Q: What are the different methods of joining steel pipes without welding?: There are multiple ways to connect steel pipes without welding. These include: 1. Mechanical Couplings: These couplings consist of two separate pieces that attach to the pipe ends and then tighten together. They provide a secure and leak-proof connection, eliminating the need for welding. 2. Threaded Connections: This method involves threading the ends of the steel pipes to create a male and female connection. The pipes are then screwed together using pipe threads, creating a strong and dependable joint. 3. Flanged Connections: Flanges are utilized to connect steel pipes by bolting them together. The flanges have a flat surface with holes that align with corresponding holes in the opposing flange. Bolts are inserted and tightened to establish a tight seal. 4. Grooved Connections: This technique involves grooving the pipe ends and using grooved couplings to join them. The couplings have teeth that interlock with the grooves, resulting in a secure and rigid connection. 5. Compression Fittings: Compression fittings are employed to connect steel pipes by compressing a metal or plastic ring onto the outer surface of the pipe. This creates a tight seal and a reliable connection without welding. 6. Adhesive Bonding: Special adhesives designed for bonding metals can be used to connect steel pipes. The adhesive is applied to the pipe surfaces, which are then pressed together and left to cure, forming a strong and durable bond. 7. Clamping: Clamps can be used to hold steel pipes together, creating a temporary connection. This method is commonly used for testing purposes or in situations where the pipes need to be easily dismantled. Each of these methods has its own benefits and limitations, and the choice depends on various factors such as the specific application, pipe material, and required joint strength.

Q: What's the difference between a rectangular tube and a rectangular steel tube?: Rectangular tube is a kind of hollow long strip steel, also known as flat tube, flat square tube or square flat tube (Gu Mingsiyi).
