in larger pipes the main sections are factory lined. The joints are often buttstrap. After the joint is welded, some lucky soul gets to crawl up the pipe with a bucket of cement mixture and hand render the joint. Sometimes a manhole is let into the pipe. On pipes too small to crawl up I normally use flanges, but a sacrificial sleeve and pressure grouting from the outside could be easily arranged, as can a pressure bag if there is access from one end. Its just a cost thing; flanges can be very expensive and are a potential leak point. One cement lined steel pipe I know of (seawater) uses gibaults and has lasted 30 years, with the usual leaks, but the pipe ends have lasted which surprised me.

Mate, we can do anything! Sometimes it even works.

Cheers

Steve

I'm no expert on this matter, but how is the lining put into the pipe if the sections (including the lining) are not manufactured in a plant?

Sliplining is possible now, but was it then?
