Spiral Welded Steel Pipes

HASS produce and supply Steel or Carbon pipes, both seamless and welded, for different purposes: resistance to low or high temperatures, medium or high pressures, for industrial plant appliances, and also suitable for corrosive environments. Our Pipes fulfill the ASME, EN and PED conformity requirements. Hide Text We effect further tests on our products cooperating with certified laboratories and external licensed companies in order to grant the highest level of conformity to the technical specifications required by our customers.

Sheet deep well pipes are made of St 37 material in accordance with DIN 1700 norms. Sheet drill pipes are assembled by welding to each other. It is resistant to underground reactions (collapses). Although the pipe weights cause an axial stress during the well lowering, both the pipe and the welding structure are strong enough to meet these loads. HASS Sheet Drilling Pipes are made of material conforming to TSE standards with wall thicknesses of 4 mm - 5 mm - 6 mm and are TSEK certified. Hass bridge type filter pipes are used to take precautions against silty in silty lands. Hass manufactures fittings such as reduction and pump flanges for Hass Sheet Drilling Pipes.

Hass column pipes are hard and resistant to high impacts. Trapezoidal teeth are designed to carry high loads. Since it does not rot and does not rust, it has a service life of at least 50 years. Special gasket; It prevents leakage, reduces shaking and extends the life of the pipe. It provides 100% sealing at high pump pressure. Thanks to the smooth surface, the friction is reduced and the water flow becomes more efficient. PVC Column Pipes do not react in acidic and alkaline water. It is resistant to chemicals. PVC Column Pipes are hygienic

HASSPIPE produces a high quality range of PVC-U well casings and screens strictly in accordance with the Standard TS 11794 and ISO standarts, class I, II and III. The standard TS 11794 and ISO applies as well for raw materials and workmanship of pipes used in the manufacture of the casing and screen. There are three basic ranges - a standard range for shallow, medium well depth and a heavy duty, thick walled range for greater well depths. The casing and screens are made from 100% virgin unplasticized poly vinyl chloride compound and are coloured grey. They are supplied with a male pipe thread at the spigot end and a female pipe thread at the socket end. No re-worked material is used. The pipe is produced under ISO 9001:9002 Quality Management System. Screens can be supplied with either a plain or filtered surface. Slots are arranged vertically to improve the mechanical strenght of the screens and are designed to give open areas ranging
