hdpe pressure pipeHDPE Pressure Pipe

Oxford Plastics manufactures hdpe pressure pipe for a broad and diverse assortment of applications. Hdpe pressure pipe is made from high density polyethylene which is a crystalline resin or polymer known for its flexibility, toughness and chemical resistance. These features make hdpe pressure pipe well suited for those applications or industries requiring a pipe that is strong, durable, corrosion resistant and yet flexible enough to be assembled and installed in the most inaccessible and harsh environments. It is the preferred pipe of choice for most trenchless technologies like pipe bursting and horizontal direction drilling. If you have a project requiring a piping solution that can handle extreme loads of pressure under harsh conditions, hdpe pressure pipe is definitely worth considering.

Construction and Features of HDPE Pressure Pipe
Our HDPE PE 3408 pipe is manufactured in accordance with AWWA, ASTM, FM, CSA, BNQ, and NSF Standards. Made from a high density polyethylene polymer, hdpe pipe has certain physical characteristics that make it an attractive pressure piping solution. Because of its molecular structure (much longer chains with fewer side branching) polyethylene pipe has greater density and a crystallinity level in the range of 85%. As a rule, when the density increases, the stiffness, harness, strength, heat distortion point, and ability to transmit gasses increases. When density decreases, impact strength and stress crack resistance increases. (Stress cracking is a surface change that polyethylene will undergo when exposed to oils, gasoline and other hydrocarbons). Rated at a density range of 0.941 to 0.965 gr/cc, hdpe pressure pipe is superior in stiffness, hardness and strength making it ideal for pressure applications.

The molecular structure of hdpe pipe gives it certain advantages over other plastic pipe. Most importantly, it can handle greater pressures under extremely corrosive conditions. For instance, it can be buried to great depths and can tolerate severe soil strain and soil movements (rise or settlement). It is even earthquake tolerant…being seismically qualified in the lab and field proven. When buried at these great depths, it also helps when a piping system is capable of handling the transfer of extremely corrosive materials, i.e., industrial wastes and chemical acids.

Applications of HDPE Pressure Pipe
Our hdpe pressure pipe was manufactured for a wide range of industrial, commercial and residential applications. Our broad experience with industries from construction and waste to agriculture and mining, has helped us to develop pressure pipe and piping systems that can operate under great pressure and in very corrosive environments. This makes our pipe well suited for use as watermain, landfill collection pipe, drainage pipe in highway construction, agriculture, mining, and irrigation industries, and as industrial transfer pipe for abrasive materials. The physical toughness of this pipe, when combined with its light weight and flexibility, makes it perfect for those situations where trenchless technologies are required.

Advantages of HDPE Pressure Pipe
HDPE pressure pipe is probably your best choice as a pressure piping solution for two important reasons. Since hdpe pressure pipe is fusion welded together and the weld is as strong as the original pipe, it is a monolithic or one piece pressure piping solution. This makes it ideal for pressure applications compared to other piping materials such as PVC or ductile iron pipe, and others, which have a bell and spigot, or possibly a flange joint every few meters making them susceptible to possible leaks or pipe/pressure failure. Secondly, when any pipe or piping system is under extremely high pressure, the joints must be restrained to keep from bursting apart. In most cases, joints, bends, tees, caps, etc., are anchored with mechanical restraints or blocks of concrete, so that the joint doesn't pull apart. A concrete block at a restrained joint is called a thrust block. Hdpe pipe, on the other hand, is one continuous piece making it self-restrained, i.e., requiring no mechanical restraint.
