In municipal water supply and drainage pipeline projects, ductile iron pipes have become the material of choice due to their outstanding strength and corrosion resistance. The unique design of the T-joint provides the pipeline system with a℃of "flexibility"-it can be installed with bends within a specified angle. This characteristic significantly enhances the adaptability of pipeline laying and construction efficiency. Today, we will delve into the bending installation techniques for T-joint ductile iron pipes.

T-type joints, also known as slip-fit flexible joints, are characterized by their rapid installation requiring only basic tools. Their core advantage lies in the specialized seal ring design and socket structure, which permits angular deflection at pipe connections without compromising sealing performance. This allows deflection of the entire pipeline by accommodating deflection in each individual pipe section.

 

T-joint ductile iron pipes cannot be arbitrarily bent. When pipe deflection is required, it can be achieved by deflecting the pipe at the joint within the permissible angular deflection range.
In actual engineering projects, the construction deflection angle typically does not exceed 75% of the design-allowed value to ensure a safety margin. Through the cumulative effect of deflection at multiple joints, the pipeline system can achieve significant angular changes in direction, meeting the requirements for curved pipeline layouts.
By reasonably utilizing the deflection angles allowed at the joints, installers can flexibly adapt to complex terrain and spatial constraints while ensuring the sealing integrity and strength of the pipeline system.
