HOBAS pipe diameter of 100 price quotations manufacturer

Hebei Dongsheng GRP Ltd.: HOBAS pipe Process Description: 1, the implementation of standards: production, inspection and acceptance of Fiberglass Reinforced Plastic according to JC / T838-1998 "winding glass fiber reinforced thermosetting resin sand pressure pipe" or CJ / 3079-1998 "glass fiber reinforced plastic sand pipe" standards. 2. Prepare materials: an examination under working conditions determine the specifications of raw materials, models, after the raw materials into the plant, and the inspection report. 3. Process: system liner - wound - dressing - Stripping - test - lined storage 4. Production: The mold is placed in the pipe system liner station, wrapped around a layer of polyester film on the tube mold and then coated with a layer of gel coat, until the gel layer, and then wrapped around the glass surface mat and glass fiber chopped strand mat, and then wrapped around a layer of mesh fabric, lining and then winched to mold curing station innerliner curing process. 5. The structure layer wound: After curing liner, and then place the pipe mold winding station, the E-wound yarn impregnated resin according to design procedures and processes ply wound onto the inner liner, then add the amount of sand design The size of the quartz sand layer by layer is applied to the mold, followed by extrusion lamination apparatus dense sand compaction, according to the production process after adding sand, conduct fiber cross-winding and winding hoop. Thus, the great strength of the fiber-wound layer by bending stress distribution in the largest inner and outer layers, and strength than the bottom layer of quartz mortar distribution role. Then hanging pipes and mold to the curing station for curing processing structure layer. 6. trim, stripping: pipeline to be fully cured after winding, the place to repair station on both ends of the pipe socket slotting grinding, then meet the requirements, then the tube is placed on the stripping machine, the pipeline Unplug the finished mold from the pipe, glass pipe the entire production process is completed, and submitted to the inspection process. 7. testing, storage Fiberglass Reinforced Plastic Features 1. corrosion: RPM pipe resistant to acid, alkali, salt, water, untreated sewage, corrosive soil or ground water and many other chemical fluid corrosion. Generally steel useful life of 15 years, cast iron pipe was 5--10 years, while the life of RPM pipe can reach 50 years or more. 2. Antifouling anti-algae: Because of its smooth inner surface, while maintaining long-term change. Therefore, it will not be the medium of various microorganisms to produce algae Jifu. The metal or cement pipes with the passage of time and produce more algae. 3. Heat frost resistance: Temperature Range RPM pipe is generally between -40 ℃ ━80 ℃, if the first with a special resin which can reach a higher temperature. 4. Long life of the project, the design is safe and reliable: Under normal circumstances, the design safety factor of 4 or more in the pipeline, it will ensure the durability of the product in use. According to the results of laboratory simulation of their life up to 50 - 100 years.
