Steel Pipe

HDPE pipe reinforced by steel frameThe pipes is very advanced & modern ones, so that the pipes represents the development trend of pipelines in the world and enjoys a reputation of (Green pipelines of the 21st century) . Excellent corrosion resistance, pressure bearing capability, heat preservation & wearing resistance, steel mesh can expand orContract along with plastic pipe according to the change of temperature, etc.The pipe has being widly taken to instead of steel & stainless steel tube, iron casting tube, and other plastic pipes.

Burst testC. 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 impactResistance, rigidity / dimension stability & proper flexibility, good pressureBearing 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, finishidPetroleum conveyance, transportation of polymer solution to wells stc. It is especiallySuitable 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, petrochemicalIndustry, chemical fertilizer production, pesticide production & pharmacy, etc forProcess tubing & drainage pipelines to convey corrosive mediums. 4. Ship building: used for living pipeline system, structural & waste woter pipeline5. Coal mines: used for transportation of coal-water slurries, coal bed gas & ash, etc.6. we mines, metallurgical industry, electricity generating & food industry, etc.
