In our coated pipe and joint systems, the inner wall of each pipe receives a specialized anti-rust spray coating. This protective layer forms a tight, durable bond with the pipe interior, ensuring it is not easy to peel or flake off. This meticulous treatment is key to creating long-lasting, corrosion-free pipes.


During the production of every complete lean tube for our tube and joint systems, a critical gas test is performed. High-pressure air is injected into the pipe interior via an air gun. This proces eliminates any missed welds or perforations, ensuring the structural integrity and safety of each pipe component.
The plastic coating on every coated pipe is applied with precise, even thickness. This ensures a perfect fit with metal pipeline joints, meeting the stringent assembly requirements for seamless tube and joint systems.


The metal joints feature long strip stiffeners—two at the head and two at the tail, arranged in a jagged, three-column pattern. This design significantly increases clamping and pulling force, ensuring the connections within your tube and joint systems meet all safety and reliability requirements.
The edges and acute angles of our metal joints feature a humanized arc structure. This thoughtful design protects both the product and user safety within your tube and joint systems.


Two clear assembly lines are marked on the tail of each metal joint. This design significantly improves assembly efficiency and prevents errors during the construction of tube and joint systems.
The planer pivot and bearing support of our aluminum roller track utilize T1.6MM and T2.5MM thick materials. This robust design meets stringent capacity requirements, significantly improving load-bearing performance to fulfill demanding needs in tube and joint systems.


The bearing support of our iron roller track features a substantial 15MM height. This design meets strict capacity requirements, ensuring the roller track delivers superior carrying performance for demanding tube and joint systems.
This design distributes weight evenly, improving the overall strength and stability of the roller track wheels. Its rolling contact mechanism is more wear-resistant than sliding contact, ensuring enhanced durability and a longer service life for your tube and joint systems and related accessories.


The roller track wheels adopt a double-bearing construction that enables greater load capacity and more flexible rotation. This design ensures smoother operation, enhances caster stability within tube and joint systems, and minimizes malfunctions from heavy loads or frequent movement.
