To realize a polyethylene pipe with high strength and a high modulus of elasticity, a polyethylene based composite pipe was tentatively fabricated. To retain the plasticity of the composite pipe, polyethylene yarns were used as reinforcement. It was an interface-less composite because the reinforcement and the pipe base were of the same material. A micro-braiding technique was introduced to fabricate the polyethylene yarns. This pipe showed an excellent long-term creep strength compared with polyethylene-based composite pipes reinforced with other kinds of resin.

Osaka Gas has carried out the production, supply, and sale of gas since 1905 and has distributed gas to 7,200,000 customers. The piping used for distribution was originally steel and cast iron pipes, but we have been adopting the use of polyethylene piping for low pressure distribution since 1980, and have to date...

This study explores the Japanese market for polyamide 12 (PA12) pipes in terms of new product market success. To gain the market penetration, there are various entry barriers for the new product in the new market field which has big distance between current marketing areas and target country. In spite of becoming...

Pipe materials that are resistant to damage by thirty-party works were investigated with attention to materials already used for other purposes. Pipes for underwater cables, water service and agricultural use, both multiple-layer and single-layer types, were selected for the test. Protective materials were also...

Pultrusion process is one of the composite production methods that have been used for mass production of uniform profiles. However, there are two problems that are commonly found in pultrusion products; one of which is its anisotropic mechanical properties. This anisotropicity stems from the alignment...

Electrofusion (EF) joints have been widely used as easy-to-fuse and high-quality joints for joining polyethylene (PE) pipes. When we introduced EF joints 150 mm or more in diameter, an electrofusion simulation program was concurrently developed to reduce time for design and experimental works. It was verified that the...

To estimate the long-term performance of polyethylene pipe, molecular structure of polyethylene resin were analyzed and the long-term performance test were done. By linking the molecular structure of the resin to the results of long-term performance tests such as tensile creep tests and tensile fatigue tests, it...
