At Haplast you will find smooth extruded PE pressure pipes in optional SDR classes with diameters from 32mm to 1000mm. We manufacture according to customer requirements and for the vast majority of applications within water and sewage.
Haplast covers your pipe needs
Haplast can supply pressure pipes in SDR class according to your needs - also SDR11 with blue stripe. We produce standard lengths of 6 and 12 meters, coils and tows. With immediate proximity to the Lyngenfjord, we can offer tow lengths up to 250 meters. Other lengths are available on request, see our dimension table for an overview of available products.

Flexible solutions
PE is increasingly being chosen as a material for water supply in Europe. PE is a strong and flexible material that is suitable for most applications. PE-pipe is used as water pipes for drinking water, sea pipes, transmission lines and pump pipes, or for pumping sewers and discharge pipes in the wastewater sector.

Long service life
PE is a thermoplastic that does not emit odor or taste, has a long service life and is a good electrical insulator. The material is flexible and does not react chemically with water. PE does not corrode and has a long service life (100+ years). The pipes can be joined with screw couplings and flange connections, but for a 100% tight result, we recommend welded connections with mirror welding or electrofusion welding.
Durable solutions
Does not corrode
PE does not corrode, does not react chemically with water and is resistant to most acids, alkalis, solvents and oils.
Flexible
PE-pipe can normally withstand freezing when filled with water. This is because the material is thermoplastic and expands 10% when the water freezes. If the pipe is thawed within a reasonable time, the pipe will return to its original shape. The service life will be reduced if pipes are frozen for months on end. PE pipe is impact resistant and flexible even in extreme cold. However, the material's E-modulus increases rapidly with decreasing temperature and the material's ability to absorb rapid impacts is reduced. The material appears stiffer and is harder to bend in extreme cold.
Heat leading ability
PE is a poor conductor of heat. This means that it takes a long time for a pipe to freeze. In special cases, the laying depth can be reduced.
Low weight
PE pipes are lightweight. This allows for easy transportation and handling.
Friction
PE pipe is smooth and is considered virtually smooth. This provides little friction and reduces the risk of deposits and algae growth inside the pipe.
Impact-resistant material
The pipes are designed with a very high level of safety. As a general rule, pressure surges are permitted as long as the average pressure is below the specified PN.
Long service life
Today's materials are expected to last >200 years at +20 degrees and full static pressure. Chemical service life is stated to be >500 years. Low temperatures and salt water increase the lifespan considerably.
Tensile joints
The end user gets a leak-free network when water and sewage systems are laid with fully welded PE pipe. pipe is supplied in long lengths, with few tensile joints and with joints that do not corrode.
