Document Type and Number:
Japanese Patent JPH07132313
Kind Code:
A
Abstract:

PURPOSE: To efficiently perform descaling and coating of a lubricant on the inside surface of a tube immediately before an elongating process or reeling process for manufacturing a stainless tube.

CONSTITUTION: The inside surface of a tube is descaled by using high pressure water, and simultaneously coated with a lubricant by ejecting the powdery lubricant in the direction reverse to the ejection of the high pressure water. At this time, a gas is blown in from a nozzle 5 provided between the ejection nozzle 3 of the high pressure water and the ejection nozzle 4 of the lubricant so that the inside of the tube is kept in a positive pressure.
