IN PRESSURE CONTAINMENT, the inspector shall verify that the installation of new materials is consistent with the selected or specified construction materials. This material verification program should be consistent with API RP 578. Using risk assessment procedures, the owner/user can make this assessment by 100-percent UL Standard verification, PMI testing in certain critical situations, or by sampling a percent- age of the materials. PMI testing can be accomplished by the inspector or the examiner with the use of suitable methods as described in API RP 578. If a piping system component should fail because an incor- rect material was inadvertently substituted for the proper pip- ing material, the inspector shall consider the need for further verification of existing piping materials.

The extent of further verification will depend upon circumstances such as the con- sequences of failure and the likelihood of further material errors. The owner/user shall assess the need and extent regarding application of the practices consistent with API RP 578 addressing inadvertent material substitution in existing alloy Control valves or asme bpvc section viii div 1 other throttling valves, particularly in high-pressure drop-and-slurry services, can be susceptible to localized corrosion/erosion of the body downstream of the orifice. If such metal loss is suspected, the valve should be removed from the line for internal inspection. The inside of the downstream mating flange and piping also should be inspected for local metal loss.

When valve body and/or closure pressure tests are per- formed after servicing, they should be conducted in accor- dance with API Std 598. Critical check valves should be visually and internally inspected to ensure that they will stop flow reversals. An example of a critical check valve may be the check valve located on the outlet of a multistage, high head hydroprocess- ing charge pump. Failure of such a check valve to operate correctly could result in overpressuring the piping during bing.com a flow reversal. The normal visual inspection method should include: a. Checking to insure that the flapper is free to move, as required, without excessive looseness f

4.2.2.5 Pump type OH5 Close-coupled, vertical, in-line, single-stage overhung pumps shall be designated pump type OH5. Close-coupled pumps have their impellers mounted directly on the driver shaft.

t 0.010 in. Cylinder Running Clearance C.9 Vertical Runout Adjustment C.9.1 If it is believed that some adjustment is necessary to the vertical runout readings, it must first be assured that cylinder alignment and cylinder level are properly set so that the components are free of harmful stresses at operating conditions. If crosshead shim adjustment is then considered necessary by interchanging shims under the crosshead shoes, it should be remembered that taking shims from the bottom shoe and placing them under the top nature.com shoe drops the crosshead centerline further below the perfect alignment centerline. This decreases the DROP and thus decreases the positive rod runout at the crosshead, but may actually increase negative runout at the packing case due to sag. This is illustrated on Figure C-5C and in the series of five runout curves of Figures C-6 through C-10. With reference to Figures C-6 and C-9, note that a 0.76 mm (0.030 in.) change of shims, that would put the crosshead and piston on the same centerline such that DROP = 0.00, changes the runout by only 0.076 mm (0.003 in.), that is, the crosshead runout goes to +0.079 mm (+0.0031 in.) from +0.155 mm (+0.0061 in.), and the runout at the packing case goes to -0.056 mm (-0.0022 in.) from +0.020 mm (+0.0008 in.). In other words, for this example, rod runout is changed by only 0.0254 mm (0.001 in.) for each 0.254 mm (0.010 in.) of shims removed from the bottom shoe in an attempt to lower the crosshead closer to the centerline of the cylinder. Because rod length and rod diameter, which affect sag, and cylinder size, which affects running clearance, can significantly affect vertical runout, every compressor cylinder assembly must be fully evaluated for expected vertical runout based on perfect alignment conditions. If crosshead shims are shifted in an attempt to adjust vertical runout, it is important that the crosshead always be installed api download with the "top" side up following removal for maintenance.
