Detailed Description for PVC Solvent cement

Solvent cement joining always involves a pipe or tube end and fitting socket or pipe bell. The inside of the socket is slightly tapered, from a diameter slightly larger than the pipe OD at the entry, to a dimension at the base of the socket that is a few thousandths of an inch smaller than the pipe OD. Thus, the pipe-to-socket match-up results in an interference fit more-or-less midway in the socket.

Solvent cement is applied to the outside of the pipe end and the inside of the socket. The pipe is then pushed into the socket until it bottoms. Some codes require a primer to be applied before the solvent cement.

 

Pipe and fittings are bonded together by means of chemical fusion. Solvents contained in primer and cement soften and dissolve the surfaces to be joined. Once the pipe and fitting are assembled, a chemical weld occurs. This weld strengthens over time as the solvents evaporate.

 

The solvent-cemented connection in thermoplastic pipe and fittings is the last vital link in a plastic pipe installation. It can mean the success or failure of the system as a whole. Accordingly, it requires the same professional care and attention that are given to other components of the system. There are many solvent cementing techniques published covering step by step procedures on just how to make solvent cemented joints. However, we feel that if the basic principles involved are explained, known and understood, a better understanding would be gained as to what techniques are necessary to suit particular applications, temperature conditions, and variations in size and fits of pipe and fittings.

To consistently make good joints, the following should be carefully understood:

 

  1. The joining surfaces must be softened and made semi-fluid.
  2. Sufficient cement must be applied to fill the gap between pipe and fitting.
  3. Assembly of pipe and fittings must be made while the surfaces are still wet and fluid.
  4. 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.

 

FEATURES:

1. Easy to use,

2. Quick positioning,adhesive strength, curing the advantages of non-toxic materials. 

3. After bonding water, heat, cold, oil, corrosion resistance.
