New movement on old pipes
The plumbing industry is launching product ranges designed to maintain the balance of nature.

One of the most popular pipes used for home supply are plastic plumbing ones. Their essence lies in the fact that they are light weight, chemically resistant, non-corrosive, and quite easy in making connections. Most manufacturers use a number of plastic materials for producing plastic pipes. Some of the most popular materials are polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC), cross-linked high-density polyethylene (PEX), polyethylene pipe (PE), polybutylene (PB), and acrylonitrile butadiene styrene (ABS).
Pankaj Soni, Victaulic country manager India, says, “Thin wall piping is an increasingly attractive option in construction markets for a wide variety of applications, including chilled water, hot water and potable water. And just like in Europe, there is a gradual increase in adoption as the material of stainless steel as the material of choice.”
Reduced pipe weights are easier to handle on job sites, improving safety and ease of installation, while stainless steel is more pliable and forgiving. It also offers excellent corrosion resistance. However, thin-wall piping does have disadvantages and there are challenges that face the industry. For example, highly skilled labourers are required as welding thin-wall is much more difficult than conventional welding.
Siddharth Bansal, director, Skipper Limited, says, “Over the last decade, one of the most important changes to have taken place in the piping industry has been the large scale shift from metal to polymer based pipes in most applications. This is specially true in case of the plumbing and piping applications in the construction industry. This evolution to polymer based systems has allowed for greater R&D into specialised products for specific applications with the development of polymers such as CPVC for hot and cold water plumbing, for fire fighting and for the transportation of industrial fluids. Skipper has also brought in one the most advanced CPVC piping system made from the raw material sourced from Sekisui of Japan.”
Another new development has been the introduction of newer plumbing systems such as the polybutylene system known as the Skipper Wavin Hep2o plumbing system. The product is ideal for hot and cold plumbing and has the most advanced joints and fittings range in the world today. For high end projects, this is the major choice.
Harsh V Agarwal, executive director, Oriplast Ltd, says, “We have introduced a superior range of CPVC pipes and fittings made with the most advanced international technology. Our CPVC pipes and fittings are made out of heat resistant, global standard high performance chlorinated polyvinyl chloride material. The main feature of this product is enhanced heat-resistance in addition to the basic mechanical and chemical properties of base PVC. CPVC can be used in a wide variety of applications including piping for hot and cold water supply lines and is ideal for both industrial and everyday life applications.”
He cites some of the advantages of the CPVC pipes and fittings: Very good mechanical characteristics even at a high temperature; outstanding chemical resistance; no support for microbial growth; smooth inner surface; exceptional flammability resistance; long service life, even under intense corrosive conditions; no electrochemical corrosion; simple installation using solvent cement; very low thermal conductivity; and no influence on drinking water.
In terms of advancements in piping systems being developed for various applications, Victaulic continues to innovate. Among its recent developments is Vic-Press, an innovative product offering a small-diameter solution for off-the-shelf stainless steel schedule 10S pipe. Thanks to continued investment in research and development, customers in a wide range of commercial and industrial markets can now rely on Victaulic as a single-source provider for all stainless steel pipe joining needs from 15mm to 600mm. Vic-Press offers increased strength and durability with improved flow characteristics compared to light-wall tube systems; safer, more efficient pipe assembly than welding, threading and flanging; and meets or exceeds industry standards.
One of the biggest changes coming about in the real estate plumbing sector is the fact that piping is no longer a low-involvement category product as it was a decade ago. Consumers are now demanding better products and newer plumbing systems for their homes and projects. This is a very good evolution as it will allow for quality players such as us to bring their products to the consumers. Considering the pressure on land bank in metropolitan cities as well as tier-I and tier-II cities, companies are seeing a boom of tall constructions across the country. Construction of such high rise buildings is made possible due to advancements in construction technology which has forced to change the design and layout of drainage systems. Looking at these trends of vertical growth of cities and premium architectural designs, demanding premium drainage systems having low noise properties, many pipe manufacturers have launched new products to meet demand.
Victaulic recently expanded its Vic-300 MasterSeal
butterfly valve line to include a stainless steel body option. The new grooved-end series 461 butterfly valve is designed for pressures ranging from full vacuum to 300 PSI/2065 kPa and for bi-directional dead-end services to full working pressure.
The stainless steel series 461 butterfly valve provides the same high level of reliability the industry has come to expect from Victaulic and is perfect for any application where corrosion is a concern. The stainless steel valve features a patented seat design, made popular by the Victaulic Series 761 butterfly valve, which assures full 360-degree sealing. The pressure-enhanced seat compresses to form a larger seating area as the pressure increases. The seat design also contributes to the low breakaway torque capabilities of the MasterSeal valve. The series 461 is available in 2 – 8”/50 – 200mm sizes with a variety of operators that include both lever handle and gear operator options. The valve is NSF Certified in accordance with ANSI/NSF 61 for cold +73°F/+23°C and hot +180°F/ +82°C potable water service and ANSI/NSF 372.
Skipper’s Bansal says that newer technologies are getting introduced regularly. Some of these are
DWC pipes (for non pressure fluid transportation)
PVC O pipes (for high pressure fluid transportation)
Composite pipes (using metals & polymer)
With development of newer products and technologies the various types of pipes inundating the market are bound to grow multifold.
