PURPOSE:To prevent a leak of corrosion liquid by covering the outer circumference of an actual tube with a cylindrical protector, and fitting one terminal of this protector around one connecting sleeve in a double cylinder shape so that it is relatively movable in the axial direction. CONSTITUTION:The outer circumference of the actual tube 1 is covered with the cylindrical protector 9. One terminal of the protector 9 is fitted around one conneting sleeve 5L in the double cylinder shape so that it is relatively movable in the axial direction. The other terminal of the protector 9 is fitted around the other connecting sleeve 5R in the double cylinder shape and fixed thereto in one body by a fixing means such as a bolt. Consequently, if the actual tube is broken, corrosion liquid spouting from the break place is collected in the protector to prevent its leak. |
