As a pipe jacking trenchless underground pipeline construction method, without land, without affecting the pavement structure, and it is also convenient to cross roads, railways, buildings, rivers and so on laying underground pipelines. It has little influence on the traffic and environment, the excavation is less, and the mechanization degree can be adapted to the special conditions. It is considered as a kind of modern underground pipe laying method.

We can provide all kinds of pipes including: FRP pipes Oilfield: sewage delivery pipeline, crude oil delivery pipeline, etc. Chemistry: anti-corrosion pipe in chemical plant, pipeline of power plant.
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 diameter Nominal size of pipe and fitting is based on internal diameter. The range of available sizes is 25 to 3000 mm. Nominal pressure classes: Pipes and fittings 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 conditions Nominal lengths Pipes have a length of six meters up to nd150 and 12 meters for bigger diameters. Fittings A wide range of fittings as elbows, reducers, tees, caps, flanges etc. Is available. Fittings are manufactured by the hand lay-up, contact molding and spray-up process. In hand lay-up and contact molding processes veil and alternate layers of mat and woven roving saturated with resin are applied on the mold. In spray-up process continuous strand roving is fed through a chopper gun, combined with catalyzed resin, and sprayed onto the mould surface Prefabrication spools Prefabricated spools save installation time as well as costs, freeing the designer from being limited to standard fittings and allowing junction sizes shapes to be specified and manufactured as a better alternative to a complex series of joints.
FRP Pipe.
Product Name: SBB FRP pipe Product Introduce: FRP cable protection pipe, glass fiber as reinforcing material, and unsaturated resin bond forming.

Specification size: Nominal diameter: 50-200mm. Wall thickness: 3.0-5.0mm, 5.0-10mm.
Coupling 45 elbow 90 elbow Tee Reducing tee Flange Field thread Nipple Reducer .
FRP Filament Winding Pipe is formed by using high strength alkali-free fiberglass roving andunsaturated polyester resin after curing by winding process. The workingtemperature is general -40 C-80 C. The special ratio of the pipeline makes itable to withstand the high temperature of 110C. It will not crack in thefreezing environment, without maintenance. Products arewidely used in city power grid construction and renovation project,reconstruction project, industrial zone, residential project construction,traffic road, bridge construction, etc. FRP/GRP Mortar Pipe As the RPM pipe is accompanied with sand in its structure,compared withthe pure FRM pipe,it not only-has property of lightweight and high strength,butalso possess high stiffness as the buried pipe and low cost.So it is welcomedfrom its presence.The usage in conveying water or other fluid is more and more. Excellent foodgrade performance Good cold andheat resistance Excellent wearresistance Good insulationperformance Non-toxic, nosecondary pollution Small specificgravity and light weight Few interfaces,high installation efficiency Good mechanicalproperties, excellent insulation properties Excellent hydraulicperformance, saving energy Connection accessories: Socket type, Butt type, Flange type, O-ring type elbow, T-tube, reducer, Flat welding flange, etc.
High strength, the inner surface is smooth (friction coefficient is small, the cable is light and smooth, no damage to the cable) , light weight (weight only 1/4 of steel pipe, concrete pipe 1/10 or so, transport is convenient, installation is simple) , not deformation. No galvanic corrosion, non magnetic, suitable for single core cable laying, will not produce eddy current. Good corrosion resistance, high water or seawater erosion performance. Heat resistant, can be used in 120. Insulation, corrosion resistance, no rust, the service life of 50 years or more do not have to maintain, a benefit for life. D=100~200mm Nude packing
