Hoop rigidity 6. mannesmannrohren service gmbh, germany. Burst test C. Advantage compare with 1) metallic pipes,2) pure plastic pipes: 1. excellent corrosion rssistance on both internal&external sides, light weight, good temperature resistance, ultrasmooth inner surface, hence very low friction loss, good wearing resistance, non-toxicity&inert to decompose, long service life expectancy over 50 years. Above are compare with metallic pipes. 2. good creep resistance&high long-term mechanical strength, excellent impact resistance, rigidity/dimension stability&proper flexibility, good pressure bearing ability&crack will not occur to it, low thermal coefficient, easy to be located&traced, above are compared with pure plastic pipes. D. The application of the pipes are as follows: 1. Oil field: Used for crude collecting, sewage disposal, crude transpotation, finishid petroleum conveyance, transportation of polymer solution to wells stc. It is especially suitable for transportation of mediums of oil, gas, and woter with high sulfur content. 2. Civil engineering: Used for water supply&drainage piperline, natural gas. 3. Chemical industry: Applicable to acid, alkali&salt manufacture, petrochemical industry, chemical fertilizer production, pesticide production&pharmacy, etc for process tubing&drainage pipelines to convey corrosive mediums. 4. Ship building: Used for living pipeline system, structural&waste woter pipeline 5. Coal mines: Used for transportation of coal-water slurries, coal bed gas&ash, etc. 6. We mines, metallurgical industry, electricity generating&food industry, etc. Wellcome clients oversea to cooperate&trade with us.
