About PP Lined Pipes

We are offering highly durable and rigid PP Lined Pipes which is commonly used to make heavy duty flow channels for the transportation of high pressure fluids throughout the system. The outer body is fabricated by using best grade mild steel to enhance the strength and sturdiness. It is also provided with flanged ends to make rigid connection in between two pipes. The inner poly propylene lining of the offered PP Lined Pipes makes it suitable for acidic, neutral as well as alkaline systems.

Superior Corrosion Resistance and Longevity

These PP lined pipes are engineered for excellent chemical resistance, making them suitable for the transfer of acids, alkalis, brine, solvents, and industrial effluents. With an internal 3 mm virgin polypropylene lining fused and mechanically locked to high-grade MS pipes, the system provides a durable, corrosion-resistant solution, minimizing the risk of process contamination and extending service life.

Safe and Easy Installation

Installation is straightforward with a bolt-on system using high-quality flanged ends, eliminating the need for on-site welding. Preferred gasket materials such as PTFE or EPDM ensure effective sealing. This simple installation method reduces downtime and allows for easier future maintenance or replacement in diverse industries.

Robust Design for Versatile Applications

PP lined pipes are manufactured to meet ASTM, DIN, and IS standards with tolerance of 1 mm. The pipes withstand rated pressures up to 10 kg/cm, temperatures from -20C to +100C, and are UV-resistant and non-conductive for added safety. Their reliability and low-maintenance nature make them the first choice for chemical, pharmaceutical, and water treatment sectors.

FAQs of PP Lined Pipes:

Q: How are PP lined pipes installed, and what makes the process convenient?

A: PP lined pipes are designed for bolt-on installation using flanged ends and gaskets (PTFE/EPDM), eliminating the need for site welding. This makes the installation process quick, safe, and easily manageable for maintenance or future upgrades, reducing operational disruptions.

Q: What fluids and applications are PP lined pipes suitable for?

A: These pipes are ideal for conveying acids, alkalies, brine, salts, solvents, effluents, and various chemicals. They are mainly used in chemical processing lines, acid handling, pharmaceutical applications, water treatment, and process industries, thanks to their high corrosion resistance and chemical compatibility.

Q: What is the benefit of the 3 mm minimum PP internal lining?

A: The 3 mm thick virgin polypropylene lining provides a robust, chemical-resistant barrier that effectively shields the steel shell from corrosive substances. This enhances pipe longevity, reduces maintenance costs, and ensures process purity during fluid transfer.

Q: How is leakage prevented in PP lined pipes?

A: Leakage prevention is ensured through a hydrostatic test at 1.5 times the rated pressure. Additionally, the fusion-bonded and mechanically locked PP liner, combined with robust steel construction and precision gasket sealing, reliably prevents leaks during operation.

Q: When should PP lined pipes be chosen over unlined or partially lined pipes?

A: PP lined pipes should be selected whenever aggressive or corrosive chemicals are transported, or when process purity and long service life are essential. Their design provides superior resistance to most acids and bases, making them preferable for chemically demanding environments.

Q: What maintenance is required for PP lined pipes?

A: These pipes are designed to be low maintenance and easy to clean. The internal PP lining impedes scale formation and deposit build-up, significantly reducing downtime and frequency of maintenance compared to traditional metal pipes.

Q: Where are these PP lined pipes typically utilized?

A: PP lined pipes are commonly used in Indias chemical, pharmaceutical, water treatment, and process industries by manufacturers, suppliers, exporters, and distributors seeking reliable, long-lasting fluid handling solutions.
