Hydraulic Bulging: Hydraulic bulging of welded tees is a forming process that uses axial compensation of the metal material to bulge out the branch pipe. The process involves using a specialized hydraulic press, injecting liquid into a pipe blank with the same diameter as the welded tee. Two horizontal side cylinders of the hydraulic press move synchronously to compress the pipe blank. As the pipe blank is compressed, its volume decreases, and the pressure of the liquid inside increases. When the pressure reaches the level required for the branch pipe to bulge out, the metal material flows along the mold cavity under the combined action of the side cylinders and the liquid pressure inside the pipe blank, thus bulging out the branch pipe. The hydraulic bulging process for welded tees can be completed in one step, resulting in high production efficiency; the wall thickness of the main pipe and shoulder of the welded tee is increased.

Monel 400 Introduction
Monel 400 alloy (UNS N04400/MCu-28-1.5-1.8/Ni68Cu28Fe) is a nickel-based alloy, primarily composed of nickel-copper alloy, with a melting point of 1300-1350°C. It exhibits good corrosion resistance in corrosive media such as seawater, hydrofluoric acid, and sulfuric acid. This alloy demonstrates stable mechanical properties and is suitable for working environments ranging from low to high temperatures. Welding can be performed using TIG, MIG, and manual arc welding, matched with Monel body material or EniCu7 welding consumables. This alloy is mainly used in the manufacture of heat exchange equipment, chemical pipelines, reaction vessels, and other devices, conforming to standards including ASTM B 164 (bars) and ASTM B 127 (plates). During machining,shrinkage allowance must be allowed to ensure dimensional accuracy. This can be achieved through traditional machining methods; however, high-speed machining requires the use of water coolant.Cross Tee Introduction
Welded tees are pipe fittings used at pipe branches. For manufacturing welded tees using seamless pipes, the commonly used processes are hydraulic bulging and hot pressing.
Hydraulic Bulging: Hydraulic bulging of welded tees is a forming process that uses axial compensation of the metal material to bulge out the branch pipe. The process involves using a specialized hydraulic press, injecting liquid into a pipe blank with the same diameter as the welded tee. Two horizontal side cylinders of the hydraulic press move synchronously to compress the pipe blank. As the pipe blank is compressed, its volume decreases, and the pressure of the liquid inside increases. When the pressure reaches the level required for the branch pipe to bulge out, the metal material flows along the mold cavity under the combined action of the side cylinders and the liquid pressure inside the pipe blank, thus bulging out the branch pipe. The hydraulic bulging process for welded tees can be completed in one step, resulting in high production efficiency; the wall thickness of the main pipe and shoulder of the welded tee is increased. Hot Press Forming: Hot press forming of weld neck tees involves flattening a tube blank larger than the diameter of the weld neck tee to approximately the diameter of the tee, and opening a hole at the branch pipe section. The tube blank is heated, placed in a forming mold, and a punch for stretching the branch pipe is inserted inside the tube blank. Under pressure, the tube blank is radially compressed. During the radial compression process, the metal flows towards the branch pipe and forms the branch pipe under the stretching of the punch. The entire process is formed through the radial compression of the tube blank and the stretching of the branch pipe section. Unlike hydraulically bulged weld neck tees, the metal of the branch pipe in hot-pressed weld neck tees is compensated by the radial movement of the tube blank, hence it is also called a radial compensation process. Because the weld neck tees are formed by pressing after heating, the tonnage of the equipment required for material forming is reduced.
