High Density Polyethylene Pipe Services

HDPE Pipe is simply a pipe made of polyethylene; this material gives the pipes some special features which creates benefits and these advantages have led to the popularity of polyethylene pipes. The popularity of High-Density Polyethylene (HDPE) is primarily due to its low initial material cost and excellent chemical resistance. This allows thicker sections to be used compared to other geomembrane materials.

HDPE Pipes are flexible even at low temperature and have good adaptability to uneven underground. It is light in weight and its black color made it highly resistant to UV radiation. HDPE pipe is impact resistant and has more abrasion resistance than metal pipes. It is non-toxic and extremely resistant to chemicals, solvents, micro-organisms and radioactive waste water.HDPE pipes proved very successful in the main potable water supply, plumbing, drainage & sewerage, sprinkler & drip irrigation systems, firefighting networks, underwater piping system, laboratories, electrical conduits & fiber-optic ducts and gas distribution. It has a broad variety of industrial applications including the chemical industry, crude oil, mine slurry transportation and many other applications

HDPE liner with thick and durable property can be placed in exposed applications where the cost of other materials may be prohibitive. HDPE has excellent chemical resistance which is often the driving force behind the selection of HDPE. HDPE is a field assembled lining material that cannot be practically fabricated in the shop. All HDPE projects, regardless of size, must be installed by trained installers. HDPE is a versatile material which is used widely across all applications. One of the main uses of HDPE is for landfill base liners where its chemical resistance is used to good effect. HDPE can also be used in a multitude of secondary containments, pond linings, and water containment projects. HDPE is best used as an exposed lining material, and has the UV resistance required for many years of outstanding service.

HDPE Welding and Jointing Services

Bisco has Expertise in all HPDE-related maintenance, Welding and Jointing works. Several types of joining methods are available for HDPE pipes and it depend on the size and type of application. The first common type of Joining HDPE pipe is Mechanical Joining which compose of Compression type and Flange type, and the other is the Permanent Joining which compose of Butt Fusion Welding and Electrofusion Welding

Butt Fusion Welding (HDPE Pipes)

Butt welding or Butt Fusion is a simplest and space-saving jointing method to connect the pipe and fittings of PE. The process starts by cutting the pipe ends straight and square to the axis and cleaned carefully by and electric planer. The pipes and fittings are held tight and pressed against a coated heating plate. As soon as the heating time and the required bead are reached, the heating plate is quickly withdrawn from the weld faces and the connection are pressed together to form a permanent joint.

Electrofusion Welding(HDPE Pipes)

This is an easy system for jointing pipes and fittings of HDPE. A pre-installed resistance wires are embedded in the inside surface of the electrofusion coupling. When the pipes or fittings are inserted in the coupling and the wires are connected to the welding unit, the contact surfaces become warm and consequently melt into each other until it forms a rigid and durable joint. A welding unit is available for this procedure which operates the timing automatically. This makes the whole operation very easy and practical especially in narrow and tight installations.

Extrusion Welding(HDPE Liners)

Extrusion welding is a finishing technique where a bead of molten plastic is used to weld thermoplastic geomembrane materials. The quality of an extrusion weld is dependent on the skills of the welder operator. Extrusion welding machines use a heated barrel with a plasticizing screw to deliver molten plastic to a specially shaped shoe. The shoe is shaped to make a bead of plastic suitable for the material type and thickness being welded. A hot air blower is attached to the extrusion welder to preheat the weld area. The welder uses its own weight to create the pressure required for welding and the operator steers the welder manually

Wedge Welding(HDPE Liners)

Wedge welding machines use a heated element to fuse thermoplastic sheet materials. Wedge welders are automatic machines that run between two overlapped sheets of material. The welder heats the interface between the materials and then presses the materials together to form a lap weld. The thermoplastic materials are fused at the molecular level without the addition of any glues or solvents.
