REPAIR OF MAIN CYLINDER (CRACKS WELDING) OF HYDROSTATIC PRESS (WORKING PRESSURE – 150MPA.)

The isostatic press operating chamber is made as a hollow cylinder with a bottom. The force resulting from the operating pressure is withstood by the threaded bayonet connection.

THE REPAIR OF THE CHAMBER HAS INVOLVED THE  FOLLOWING OPERATIONS:

• examination of the chamber condition by nondestructive test methods to detect a defect zone;
• calculation of the stress-strain behavior of the chamber, selection of weld materials, and designing of the repair techniques;
• setting of the detected defect for furtherwelding;
• welding a joint;
• examination of the chamber conditions by nondestructive test methods of the repaired zone control.

SPECIFICATION:

•Operating pressure: 150 MPa;
•Dimensions: 800 х 1020 х 3557 mm;
•Weight: 13,000 kg.
