Follow these general steps when performing socket fusion: 1.Select the equipment 2.Square and prepare the pipe ends 3.Heat the parts 4.Join the parts 5.Allow to cool Butt Fusion Joint The most widely used method for joining individual lengths of large diameter polyethylene pipe is by heat fusion of the pipe butt ends.This technique, which precludes the need for specially modified pipe ends or couplings, produces a permanent, economical and flow-efficient connection. Field-site butt fusions may be made readily by trained operators using specially developed butt fusion machines that secure and precisely align the pipe ends for the fusion process. The six steps involved in making a butt fusion joint are:
  7. 7. 5 1.Securely fasten the components to be joined 2.Face the pipe ends 3.Align the pipe profile 4.Melt the pipe interfaces 5.Join the two profiles together 6.Hold under pressure Electro Fusion Joint This technique of heat fusion joining is somewhat different from the conventional fusion joining.The main difference between conventional heat fusion and electro fusion is the method by which the heat is applied. In conventional heat fusion joining, a heating tool is used to heat the pipe and fitting surfaces.The electro fusion joint is heated internally,either by a wire coil at the interface of the joint or, as in one design, by a conductive polymer.Heat is created as an electric current is applied to the conductive material in the fitting. General steps to be followed when performing electro fusion joining are: 1.Prepare the pipes 2.Clamp the fittings and pipe(s) 3.Apply the electric current 4.Cold and remove the clamps HDPE pipe for dredging DN/OD: 75mm - 900mm Materials: PE100 Brand OEM: YES Fittings offered: HDPE flanged adaptor,bolts&nuts, Rubber blanket, PE floater, Rubber hose.

Steel mesh reinforced HDPE pipes (SRTP pipes)&fittings for water supply DN/OD: 50mm – 630mm Materials: PE100, Steel wire Color: Black with blue line, Black or as client’s requirement. Fittings offered: Electro fusion fittings 1.Product structure This series of products are new-type medium, high or low-pressure composite pipes reinforced by high-strength plastic-covered steel wire and covered with composite thermal plastic at internal and external surface. Owning to the reinforcement is covered in continuous thermal plastic, this kind of composite pipe not only overcomes shortcomings of steel pipes and plastic pipes, but also has common advantages of steel pipes and plastic steels. After the galvanized pipe is prohibited, it is a revolutionary technological achievement for architectural and municipal water supply pipe and also solves the urgent needs for large-diameter rigid pipes in petroleum, chemical engineering, pharmacy, food, mine and gas field, etc. The piping system of steel wire mesh plastic reinforced composite pipe is equipped with electric melting pipe fittings. During connection, the heating elements in fittings will melt outer plastic on pipe and inner plastic on fittings and then connect them together reliably.
  13. 13. 11 2.Product characteristics ● Has the strength higher than that of plastic pipe, rigidity and impact resistance. ● The anti-corrosive surfaces have the corrosion resistance as high as plastic pipe. ● Operating temperature is high and heat conductivity coefficient is low, so insulation of outer wall is unnecessary in winter and no condensation will be formed in summer. ● The inner wall is smooth and free of any scale sediment, so the head loss is 30% lower than that of steel pipe. ● The technology to connect pipes by electric melting is mature, electric-melting joints are highly resistant to axial tension and multiple fittings of various specifications and varieties are available. ● It is convenient for transportation and construction because its weight is light. This pipe is high in general reliability. And, under normal circumstances, its service life is up to 50 years. ● It is the best substitute of galvanized pipe because it is low in cost, hygienic and non-toxic. 3.Product standard compliance Its hygienic indexes shall meet provisions in GB/T17219 “Standard for Hygienic Safety Evaluation of Equipment and Protective Materials in Drinking Water”. The product shall meet provisions in standard CJ/T189-2007. 4.Technical requirements The color is generally black and also can be decided according to mutual agreement of the supply and requisitioning parties. The internal and external surface of the pipe shall be smooth, may be have small pits and bumps formed during natural shrinking and be free of any bubble, crack, decomposition discoloration and obvious scratch. And, two ends of the pipe shall be cut flatly.
