Water Pipe Infrastructure The PROBLEM - Outdated Iron Pipe Systems Corroding Water Quality· Water delivery and sewage treatment are critical to public health and the environment. Corrosion, leaks and breaks in old-technology pipe materials are degrading our drinking water and wastewater systems.· The burden of corrosion-prone pipe materials is not limited to the cost of repairing and replacing failed pip…
Sustainable Water Infrastructure with PVC Pipes Sustainability is the capacity to endure. In large measure, the longer something lasts, the more sustainable it is. PVC and similar materials are 30 – 70% less expensive easy to install, environmentally friendly, noncorrosive and durable with an expected design life of more than 100 years without the extensive and expensive corrosion treatments needed for more traditional pipe …
Corrosion Resistance of PVC Pipes The major finding of a recent study is that PVC Pipe has the lowest overall failure rate when compared to cast iron, ductile iron, concrete, steel, and asbestos cement pipes. The report concluded that corrosion was a major cause of water main breaks. Escalating deterioration of water and sewer systems due to corrosion, leaks, and breaks in old-technology pipe materials threaten …
Strength & Durability of PVC Pipe PVC Pipes are strong and durable despite their relatively low weight. This makes PVC Pipes suitable for all types of long-term applications including domestic water, sewerage, stormwater, and deep underground piping systems. It stays strong through a range of temperatures resulting in fewer burst pipes and other maintenance issues. PVC-O PIPES ARE TOUGHER THAN THEIR DUCTILE IRON…
Applications of PVC pipe - Large Diameter PVC-O Pipes-2 When PVC-O Pipe is used for high pressure pipelines they have a number of performance and environmental benefits compared to alternative products. The pipe is highly energy-efficient and environmentally-friendly during all its useful life because of the considerable savings in raw material. DN600 PVC-O Pipe will be less than half the weight of PE and one third of the weight of e…
Applications of PVC pipe - Large Diameter PVC-O Pipes-1 The new release of PVC-O Pipe with diameters up to DN 600mm make them the best solution for medium and high pressure networks for potable water supply, sewer rising mains, recycled water systems, sewer rising mains, irrigation systems, and pumping systems. PVC-O Pipes are the most advanced pipes for the conveyance of high pressure water on the market. The process of molecular or…
Applications of PVC pipe - Coal Seam Gas Coal seam gas production is water hungry business. Millions of gigalitres of water are brought to the surface, removed from the coal seam in order for the gas to be extracted. Conservative estimates suggest coal seam gas wells could draw 300 gigalitres of water from the ground each year from the some 40,000 coal seam gas wells estimated for Australia. Once the water is brought t…
Benefits of PVC Pipes-2 Coefficient of FrictionWhen piping systems are designed one of the main concerns is flow rate and pressure. PVC Pipes provide smoother wall surfaces that reduce fluid friction and resistance to flow. This hydraulic smoothness inhibits slime build-up in sewers and virtually eliminates tuberculation and encrustation in water distribution mains. The end results are significantly lo…
Benefits of PVC Pipes-1 PVC Pipe is a product of modern technology that offers reliable and durable service to a variety of users including contractors, engineers, operators, industries, utilities, and irrigation districts. A number of performance advantages means PVC Pipes now replace many traditional materials. Lightweight
Innovations and Advances in PVC Technology-2 In the PVC market there’re some companies who developed a renewable modifier for PVC that increases the strength and resists fungi and biodegradation. PHA (polyhydroxyalkanoate), a biobased copolymer, offers improved processing with all PVC compounds. While the PHA polymer is biodegradable, when used in a non-biodegradable polymer, the biodegradation process is not increased. T…
Innovations and Advances in PVC Technology-1 PVC PipePVC pipe is approximately 75% less expensive in use than PE pipe, (polyethylene HDPE). New advancements include PVC-O, oriented PVC and PVC-M, modified PVC. PVC-O has been successfully used in Australia for almost 20 years. This pipe is produced by re-aligning the molecules in PVC with Biaxial orientation. The pipe produced is considerably stronger, allowing the wall th…
PVC Heat stabilizers for medical applications-3 The inorganic stabilizers are mainly acid scavengers that restrict the release of toxic gases such as hydrochloric acid and organic co-stabilizers are used to improve the color hold and UV stability of the final product. Along with these stabilizers, many processors also use Epoxidized Soya-Bean Oil (ESBO) in the flexible compounds to improve heat stability and UV resistance of …
PVC Heat stabilizers for medical applications-2 Single-use medical applications of PVC like gloves, masks, sterile syringes, blood bags, IV bags, tablet packaging, are a game-changer. Sanitization is a constant challenge in front of medical workers and historically multi-use medical devices were the main reason behind infections due to cross contaminations. Moreover, traditional sterilization facilities such as the use of eth…
PVC Heat stabilizers for medical applications-1 The pandemic has changed the world in many ways like never before. But there is a silver lining. Plastics have gained great respect in society in general thanks to the contribution of PPE kits and medical devices in the fight against Covid-19. Plastic has been the undoubted hero in this battle that protected frontline workers as a shield and helped to cure patients in the form o…
Functions and Dosage of various PVC Lubricants-3 It is desirable to know how important lubricants are, but it is critical to know how much to useUnder lubrication or over lubrication affect the processing as well as product quality. Under lubrication will result in frictional heat and degradation of PVC or poor fusion with loss of mechanical properties. Over lubrication is a problem that results in scorching, low output, surg…
Functions and Dosage of various PVC Lubricants-2 3. Fischer Tropsch WaxFischer Tropsch synthetic wax has a linear structure which gives high-temperature resistance, lower viscosity and softening points between 65-105°C. It increases the fusion time and stability of PVC while decreasing the fusion torque required for the processing of PVC. Its linear structure provides an excellent metal release effect and reducing the form…
Functions and Dosage of various PVC Lubricants-1 Lubricant is one of the most essential additives after heat stabilizer yet most difficult to adjust for the processing of rigid PVC. PVC requires various additives to prevent PVC from degrading when heated and sheared and get the desired and perfect articles. Lubricant reduces various types of frictions within the polymer matrix and between the polymer matrix and processing equi…
Heat Stabilizers for PVC: A complete guide-3 Lead-based StabilizersLead-based stabilizers offer the best electrical properties. This is stated by and large by the fact of the insolubility property of lead chlorides formed during stabilization. The Lead-based One Pack Stabilizers have a proportionate combination of Lead Stearate, Dibasic Lead Stearate, and Lubricants that give synergistic effects. The diligently manufacture…
