STATUS: In Service

1. The Vessel V-636 was inspected by TesTex, Inc. for an API-510 external evaluation. All thickness readings

collected for this inspection exhibited little to no corrosion from previous inspection. No mandatory repairs

were noted during this inspection. Several non-mandatory items were noted. Attached pressure gauge dial

lenses were noted to be cracked, but can still be read. Some cracking in the containment dike wall over the

containment drain is present. The dike drain is partially clogged with debris and dirt. The top concrete blocks

of the dike are missing cement and are crumbling. The vessel is not grounded. Pressure relief piping exhibits

surface corrosion, and should be cleaned and painted.

2. Ultra Sonic thickness readings and visual inspection were the primary non destructive methods used to

inspect the vessel.

3. Industry standards used to inspect and evaluate the vessel were

API-510 (pressure vessel inspection code)

ASME Sec. VIII Div. 1.(rules for construction of pressure vessels)

DATE: July 9, 2019SERVICE:

Recommendations:

Condition 2 Condition 3

Damage and/or failure noted. Requires

repair and/or re-inspection prior to

returning to service.

Minor damage noted with low

likelyhood of failure/risk. Repair

per industry best paractice.

Condition 1

Major damage/failure or safety related

item noted; requires immediate

attention. Vessel not fit for service.

Action to be taken

The vessel is not grounded. Grounding is not

required by ASME BPVC Sec. VIII but is

recommended by RP API-571.

Attach a grounding strap of no more than

25 Ohms electrical resistance.

Action Items:

Description

The walkway platform shows mild surface

corrosion.

The discharge piping should be cleaned

and painted.

Consider cleaning and painting the

walkway platform.

Considere replacing the cracked dial

glasses.

A crack is located in the concrete

containment dike wall above the dike drain.

Considere repairing the crack in the dike

wall.

The containment dike drain is partially

clogged with dirt and debris

Considere cleaning the dike drain.

Pressure relief discharge piping shows signs

of paint failure and surface corrosion.

Dial glasses of both mechanical pressure

gauges are cracked, but still can be read.

External Inspected Condition by Component:

Welds

East Head

West Head

The West head shows no signs of buckling, cravking, or previous

leaking. Previous external pitting is visible beneath the external

coating.

The East head shows no signs of buckling, cravking, or previous

leaking. Previous external pitting is visible beneath the external

coating.

Welds, examined through the vessel external coating, are in good

condition.

Support Structures

The vessel is supported by four v-shaped legs on top of 2 concrete

pedestals. The legs are attached by painted anchorbolts.

ConditionItem


Grounding

Pressure Releif Devices

The vessel is not grounded. Grounding is not required by the vessel's

construction code, but is recommended by RP API-571.

V-636 is protected from over-pressurization by 2 PSVs set at 250 psi

and 2 rupture discs set at 250 psi.

Associated Piping

Attachments

Instruments

Nozzles

Attached electrical conduit support is in good condition.

PSV discharge piping paint has failed. The piping shows paint failure

and signs of surface corrosion.

All vessel nozzles were visually examined and found to be in good

conditon. UT thickness readings could not be taken due to the nozzles

threading.

Attached mechanical pressure gauges have cracks in the glass lenses

covering the dial. The gauges can still be read. The digital gauge is in

good condition. Piping associated with the digital pressure gauge

shows signs of surface corrosion.

Secondary Containment

The dike wall top concrete blocks are missing cementand are not

secured to the rest of the wall. A crack is above the dike drain. The

dike drain is partially clogged.

A U-1 and manufacture's drawing were available at the time of

inspection. Previous inspection reports were also available.
