Galvanised steel
Athi Steel provide special job galvanising and also manufacture galvanised pipes (water pipes). Other galvanised products include, telecommunication and electrification transmission towers, fasteners, hot-rolled structural steel etc.
Athi Casing – The Heart of the Well
Casing is large diameter pipe that is assembled and inserted into a recently drilled section of a borehole and typically held into place with cement.Purpose Casing that is cemented in place aids the drilling process in several ways: i. Prevent contamination of fresh water well zones. ii. Prevent unstable upper formations from caving-in and sticking the drill string or forming large caverns. iii. Provides a strong upper foundation to use high-density drilling fluid to continue drilling deeper.Sizes Available – 4″, 6″, 8″, 10″
