Boiler Pressure Vessel And Pressurized Piping Vessel


This Policy is extended to include damage as specified below to boilers and pressure vessel plant.

Damage caused by their own Explosion or Collapse.

Explosion shall mean the sudden and violent rending of the permanent structure of the plant by force of internal steam or fluid pressure or bodily displacement of any part of such structure together with forcible ejectment of its contetns, except in the case of a steam test at a pressure not exceeding the maximum pressure permitted by the inspecting authority the term explosion shall not mean failure under any test.

Collapse shall mean the sudden and dangerous distortion of any part of the permanent structure of plant by bending or crushing caused by force of steam or fluid pressure whether attended by rupture or not. Except in the case of a steam test at a pressure not exceeding the maximum pressure permitted by the inspecting authority the term collapse shall not mean failure under any test.

The following defects do not constitute explosion or collapse even though repair or replacement may be necessary :

wearing away or wasting of the material of the plant whether by leakage, corrosion or by the action of the fuel or otherwise;
slowly developing deformation or distortion of any part of the plant;
cracks, fractures, blisters, laminations, flaws or grooving even when accompanied by leakage or damage to tubes, headers or other parts of the plant caused by overheating or leakage at seams, tubes or other parts of the plant;
failure of joints;

but explosion or collapse arising from any such defect is not excluded hereby.

Exclusion to this Extension :

Damage arising during the application of hydraulic test of the plant and occasioned thereby.

Definitions :
THE TERM BOILER AND PRESSURE VESSEL PLANT INCLUDES ANY CONNECTED SUPER HEATERS, ECONOMISERS, MOUNTINGS, FITTINGS, VALVES AND STEAM PIPING.

Specific Exclusions to this Extension :

If at the time of explosion or collapse or other damage insured by this extension :

the load on the safety valve or safety valves upon the particular item of plant was in excess of that permitted by the latest certificate issued in accordance with Boiler Inspection Regulations applicable thereto; or,
if any safety valve limiting the pressure is removed or rendered inoperative; or,
where certificates of inspection are issued by a Government Department if the particular item of plant was not so certified –

the the Insured shall not be entitled to any indemnity under this Extension.
