BENEFITS
• Corrosion protected for offshore market by means of nickel plating.
• Easy to change wearing parts and easy to maintain.
• Quick adjustment to various tasks due to interchangeable shoes (serrated, stepped).
APPLICATIONS
Wedge spreaders can be used for: pipe and flange repair, removing of elbows, removing of couplers,
gasket and metal seals replacement, maintenance/replacement of valve and control equipment, general
spreading applications in the oil and gas industry, and general repair and maintenance.
OPERATING INSTRUCTIONS
FLANGE OPENING
• After loosening/removing flange bolts insert wedge spreader(s) at least up to the gripping surfaces of the
spreader shoes and gradually apply pressure via the pump. Maximum operating pressure is 700 bar
(10,000 psi). Visually check that flanges are seperating accordingly. At end of tool stroke insert stepped
block before gradually reducing pressure on the wedge spreader.
• Repeat previous steps until you reach maximum flange opening possible with inserted stepped block
(see fig. 2).
FLANGE CLOSING
• In order to close a flange you have to insert the spreader at ±80% stroke of tool. Take over the load from
the stepped block onto the spreader before removing said stepped block one step back. Gradually reduce
pressure to let the load be taken by the next smaller step of the stepped block.
• Repeat previous steps until you reach full flange closing. Replace and tighten flange bollts.
