VA Prescott Healthcare System needs the following. This Statement of Work (SOW) describes the requirements for boiler and feedwater deaerator inspections, the inspection, testing and calibration of the boiler plant burners, controls, and instruments by qualified technicians. Boiler Plant inspections, safety device testing and calibrations are required to maintain compliance in accordance with (IAW) VHA Directive 1810, NFPA 85, and ASME Boiler & Pressure Vessel Code. 2.2. Background. The services described in this SOW are required to maintain compliance with the VHA Directive 1810 Boiler and Boiler Plant Operations, NFPA 85 Boiler and Combustion Systems Hazards Code, and ASME Boiler and Pressure Vessel Code. Department of Veterans Affairs Medical Centers (VAMC) have a central high-pressure boiler plant to provide steam for heating and air conditioning, domestic hot water, kitchens, and sterilization. Boiler plant safety, reliability, efficiency, and equipment longevity are paramount concerns of NAVAHCS management. Boilers and feedwater deaerators are pressurized devices containing steam and hot water. They can fail catastrophically causing injuries and death and massive property damage. Regular inspections by experts are an essential part of a program to address these concerns. 2.3. Scope. Contractor will be required to provide the following services for the maintenance, inspections, analysis, and testing of electrical normal and emergency power equipment and systems. A list of equipment that will be tested will be attached separately Inspection Requirements: Annual internal and external inspections are required for each boiler. Internal inspections of the feedwater deaerator pressure vessel are required every six years (or more frequently if welding repairs have been performed). At least two weeks notice to NAVAHCS is required prior to an inspection. Also, the inspection must be scheduled for periods when NAVAHCS determines that the boilers that will be inspected internally will not be needed for steam supply and when the Contracting Officer s Representative (COR) or his/her designate is available on site to monitor the inspections. To maintain steam service, typically only one boiler at a time will be scheduled for internal inspections per inspection visit. Thus, multiple visits per VAMC facility will be necessary every year to inspect all the boilers internally. Feedwater deaerator pressure vessel inspections must be scheduled during periods of low steam demand. Coordinate the inspection schedule with the COR so that NAVAHCS can prepare the boilers and feedwater deaerator for the inspections in advance and have personnel available to monitor the inspections. Boilers scheduled for internal inspection will be prepared for the inspection by NAVAHCS prior to the scheduled arrival of the inspector. This includes cooling the boilers to near ambient temperature and having all manways, handholes and furnace access doors open; the boilers cleaned of loose materials waterside and fireside; electrical lock-out, tag-out in place; connecting piping isolated; proper illumination provided; compliance with confined space access requirements including having safety personnel present in the boiler plant. Similar advance preparations will be made to the feedwater deaerator when it is scheduled for internal inspection. NAVAHCS will comply with any other requirements of the inspector that are considered reasonable by NAVAHCS and have been presented in writing at least two weeks prior to the scheduled inspection. The boiler and feedwater deaerator inspections shall comply with the guidelines in the current issue of the NATIONAL BOARD INSPECTION CODE, Part RB, Inservice Inspection of Pressure- Retaining Items, and ASME Boiler and Pressure Vessel Code, Section VI or VII as applicable. In addition to those guidelines, the inspections shall comply with all NAVAHCS requirements as listed in this document. The inspector must completely enter the internal spaces of the boiler or feedwater deaerator and visually inspect all internal surfaces that can be accessed. Methods for testing safety devices shall comply with VHA Boiler Plant Safety Device Testing Manual, 4th Edition. Summary of the minimum inspection requirements for boilers: Review the boiler history including: operating conditions, date of last inspection, current inspection certificate, ASME stamping on boiler, National Board registration number, history of repairs and modifications. Review boiler logs, water test reports, and reports on tests performed on the burner controls and interlocks. Assess the external parts of the boilers and boiler accessories and piping and valves for safety, accessibility, proper maintenance and operation, cleanliness, and compliance with codes. Inspect for evidence of leakage of combustion gases or fluids, externally and internally, including all gaskets. Inspect foundations for signs of stress such as cracking or movement. Inspect boilers externally and internally for defects including bulges, blisters, cracks, wasted or eroded material, warping, general corrosion, grooving and pitting, damaged insulation. Inspect all accessible internal surfaces for waterside and fireside deposits, including scaling, sediment, debris, carbon deposits. Examine all stays and stayed plates. Inspect gas side baffles. Inspect internal drum surfaces and steam separating internals. Inspect soot blowers and verify proper alignment. Inspect tubes, tube ends and tube alignment. Check for sagging tubes. Verify that all nozzles of internal piping such as feedwater admission and bottom blowoff collection are clear with no obstructions. Inspect seating surfaces of manways and handholes. Check that boiler structure is plumb and level with no excessive deformations. Check for missing items such as bolts and nuts. Examine all valve and pipe connections to the pressure vessel. Inspect refractory including burner throat, expansion joint, bull ring, furnace seals, furnace walls and floor. Verify proper alignment of boiler assembly. Inspect furnace for evidence of flame impingement. Perform mechanical and electrical inspection of disassembled low water cutouts (disassembly by VA). Inspect piping connected to the boilers for evidence of leakage, provision for expansion, provision of adequate support, proper alignment, evidence of detrimental conditions. Inspect piping to the water column, low water cutoffs and alarms, gage glass. Verify that interior of piping is clear of obstructions. Provide recommendations for non-destructive testing when the inspections indicate that this is necessary to assure continued safety and reliability under current operating conditions. Summary of the minimum inspection requirements for feedwater deaerators: Review the feedwater deaerator history including: operating conditions, date of last inspection, current inspection certificate, ASME stamping, National Board registration number, materials of construction, extent of postweld heat treatment, history of repairs and modifications. Assess the external parts of the feedwater deaerator and accessories and piping for safety, accessibility, cleanliness. proper operation, and compliance with codes. Inspect for evidence of leakage. Verify that non-condensable gas vent line is open and proper orifice is provided to permit venting of gases. Inspect support structures for proper integrity and allowance for thermal expansion. Internal inspections (6-year intervals unless otherwise recommended because of welding repairs): Visually inspect all visible pressure vessel surfaces for corrosion, material thinning, deposits, and weld cracking. Inspect spray nozzles and trays. Certified American Society for Non-Destructive Testing (ASNT) Level II technicians shall perform non-destructive tests using the wet fluorescent magnetic particle (WFMT), ultrasonic testing (UT), and any other necessary non-destructive tests. Completely examine all accessible welds utilizing the WFMT test method. Properly prepare the surfaces before testing. Determine pressure vessel material thickness by UT. Thickness measurement locations shall be selected by dividing the storage tank heads into quadrants and taking measurements at each quadrant on two imaginary rings in each head (eight measurements total) . Measurement locations on the shell shall be on each of the quadrants, on four to six locations along the length of the shell (16 to 24 measurements total). The technician may recommend fewer or more tests to the owner, providing justification. Typically, the pressure vessel section containing the deaerator trays and sprays is not accessible for non-destructive testing. The experience is that this section, which is mainly exposed to steam, is less vulnerable to weld failures and material thinning than the storage section which contains condensate and make-up water. Calculate maximum allowable working pressure rating of vessel based on thickness measurements. Calculate depletion rate of material thickness. Inspection, Testing and Calibration Requirements: Technicians shall provide all tools and labor necessary to perform inspection, tuning, testing, calibrating, and adjustments of burners and boiler and boiler plant controls as specified below. This shall be done every 12 months in accordance with a schedule provided by VAMC. VAMC may extend the schedule for burners in limited service. Instrumentation, monitoring and data management systems as listed below shall be calibrated every 12 months. Provide at least two-weeks notice to the Contracting Officer s Representative (COR) prior to performing the work. Work cannot be scheduled during heavy steam load periods. Only one boiler at a time can be out of service for the inspection, testing and calibration procedures. Work must be conducted when the COR or his/her designate is available on site to monitor the work. VAMC will have the boilers that are to be serviced prepared for the technicians upon their scheduled arrival. This includes having the boilers clean of soot and loose scale; fully warmed and at normal steam pressure; steam exhaust silencer system operable; all boiler, burner and fuel train pressure gages and thermometers calibrated; fuel meters in accurate operation (pressure/temperature correction factors provided, if applicable); boiler steam flow, stack temperature and flue gas oxygen instruments operating.
