Combining the strength of steel with the corrosion resistance of plastics, these plastic lined steel products provide the best of both worlds.
Harrington carries the full line of DufLine Products
The handling of highly corrosive and hazardous acids and solvents has certain processing requirements. To meet these requirements, Harrington carries the full line of DufLine products.
Lined pipes and fittings are used in most Chemical, Petrochemical, Pulp and Paper Industry applications where hazardous acids and solvents are used in processing. Highly acidic and corrosive chemicals have a tendency to corrode and eat away non-lined steel piping. Lined piping systems are also used in the Food and Pharmaceutical Industry where the challenge is to maintain the highest levels of cleanability and durability.
Harrington has a complete line of pipe, fittings, valves and expansion joints with a variety of flanges and finishes. For questions regarding lined steel piping products, fill-in the contact form or call 1-800-213-4528.

Combining the strength of steel with the corrosion resistance of plastics, these plastic lined steel products provide the best of both worlds. Due to the inertness of PTFE to almost all chemicals and solvents, it acts as an effective barrier between the chemical and steel, not only protecting the conveying system, but also safeguarding the working environment. Corrosion engineers realize the long-term benefits associated with using high performance fluoropolymers to prevent corrosion in process piping systems. Lined systems are abrasion and wear resistant while maintaining non-stick and high purity characteristics.
A wide variety of chemicals can be used through a lined system, making it more versatile and economical for the long term. Due to the absence of corrosion, the life of the pipeline systems increases. PTFE lining safeguards and enhances better working conditions, reduces repair time and minimizes maintenance costs. Harrington carries a full line of plastic lined steel products available from 1″ to 12″ with PTFE, PP, PVDF or PFA liners and casing pipe of cast steel, stainless steel, or ductile iron.
