We are able to supply a variety of pipes appropriate for both suction and delivery of water for various purposes such as potable water, waste water or agriculture. The material of the pipes available is as follows:
– High Density Polyethylene (HDPE)
– PVC and UPVC Rigid
– Flexible PVC
– EPDM Rubber
– Galvanised Iron
Compared to other plastics, polyethylene has a good resistance to acids and caustic substances. It is also resistant to organic and inorganic solvents at a wide range of temperatures. It is, however, not resistant to strong oxidizing acids.
PE100 is preferred to PE80 due to its better strength and durability, higher operating pressures, lower sensitivity to surface damage during laying, and improved resistance to rapid crack growth. The higher strength of PE100 permits thinner pipe walls than PE80 for the same operating pressure. PE100 uses less polymer and provides for a larger bore and increased flow capacity for a given nominal pipe size. This can result in significant cost savings. PE100 is extremely crack resistant to -30C
Pipes are available in diameters ranging from 32mm up to 800 mm, in pressure ranges from PN6 to PN25 in PE100. The pipes can be assembled using compression coupling up to 125mm or fusion welding. The pipes are available in straight cut form of 6mtrs or 11.8mtrs or in roll form of 25 mtrs, 50 mtrs or 100 mtrs (depending on the diameter of the pipe).
PVC is commonly known as Polyvinyl Chloride and uPVC is known as Unplasticized Polyvinyl Chloride since no plasticizers are used in it. Both materials are generally used in construction for different purposes.
– PVC pipes are optimally used in residential and industrial discharge systems for soil, waste and vent applications.
– UPVC pipes are generally used for plumbing, water supply and for lowering jet pumps in the borewells.
Available in standard sizes from 19mm to 200mm in diameter. Other sizes are available. Pressure ranges from PN6 to PN16 in the uPVC pipes used for pressurised water systems. The waste pipes are normally beige/brown in colour and are not pressurised. Rigid pipes are normally available in 6 mtr lengths but other lengths may be available on request and depending on order size.
Flexible PVC hoses are appropriate for both suction and delivery.
Available roll lengths include 20, 30 and 40m.
PVC is cheaper and is also available in different qualities.
Stronger hoses are also available for intensive use or for use with specific liquids.
Specifications for suction hose (high-quality, fireman quality, PVC flexible spiralled):
– Heavy-duty PVC suction hose, reinforced with a hardened PVC spiral helix
– Smooth inner surface
– Both ends fitted with Storz couplings
– Temperature range: -25°C up to 60°C
– Operational pressure: min 3 bar, 6 bar for 20°C is better
– Resistance to vacuum at 20°C: 90%
EPDM (ethylene propylene diene monomer) is stronger than PVC, and is recommended for rough and long-term daily use. EPDM Hose is composed with EPDM rubber reinforced with polyethylene external spiral and textile fiber.
EPDM food grade flexible pipes are used to discharge or charge food liquids (oil, milk, beer, juice, wine,…)
The main characteristics of the EPDM pipes are:
DESIGN. The spiral increases the resistance to the abrasion, corrosion and weathering and provides
for easier drag.
COMPOSITION. It allows to be cut in any length.
STRENGTH. The textile fibers allow more resistance to high pressures.
TEMPERATURE. From -20ºC to +60ºC (until 100ºc for sterilization process with low pressure and short time).
LIGHTNESS. Easy to handle because of its lightweight.
FLEXIBILITY. Recovery of 90% of shape in case of flattening.
WORKING PRESSURE. Pipes are available with maximum working pressures between 5 – 8 bars only.
Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines. They can be plain or bevel ended depending on the application. These pipes are meant for the conveyance of water, compressed air and fluids. They are also used for water borehole casting pipes. They restrict the collapse of overburden soil. Slots are cut on the pipes for screening purposes depending on the application.
Available in standard sizes from 1/2 inch to 12 inch in diameters and pressure rating from Class A to Class C. Other sizes are available on request. The length of each pipe is normally 6 mtrs.
Various fittings are available in various sizes and in the materials for the pipe required (including GI, PPR, HDPE, brass, PVC). Fittings include:
– tee bends
– elbow bends
