Experiences in the Implementation of PAS 1075
The development of PE 100 materials has resulted in PE 100-RC, which is resistant to slow crack growth in accordance with PAS 1075. This specification details the dimensions, requirements, and testing protocols for PE 100-RC pipes used in alternative installation techniques. Experiences gained from implementing PAS 1075 address various questions related to these techniques.
14th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days)
At the 14th Wiesbadener Kunststoffrohrtage (Wiesbaden Plastic Pipe Days), Dr. J. Hessel presented on the mechanical and thermal limits of PE 100-RC, introducing new creep rupture curves and discussing enhancements in thermal aging for improved temperature resistance.
2nd Internationale Fachtagung - Kunststoffe im Anlagenbau
At the 2nd Internationalen Fachtagung "Kunststoffe im Anlagenbau" (International Conference "Plastics in Plant Engineering") in Munich, Dr. J. Hessel presented on the calculation of the remaining service life of polyethylene pipes after long-term use.
Cost- and time-saving method for generating creep curves for plastic pipes.
The strength-related design of plastic structures is typically conducted using creep rupture curves. This article describes a testing method for generating reliable creep curves for thermoplastic pipes, aimed at reducing uncertainties in calculating the minimum stress over a 50-year lifespan.
Sewerage And Drainage Pipe 2009, Köln, Deutschland
The conference covered key topics related to plastic pipe connections, including a presentation on the material requirements for PE pipes used in the relining of sewer pipes. J. Grieser’s talk focused on the challenges associated with stress-cracking substances.
