BW latrolet and elbolet are the key component in pipeline connection. The butt-welded inclined branch pipe platform has an oblique structure, which can accurately connect the branch pipes at a specific angle on the side of the main pipe to achieve fluid diversion. Its butt welding connection is firm, its sealing performance is excellent, and its pressure-bearing capacity is strong. The elbow branch pipe platform connects the branch pipes at the elbow to adapt to complex pipeline layouts and change the direction of the fluid. Both are made of high-quality steel and manufactured through strict processes. They are widely used in petroleum, chemical industry, electric power and other fields to ensure the safe and stable operation of pipeline systems.
