Pennar Industries Limited is one of the leading engineering organisations in India. Their tubes division, based in Hyderabad, rollforms ERW tube for use in precision tube applications. Pennar was using a leading competitor’s coolant but experiencing corrosion within two days of forming and undesired dirtiness and oil carry-over into their annealing process, resulting in black spotting.
Metalube® recommended Cool-Tek™ 250 as a cleaner alternative with higher levels of corrosion protection.
The carefully selected additives in the Cool-Tek™ range provide effective lubrication, excellent fines handling, superior cleanliness (resulting in extended roll/tool life), excellent surface finish, and corrosion protection.
Cool-Tek™ 250 was initially placed in one mill rolling tube from hot rolled, low carbon steel.
Pleased with the results after six months, Pennar subsequently implemented Cool-Tek™ 250 in more of their mills producing large diameter tubes.
Cool-Tek™ application at Pennar achieved:
