Diplast Solvent Cement

DIPLAST is leading manufacturer to produce reliable solvent cements for use with PVC & CPVC Pipe & fittings.
Each formulation has been developed for a specific application and is subject to the strictest quality control program.
in the industry. This program guarantees the most consistent and highest quality solvent cements commercially available.

Description

To make consistently good joints, the following points should be clearly understood:-

  • 1. Check the pipe & fitting for dry fit before cementing. For proper interference fit, fitting should go over end of pipe easily but become tight about1/3 to 2/3 of the way on. Too tight a fit is not desirable; you must be able to fully bottom the pipe in the socket during assembly. If the pipe and fitting are not out of round, a satisfactory joint can be made.
  • 2. The joining surfaces must be softened and made semifluid.
  • 3. Sufficient cement must be applied to fill gap between the pipe & fitting.
  • 4. Assembly of pipe and fittings must be made while the surfaces are still wet and cement is still fluid.
  • 5. Joint strength develops as the cement dries. In the tight part of the joint the surfaces will tend to fuse together in the
    loose part, the cement will bond to both surfaces.

Jointing Procedure for DIPLAST PVC PRESSURE PIPES

Procedure for cutting of pipe and application of solvent cement The professional installer should be able to successfully assemble Rigid PVC Pipe and fittings by following The Diplast solvent cementing with primer instructions listed below:

  • 1. As pipe diameter increases ,so does the difficulty in installing it
  • 2. Use of proper size applicator Brush is even more necessary to ensure enough cement is applied to fill the larger gap that exists between the pipe and fittings.
  • 3. End of pipe must be cut square and chamfered.
  • 4. Clean the pipe properly before applying solvent cement.
  • 5. Increase size of joining crew:-

4’’-6’’ : 1-2 Persons
6’’-8’’ : 2-3 Persons
10’’-12’’ : 3-4 Persons

  • 6. It is important in large diameter jointing that the primer and cement be applied simultaneously to the pipe and fittings.
    Make sure to apply a second, full layer of cement to the pipe.
  • 7. Large diameter pipe and fittings require longer set and cure times. *(in cold weather, a heat blanket may be used to
    speed up the set and cure times).
  • 8. If pipe is to be buried , make as many joints as possible above ground, then after joints have cured, carefully lower
    into trench. Never bury empty cans, brushes cans or anything else containing wet cement, primer or cleaner next
    to the pipe.
