Project Description


Marvel Technoplast Pvt. Ltd. proudly introduces Flowguard Plus Hot & Cold water piping systems into Nepal under license from The Lubrizol Corporation, USA. Lubrizol is a single-source provider of polymer technologies designed to solve today’s toughest building and production challenges, and is a innovator and world leader in chlorinated poly vinyl chloride (CPVC) Resins and compounds. Lubrizol’s history of providing superior piping solutions for residential, commercial and industrial applications dates back to 1959 when Lubrizol’s (formerly BF Goodrich Performance Materials) pioneered chlorinated polyvinyl chloride (CPVC) for use in piping systems. Their high performance and low combustibility CPVC technology is backed by robust research and development capabilities. This high-performance piping system is the most widely used CPVC plumbing system in the world. Made by the industry-leader in CPVC, Lubrizol’s products boast more than 50 years of field use.

The pipes manufactured with Lubrizol’s compounds are specially formulated, tested, and proven to maintain water purity, resist corrosion, and last longer than generic CPVC products. They provide exceptional corrosion resistance for hot and cold water plumbing applications, are easily installed using reliable solvent-welded joining techniques and offer quality, cost-effective choice for long-term system service. Further Marvel is the only company in Nepal which has taken internationally acknowledged NSF certification for CPVC pipes to ensure that the products are hygienic and meet strict international performance parameters. Marvel FlowGuard Plus pipes & fitings are made from a specialty plastic known chemically as chlorinated poly vinyl chloride (CPVC). This compound meets cell class 23447 B as defined by ASTM D 1784 and has a design stress of 2000 PSI and a maximum service temperature up to 93 degree C.
