PP Piping Systems Solve Corrosion Problems in Steel Manufacturing Plants
A polypropylene (PP) piping system used for a steel mill’s acid recovery and acid regeneration lines.

Steel mills are becoming increasingly automated and they employ a variety of piping products to provide strict control and safe conveyance of process solutions, many of which are highly corrosive, in the most efficient manner possible. Read about a large steel mill plant in Mexico, which switched its metal piping system to a polypropylene (PP) system due to the metal pipes’ extremely short service life. Learn more.

Pharmaceutical Plant Improves Production by Revamping Purified Water System

A pharmaceutical facility in Germany, which manufactures oral pills for the European and domestic markets, faced such product success that the production utilization was near capacity. In order to meet market demand, a concept was conceived to optimize production while maintaining actual GMP (good manufacturing practices). To achieve the required plan, production had to be relocated along with the supporting processes. The existing purified water (PW) system, installed with a PVDF (polyvinylidene fluoride) piping had performed to specification but would need to be modified in order to supply the necessary water quality to the new location and ensure a successful and timely installation. The scope of the project called for an expansion of the existing system while maintaining purity and integrity features. Find out how this project was accomplished.

Technical Advisory: Polypropylene (PP)

Polypropylene (PP) offers a good balance of thermal, chemical and electrical properties with moderate strength. It possesses a good strength to weight ratio. Because it has such a hard, high gloss surface, polypropylene is ideally suited to environments where there is concern for bacteria build up that can interfere with flow.

Polypropylene has good insulating properties. Its excellent arc resistance and dielectric strength allows polyprolylene to be used extensively in elextrical application. It can also be modified to be conductive or antistatic.

Plastics are the perfect lower-cost alternative to other materials in power plant operations. They stand up well to heat, pressure and chemicals, providing a nearly maintenance-free solution to any harsh environment.

Did you know that the global cost of metallic corrosion in 2010 was US$15 trillion (10 trillion Euro)?
