliions as well as many others as deemed appropriate by the design engineer.

6 Pipe bursting project saves time and money As part of its sewer rehab project, the city of Baytown, Texas, elected to use 36-inch HDPE pipe to replace 36-inch Reinforced Concrete Pipe RCP sewer lines. To burst more than 3700 feet of pipe in residential areas
Due to its good chemical resistance, large-bore HDPE pipes are ideally suited for trade wastes and is being used to an increasing extent as an underground sewer pipe. In submarine lines, pipe flexibility is utilized to accommodate the pipe to the profile of the waterway bed without the use of separate fittings.

4 PE PIPE—DESIGN AND INSTALLATION Creep is not an engineering concern as it relates to PE piping materials. Creep refers to the response of PE, over time, to a constant static load. When HDPE is sub-jected to a constant static load, it deforms immediately
PE & HDPE Pipe PE100 is the third generation of pipe grade PE. It has an optimum balance of three key properties: Minimum Required Strength MRS – this provides long-term strength and creep resistance. Stress crack resistance sometimes referred to as slow crack growth resistance. Puhui Pipe manufacturer in China
Features of HDPE pipes and fittings: Green environmental protection: HDPE pipe non-toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality. Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.

Smooth HDPE is easily fabried and features good chemical resistance, tensile strength, and is moisture and impact resistant. One of the most common appliions of HDPE smooth sheeting is pipes lining. HDPE Pipe Grade Pipe grade HDPE plastic features
Its electrical properties, particularly at high frequencies, are very good but LDPE''s are even better. Its barrier properties, though indifferent, are better than those of LDPE. liions include a wide range of containers, blown bottles for food, pipe and pipe fittings and packaging films.
