Well drilling - Import export

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.
