The Bulk AmphiBlast™ is a Pressurized Vessel. Propelled objects will cause serious injury or death.
Depressurize vessel before performing any maintenance. See Section 6.2.
For proper operation, maintenance should be performed with the assistance of a qualified serviceman.
8.1.
Blaster Pressure Vessel: The ASME Code is a standard covering materials, design, fabrication,
and installation. Vessel integrity subsequent to purchase is the responsibility of the owner
and/or user. At intervals required by state law and/or local authorities, the vessel should be
subjected to a hydrostatic test as described in the ASME Code, Section VIII, Division 1. Do
Not subject the abrasive blaster pressure vessel to a pneumatic proof test exceeding the
maximum allowable working pressure. In no case should the hydrostatic test pressure exceed
1.3 times the maximum allowable working pressure (MAWP) shown on the pressure vessel
nameplate (#24). Thoroughly clean and dry the vessel before re-assembly. Moisture or debris
left in vessel can cause equipment malfunction.
8.2.
Blaster Pressure Vessel: Any damage to an abrasive blaster can make it unsafe. Inspect the
exterior of the abrasive blast vessel weekly for corrosion, pitting, or other damage (i.e. dents,
gouges or bulges). If damaged, take out of service immediately and have it inspected and/or
repaired by a qualified facility. Contact Axxiom Manufacturing, Inc. for technical support.
8.3. Blaster Pressure Vessel: The interior condition of the abrasive blast vessel (#1) should be
inspected quarterly. Pitting caused by corrosion will reduce the wall thickness of the vessel. If
excessive corrosion is found, have the abrasive blast vessel inspected by a qualified facility.
Contact Axxiom Manufacturing, Inc. for technical support. Refer to the ASME Data Report for
the vessel minimum thickness.
Check the pressure vessel internal piping for corrosion, cracks, wear, holes, or any other
damage. Repair or replace damaged components. Remove and clean out y-strainer element. See
sections 9.1(b) and 9.2(b)
8.4.
Closure Assembly: Before pressurizing the bulk abrasive blaster the camlock handle assemblies
(#29) and all other closure (#5) components must be closely inspected for defects as follows:
CLOSURE ASSEMBLY INSPECTION POINTS
a)
Inspect closure O-ring for shrinkage, swelling, cuts, or tears.
b) Inspect O-ring sealing surfaces for corrosion, cracks, deformations, paint, or other trash.
c) Inspect for presence of swing bolt nuts and washers.
d) Inspect swing bolts for corrosion, wear, cracks, deformations, paint, or other trash.
e) Inspect (2) nuts for corrosion, wear, cracks, or deformations.
f) Inspect threads on swing bolts and nuts for corrosion or wear.
g) Inspect cams for presence of spring pins.
h) Inspect closure hinges for ease of operation.
i) Inspect camlock handle assemblies for ease of operation.
j) Periodically lubricate swing bolts with a hydrocarbon-base lubricant.
Clean debris off all components. Replace all missing and defective components. Any camlock,
swing bolt, nut, or hinge that show signs of damage, corrosion, wear, or does not swing freely
must be repaired or replaced prior to re-pressurizing the blast vessel. The camlock handles must
be installed into the cam lugs as shown in Figure 8.1(b) so there is no interference with closure
head handle or hinges, and to insure proper operation of the closure Halok (#6). The torque on
the camlock assembly nuts must be properly adjusted. See Section 8.5 for camlock adjustment.
The closure assembly is part of a Pressurized Vessel. Propelled objects will cause serious injury
or death. Depressurize vessel before opening the closure assembly. See Section 6.2.
