The process is basically to clean the surfaces with an abrasive then with MEK. Both inner and outer surfaces are coated with a solvent cement. Solvent cement consists of 25% ABS dissolved in MEK. The female fitting has a taper at the end so that when the male component is insrted a tight fit is achieved. The joint has to be held for a while to secure a good fit. The benefit of the joint is that you dont need concrete thrust blocks as with rubber ring joints.

The attached procedure explains it in a bit more detail. The second paper I delivered to the Institution of Mechanical Engineers

In Australia & SE Asia lines for sea water are in Acrylonitrile Butadiene Styrene (ABS). Tyco (Eurapipe) manufature to DN 750 in rubber ring jointed or
chemicallly (solvent) welded. The ABS is not the same product as listed in ANSI
B 31.3. Its much tougher. Of course you would need to have a few lines to cater
for your flow.

The beauty of this material is that you dont get corrosion on the inside or the
outside. Its great for sea water , septic sewerage, slurries, acid sulfate soils, puire water (electronics & pharmaceuticals) etc. W ehave just commissioned a 100 million dollar sewage treatment plant up grade where there is
no ductile iron. All ABS or spiral wound stainless steel. I forget to mention it
is cost effective too!
