Lined J Type Dip Pipe & Drop Tube

PTFE Lined J Type Dip Pipe & Drop Tube

The PTFE Lined J Type Dip Pipe & Drop Tube is a precision-engineered process piping component designed for use in highly corrosive and chemically demanding environments. Manufactured by ADVECT Process Systems Canada Ltd., this product combines advanced lining technology with superior mechanical construction to ensure unmatched performance, safety, and durability in industrial operations.

At its core, the dip pipe is constructed from high-strength steel or alloy to provide mechanical stability under pressure and temperature fluctuations. The interior surface is lined with PTFE (Polytetrafluoroethylene) — a fluoropolymer renowned for its chemical inertness, low friction coefficient, and excellent resistance to thermal and mechanical stress. This lining ensures complete isolation between the process media and the metallic substrate, preventing any risk of corrosion, product contamination, or reaction with aggressive chemicals.

The J-type configuration is specifically designed for applications where the pipe must reach into the interior of tanks, vessels, or reactors to draw, transfer, or inject fluids efficiently. The curvature of the J design allows smooth fluid flow, minimizes turbulence, and ensures optimal drainage and mixing during operations. This makes it particularly suitable for processes involving acids, solvents, alkalis, and other hazardous fluids that require safe handling and controlled transfer.

ADVECT’s PTFE Lined J Type Dip Pipes are produced using precision forming and lining techniques that guarantee uniform lining thickness, excellent bonding, and resistance to mechanical wear. Every component is tested rigorously for leakage, pressure endurance, and dimensional accuracy, ensuring full compliance with international quality standards such as ASTM, DIN, and ISO specifications.
