Carbon steel lap joint flange is quite similar to slip-on flange. The main difference is that the bore of lap joint flange has curved radius so that lap joint stud-end can be housed on pipe. Lap joint flange is mainly used for pipe which needs to be dismantled frequently for inspection. Lap joint flange is not welded or fixed in any way. It is free to spin for proper alignment.
