The abrasive blaster 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 daily 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, and holes. See Figure 8.1.
8.4. Air leaks at the abrasive inlet will cause the air pressure in the blast vessel to drop. Pressure
drop in the blast vessel can cause abrasive flow problems. Prior to initial use and periodically
thereafter, the popup and popup gasket should be checked. Inspect the popup as follows:
a) Depressurize the Mini abrasive blaster per Section 6.2.
b) Disconnect air supply hose from the crowfoot (#2).
c) Inspect the popup gasket (#6) and popup head (#5) sealing surfaces for wear or
deformations. Replace either if necessary.
d) Check the gasket alignment in the retaining ring. Proper gasket fit is necessary for the
popup to seal the opening.
e) Pull the popup against the gasket and check for proper seating as shown in Figure 8.1.
f) After checking the alignment and gap, the blast vessel can be re-pressurized and the
popup is then checked for leaks. If a leak is present, repeat the above steps to isolate the
problem.
g) If the popup must be replaced it can be removed from the blast vessel through the
abrasive outlet at the bottom of the vessel. Remove the Thompson Valve ® II (#10) and
the outlet bushing (#39). See Figure 7.3.
Pinch point hazard. Vessel pressurization will close the popup. Keep hands and fingers away
from popup. Disconnect air supply prior to performing popup maintenance.
