PVC PIPES

Polyvinyl Chloride (PVC) Pipes

Description

PVC is one of the specified thermoplastic for piping system components, including valves, fittings, flanges and many speciality products. PVC has excellent chemical and corrosion resistance to a broad range of fluids.

ASTRAL uPVC materials conform to ASTM Cell Classification 12454-B of ASTM D1784 (formally designated as Type I, Grade I ). The maximum recommended service temperature of PVC products is 60°C (140°F)

Pipe

PVC makes a major contribution to the quality , safety and cost-effectiveness of construction materials, as well as helping to reduce the environmental impact of completed projects. PVC is the most widely used polymer in building and construction applications and over 50 percent of Western Europe’s annual PVC production is used in this sector. PVC has a versatility that helps to meet modern and future design needs.

ASTRAL Aquarius uPVC solvent joint plumbing system makes its pressure bearing capacity twice than that of the threaded pipe.

BASIC USE

ASTRAL Aquarius uPVC pipes & fittings exhibit the wellknown physical characteristics and other benefits of conventional uPVC piping such as good chemical and corrosion resistance, low thermal conductivity, high strength-to-weight ratio, good impact resistance and ease of installation.

SYSTEM DESIGN

System design shall be in accordance with standard industry practice for thermoplastic industrial piping systems and shall take into consideration such factors as pressure and flow requirements, friction loss, operating temperatures, support spacing, anchoring, bracing and thrust blocking, temperature correction factors, joining methods, chemical environment, collapse and loading, and thermal expansion and contraction.

Key Properties

  1. ASTRAL Aquarius Lead Free Plumbing System is tough, durable with high tensile and impact strength. The system is light in weight and can be transported easily from one place to another .
  2. ASTRAL Aquarius Lead Free pipes can be cut, shaped, welded and jointed easily .
  3. ASTRAL Aquarius Lead Free Plumbing System is inherently difficult to ignite and stops burning once the source of heat is removed. Compared to its common plastic alternatives PVC performs better in terms of lower combustibility , flammability , flame propagation and heat release. Newly developed advantages in terms of lower acid emissions, smoke generation and enhanced fire resistance.
  4. ASTRAL Aquarius Lead Free Plumbing System is durable and free from weaknesses caused by rusting, weathering and chemical action and hence last for life time
  5. ASTRAL Aquarius Lead Free Plumbing System can be used in sunlight exposed conditions. However , ASTRAL recommends a standard grade of exterior latex paint (water base) which will protect the system adequately
  6. Jointing can be done speedily with special IPS solvent cement supplied by the company which ensures 100% leak proof joints
  7. ASTRAL Aquarius pipes are non-toxic and lead free which makes them a safe material for potable water . It is also the world's most researched and thoroughly tested material for PVC which meets all international standards for safety and health for both the products and applications
  8. Smooth inner surface ensures high flow rate and low friction losses. The system is leach and scale free.
  9. PVC does not conduct electricity . ASTRAL Aquarius pipes are non conductor of electricity so it make the plumbing system safe when working with electrical tools or equipments.
  10. uPVC is generally inert to most mineral acids, bases, salts and paraffinic hydrocarbon solutions. For more information on uPVC chemical resistance refer to Chemical Resistance of Rigid Vinyls Based
  11. ASTRAL Aquarius Lead Free Plumbing System available from ½" (15 mm) to 12" (300 mm) with wide range of fittings, transition fittings, valves and specially designed brass inserted fittings to suit any design criteria.
