lap joint flange is the use of flanging, steel ring and other flange on the pipe end, the flange can be moved on the pipe end. The steel ring or flange is the sealing surface, and the flange is used to hold them down. It is easily to find that the lap joint flange is not indirectcontact with the medium because it is blocked by the steel ring or flanges.That is why they are called lap joint flange or loose-sleeve flanges.
lap joint flange are suitable for the connection of steel, aluminum and other non-ferrous metals and stainless acid-resistant steel containers and corrosion resistant pipelines.
lap joint flange is a movable flange piece, which is generally matched with water supply and drainage fittings (expansion joint is the most common).So for finished flanges, there is a flange at both ends of the expansion joint, which is directly connected with the pipeline and equipment in the project with bolts.
You know, the flange with the looper. It is usually used on pipes, so that the live bolt can rotate the pipes on both sides and tighten them. It can be more convenient to disassemble and install pipes. lap joint flange are also called loose flanges.
1. The raw materials from well-known manufacturers such as Bao Steel and Baotou Iron and Steel are selected to ensure product performance. The raw materials are inspected firstonceentering the factory, and the samples are produced before mass production.
2. Using the forging process, the round steel after forging will improve the mechanical properties of the metal, improve the internal organization of the metal,andthe bearing capacity is stronger, stability is better.
3. CNC lathe processing, accurate size,with enough material, product surfacewill bebright,withoutscratches.
4. Company name, specifications, furnace number and other informationwillbe markedon each product, and every process of the product can be traced back.
