6.4 Closure Assembly Closing Procedure (See Figure 6.4.1 and 6.4.2)
6.4.1. Inspect the closure head and sealing surface for damage including, but not limited to,
corrosion, cracks, or deformations. Check that the 10” O-ring is fitted in the groove at
the bottom of the closure head. Remove and inspect the
closure O-ring for cuts or tears.
Replace if necessary. Replace the O-ring and adjust to remove kinks or twists.
6.4.2. Close the closure head and check for alignment with closure hub. If the closure head
does not close properly, do not attempt to pressurize the bulk abrasive blaster. Take the
bulk abrasive blaster out of service and have it inspected and/or repaired by a qualified
facility. Contact Axxiom Manufacturing, Inc. for technical support.
Do Not operate the bulk abrasive blaster with a closure head that does not close
properly. Component failure will result. Component failure will cause serious injury or
death.
6.4.3. Each time the closure assembly is opened all the camlock assemblies and hinge
assemblies must be inspected for damage, including but not limited to, corrosion,
cracks, and deformations. Make sure all the swing bolts, nuts, washers, cams, spring
pins, and handles are in place (See Drawing 9.3(a)). Inspect the threads of each swing
bolt and (2) nuts for corrosion or wear. Each camlock assembly and hinge must be
tested for ease of operation. Any camlock, swing bolt, nut, or hinge that show signs of
damage, corrosion, wear, or does not swing freely must be repaired or replaced
before
re-pressurizing the blast vessel. The camlock handles must be installed into the cam lugs
as shown in Figure 6.4.1(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 Sections 8.4 and 8.5 for closure
assembly maintenance instructions and adjustment procedures.
The closure assembly is part of a Pressurized Vessel. Component failure will propel
objects causing serious injury or death.
DO NOT operate the bulk abrasive blaster with a closure assembly that has damaged or
worn components. Use of the closure assembly with worn or damaged parts will result
in component failure.
6.4.4. Swing all the swing bolts into position within the holding lug. Be sure each swing bolt
has the required (2) nuts and flat washer, and they are in good condition. See Figure
6.4.1.
Do not use a hammer, wrench, or any such tool or device to strike the camlock handles
(#29) or swing bolts into position. Use of such tools or devices can cause damage to
parts resulting in component failure. Component failure will cause serious injury or
death.
6.4.5. After all the swing bolts are in position within the holding lugs rotate the Halok® (#6)
clockwise to allow access to the camlock handles (#29). See Figure 6.4.1.
