Rubber adhesive for connection. Shake well before use. The steel plastic pipe and socket parts must be clean, socket gap as small as possible with cloth or saw a hair surface, socket is thinly uniform brush glue, socket position of the outer brush two times after the glue dry glue, 40 ~ 60s after insertion in place, should also pay attention to climate change according to the appropriate adhesive dry time.
Water is prohibited when bonding, the pipeline must be placed in the trench in place, to be dry after the joint 24h backfill, backfill will fill tight around the pipe with sand, then a large number of joints for backfill. To use the same manufacturer's products. UPVC pipe and steel pipe is sheathed, must be at the joint of the steel tube wipe glue, U PVC tube heating become soft (but not burnt) after the socket on the steel pipe and cooling treatment, such as with the hoop will be better.
A large area of the damaged pipe needs to replace the whole section of the pipe, can be used to replace the pipe fittings of the two way. Solvent treatment can be used to deal with the leakage of the solvent. At that time, the water in the pipe is drained, and a negative pressure is formed in the tube, and then the adhesive is injected into the pores of the leakage part. Because of the negative pressure in the pipe, the adhesive can be sucked into the pores to achieve the purpose of leakage prevention. The method is mainly aimed at the leakage of the pipeline through small holes and joints.
At this time the selection of 15 to 20cm of the same diameter of the pipe, its longitudinal cut, according to the method of adhesive joints of the casing and the inner surface of the pipe to be covered with hair, after the glue coated in the water tight. Glass fiber method is the use of epoxy resin and curing agent into the resin solution, with a glass fiber cloth impregnated resin solution, the uniform winding in the pipeline or joint leakage at the surface, after curing. Because the method has the advantages of simple construction, easy mastering technology, good plugging effect and low cost, has very high application value in the anti-seepage and mending leakage in.
