For contractors and engineers managing critical fluid transfer infrastructure, the integrity of pipe connections is non-negotiable, especially under high-pressure conditions. Asoe’s PILC Couplings are engineered specifically to meet this demanding standard, providing a reliable, secure, and leak-proof solution that simplifies installation without compromising performance.
Here is a detailed look at the design, structure, and superior benefits of our couplings.
The core value of the PILC coupling lies in its reliable, multi-part design which ensures the pipe liner is permanently locked into place, preventing movement, abrasion, and, most importantly, leakage.
The PILC coupling contains three distinct, engineered components that work together to create a robust seal:
Outer Flange Tube:
Material: Carbon Steel, coated with durable epoxy powder.
Function: This is the primary structural component, used to securely fix the entire PILC coupling assembly onto the host pipes.
Expansion Ferrule:
Material: Carbon Steel.
Function: The critical component for liner retention. It is used to prevent the pipe lining from slipping or moving due to pressure or thermal changes, locking it tightly to prevent abrasion.
Inner Pushing Tube:
Material: Carbon Steel or Stainless Steel (selected based on the media being transferred).
Function: This tube serves to fasten the pipe liners securely onto the flange tube, ensuring a smooth internal connection and seal.
Our couplings are designed to solve the most common pain points associated with high-pressure pipeline connections:
Secure Liner Lock: The reliable, multi-part design ensures the liner is locked tightly onto the PILC couplings with no leaking, even under extreme pressure.
No Flow Loss: The inside diameter of the inner pushing tube is precisely the same as that of the liners, ensuring no reduction in water flow capacity.
Zero Friction Loss: The connection point between the liners and the inner pushing tube is seamless, eliminating friction loss and maintaining the efficiency of the fluid system.
Easy to Install: Despite their complex and robust function, the couplings are designed for simple and effective installation by qualified contractors.
While it is possible to weld the PILC directly onto the host pipe, the use of flanges is highly recommended for creating adaptable and maintainable connection points.
Flanges are the ideal choice for the following connection scenarios:
To connect host pipes directly with PILC couplings.
To be used between PILC couplings and transition tubes (where the pipeline material or size changes).
To be used between host pipes and transition tubes.
