          FRP Pipes and Fittings Filament winding FRP pipe with sand filler / FRP Mortar Pipe

          JIANDE QIANXI CHEMICAL EQUIPMENT CO., LTD manufactures filament wound pipes & ducts of different diameter in accordance with standards published by ASTM, ANSI, AWWA, ASME . Pipes & ducts are manufactured from corrosion resistant epoxy vinyl ester, polyester, isophthalic resins.

          Executive Standard: Fiberglass enwinding enhanced thermosetting resin pipe.

          FRP Mortar Pipes: ISO9001

          1) FRP pipes with excellent mechanical physical properties. Light weight, high strength, Specific gravity of mortar pipe is 1.65-2.0, is only 1/4 of steel’s, hoop tensile strength is 180-300MPa, axial tensile strength is 60-150MPa, using socket connection, easy transportation and installation;

          2) High and Perfect corrosion resistance, no effect on water quality:

          FRP pipes can be resistant to acid, alkali, salt, sea water, sewage without treatment, corrosive soil or groundwater, and erosion from various chemical fluids.

          3) Excellent hydraulic characteristic, which is one of the most important features to FRP pipes, it means FRP pipes can significantly reduce the fluid pressure loss along the way and increase transmission capacity and then can choose smaller pipe dia. size or smaller power delivery/transfer pump so as to save the cost invest for the pipeline engineering at the initial stage, also save electric energy and lower operating cost.

          The Inner wall of FRP pipe is very smooth. Roughness coefficient is 0.0084, but concrete pipe is 0.014 and cast iron pipe is 0.013. The Small frictional resistance, high transmission capacity is fantastic, almost regards as “the best smooth pipes for engineering hydraulics and also in service, the surface of any steel pipes, cast iron pipes and cement pipes etc are always happening with localized corrosion and then becoming worse and worse rough and rusty, and the FRP pipes always keep the perfect smooth surface as new ones, it is so important to water quality then.

          4)Anti-fouling and anti-moth

          The surface of unsaturated polyester resin is clean and smooth; it will not be defiled or attached by microorganism such as armour shellfish and fungus in the ocean sewage.

          5)Good heat resistance and frost resistance:

          In -30℃ condition, mortar pipe still has good toughness and high strength; it can be use in the range of minus 50℃ to 80℃ for a long term, it can also used in temperature above 110℃ condition with a specially formulated resin.

          6)Good electrical and thermal insulation:

          Insulation resistance is in the range from 1012 to 1015Ω.cm, heat transfer coefficient of FRP material is very small, only 0.23.

          7)Good wear resistance and Low maintenance costs:

          Normally, the FRP pines don't need special antiseptic treatment, insulating layer can be thinner and even don’t need to do with extra insulation treatment; as pipes is light and so can require some small tonnage of hoisting equipments and so less power consumption.

          And FRP pipes is longer than iron cast or cement pipes, so less joints too,

          As No need precaution and maintenance for rust-proof stain resistant, insulation and thermal insulation. No need cathodic protection for underground pipe, all these will help to save more than 70-80% of the engineering installation and maintenance cost, it has been approved and certificated by many engineering practice aboard.

          8)Good adaptability, Flexible design and shorter reform term

          Pipes & ducts are manufactured using the "Dual helix" filament winding process on computer controlled machines. By adjusting the relative speed of mandrel rotation and glass distribution head movement, helical reinforced layers with different angles can be wound. In order to increase the pipe stiffness, especially on large diameter pipes, silica sand can be added to parallel layers of wall.

          Nominal size of pipe and fitting is based on internal diameter. The range of available sizes is 25 to 3000 mm. Pipes and ducts are classified according to nominal pressure. Standard pressure classes are 4, 6, 10, 16, 20 and 25 bars. Intermediate or higher-pressure classes are considered on request or depending on the design parameters and condition.

          Design pipe with different pressure class and stiffness based on client’s specific requirements.

          9) Long service life, safe and reliable. Lasting Performance Environmental Protection

          Laboratory simulation experiments show that: Service life of FRP pipe can reach more than 50 years.

          10) Good comprehensive benefits:

          The comprehensive benefits of FRP pipe is desirable, especially the larger diameter, the lower its cost. Underground pipes can use for a long time without maintenance every year, thus it can obtain a excellent comprehensive benefits.

          FRP Mortar Pipe

          FRP pipe is consisting of resin (select food grade resin for transmitting drinking water), glass fiber and quartz sand, manufacture uses a special process.Its operating temperature is below 80 ℃, suitable for various soil.
