Geothermal Wellhead Project

Douson designed and manufactured a geothermal wellhead for Kenya Electric Heating Company, which is used to exploit underground water vapor. The high-temperature and high-pressure steam medium is accompanied by a small amount of sand and a certain amount of sulfide, and the temperature of the wellhead medium is as high as 400°C.

According to customer requirements, the equipment is equipped with only one main valve (generally two), which puts forward higher requirements for the reliability of the main valve. Douson adopts higher standards in material selection, product sealing and product connection processing. Level, so that the equipment can fully meet the customer's on-site use requirements.
