We can design the new pipe profile according to the new material, customer’s site situation and requirement.

We can make static calculation of HDPE spiral pipes to guarantee the safety and life time. An SN class 2,4,8 or higher classification according to ISO9969/ASTM F894/DIN16961 will not give an indication, if the product has the necessary safety reserves under a short term or long-term proof. The calculation standard is ATV A127 and M55. The engineer can calculate the profile design for most embedding condition and ensure the spiral HDPE pipe can work for 50 years with long term proof.

It is very important to make the static calculation for new profiles design to get the best design with good ring stiffness and lower weight. It is can save money and reduce the cost. The most advantages of PP and PE is the flexibility, leading to a small and controlled deformation under load, even under overload just the deformation will increase, however there will be not break and no leakage. Spiral profile pipes which are far too stiff will react more than a rigid pipe than a flexible one. This will lead to less deformation, but at the same time the risk of breaks and leakages is a major problem.

Both, the saving of natural resources and the engineered design, are necessary to guarantee the quality of the product now and in 50 years.

We supply the design and fabrication equipment for spiral tank and manhole.
