Argonne National Laboratory Statement of Work Design, fabrication, and delivery, of ASME U-stamp certified pressure vessels for Single-Cylinder Hydrogen Internal Combustion Engine (ICE) November 14, 2024

1.0 Background

This project requires a supplier to construct, as per ASME BPVC Sec. XIII, and deliver two ASME U-stamp certified pressure vessels. The pressure vessels are to be used as surge tanks for intake and exhaust gas flows for a Single-Cylinder Internal Combustion Engine (ICE) operated with either diesel or hydrogen fuel for applied research programs at Argonne National Laboratory (ANL). Additional context for the intended application may be found in the supplementary document, “Supplementary - Surge Tanks for Single Cylinder Engine.docx”. As such, Pressure Vessel #1 will be referred to as the “Intake Surge Tank” and Pressure Vessel #2 will be referred to as the “Exhaust Surge Tank.” Each vessel has slightly different design requirements which are described in this document. The supplier will be expected to undertake the required engineering activities to design suitable pressure vessels and to provide technical drawings to ANL for approval prior to constructing the pressure vessels. The supplier shall then fabricate, certify, and deliver the pressure vessels within the mutually agreed upon time frame. The finished pressure vessels are to be delivered to Argonne National Laboratory (ANL), Bldg. 46, Lemont, IL.

2.0 Scope

Under the present contract, ANL expects to obtain two ASME-certified pressure vessels required for intake and exhaust surge tanks for Single-Cylinder ICE experiments, auxiliary hardware, technical drawings, and certification documents.

3.0 Objectives

3.1 Work Task 1 Design pressure vessels

· Supplier shall design two pressure vessels meeting the requirements and design specifications for each surge tank.

· Supplier shall provide technical drawings of each tank including overall dimensions, size and location of threaded ports and flanges, and configuration of attached mounting brackets.

· The ANL Technical Team shall be granted 10 business days to review and request modifications prior to design approval and fabrication of pressure vessels.

3.2 Work Task 2 Construct - as per ASME BPVC Sec. XIII - and emboss certification stamp on nameplate

· Supplier shall procure all relevant parts and raw materials (e.g., tubes, plugs, flanges etc.) to construct pressure vessels designed in Work Task 1 (Sec 3.1).

· Supplier shall procure additional flanges needed to mate tubing (at ANL) to the pressure vessels (two for each vessel) to be shipped with the completed pressure vessels.

· Supplier shall fabricate the two pressure vessels according to the approved design from Work Task 1 (Sec. 3.1) and in accordance with ASME U-Stamp standards.

· Supplier must conduct a pressure test to certify the pressure vessels for a maximum allowable working pressure (MAWP, also see “Design Pressure” in Table 4.1) of 6 barg (for the intake surge tank) and 4.5 barg (for the exhaust surge tank). The pressure test shall be performed in accordance with ASME standards.

· Supplier must conduct a Hydro (as preferred option/ alternatively pneumatic) leak test at the design pressure, certifying it as leak free.

· ANL will source and purchase ASME UV-certified pressure relief valves to be installed on the pressure vessels as described in Sec. 4.2.

· The supplier shall emboss ASME U-stamp certification on nameplate on pressure vessels meeting the ASME standard.

· After the supplier has completed the fabrication of the pressure vessels, supplier shall send notification to ANL technical representative. The ANL technical representative may visit the supplier facility for visual inspection of the tanks prior to shipment.

· The supplier will ensure that the pressure vessels are dry and free of oil before shipping.

4.0 Tasks

4.1 Work Task 1 Design pressure vessel

· Supplier shall provide technical drawings which will constitute the official fabrication documents.

· ANL will provide written approval of the technical drawings.

4.2 Work Task 2 Construct - as per ASME BPVC Sec. XIII - and emboss certification stamp on nameplate

· Construct two pressure vessels adhering to the general specifications listed below, along with each pressure vessel’s particular specifications. Note that the configuration of the two pressure vessel ports are mirror images of each other.

Table 4.1: General Specifications for both pressure vessels

· The Intake Surge Tank (Pressure Vessel #1) will have the following particular specifications in addition to the general specifications and will be configured according to the concept drawing in Figure 4.1.

Table 4.2: Particular specifications for Intake Surge Tank (Pressure Vessel #1)

Figure 4.1: Concept drawing for Intake Surge Tank

· The Exhaust Surge Tank (Pressure Vessel #2) will have the following particular specifications in addition to the general specifications and will be configured according to the concept drawing below.

Table 4.3: Particular specifications for Exhaust Surge Tank (Pressure Vessel #2)

Figure 4.2: Concept drawing for Exhaust Surge Tank. Note that its configuration is a mirror image of the Intake Surge Tank represented in Fig. 4.1.

5.0 Delivery

Delivery will consist of two pressure vessels, four mating flanges (two for each vessel); all inspection, certification, and test reports; engineering report including final technical drawings. Shipment shall be insured and be addressed to:

Argonne National Laboratory 9700 S Cass Ave, Bldg. 46 Lemont, IL 60439 USA

Note that package should be delivered to Bldg. 46 (Shipping and Receiving) and the intended work and assembly will take place in Bldg. 371 Highbay. Detailed procedures associated with delivery are noted below:

5.1 Delivery and Inspection Procedures

· Supplier will package and ship (via insured carrier to Argonne National Laboratory, Bldg. 46, Lemont, IL.) the completed pressure vessels, ASME certification documentation, and final as-built technical drawings to ANL for inspection and functional testing.

· Pressure vessels will be visually inspected by ANL for adherence to the agreed upon technical drawing. If the parts received are out of specifications, the supplier will provide necessary modifications/ repairs at no additional cost to ANL.

· Pressure vessels will be visually inspected by ANL for damage during shipment. If pressure vessels are dented, gouged or otherwise damaged upon arrival, they must be replaced/ repaired by the supplier at no additional cost to ANL.

· Pressure vessels will be visually inspected by ANL to confirm the presence of required ASME U-stamp and appropriate accompanying certification documents, including ASME U-1A Manufacturer’s Data Report form.

· ANL will perform a pneumatic leak test at ½ the design pressure of the pressure vessels with the safety valves installed. If leaks are detected from the pressure vessel, the supplier will make the necessary modifications/ repairs at no additional cost to ANL.

· Post ANL inspections and leak test, in the case of failed pressure vessel, ANL may return the pressure vessel back to the supplier for evaluation and modification to improve performance of the pressure vessel.

· The contract will be concluded when the pressure vessels pass the inspections and leak testing at ANL. Inspection and leak testing of the pressure vessels must be conducted within 20 business days of the delivery of pressure vessels.

5.2 Acceptance Criteria – Delivery must fulfill the following requirements to be accepted by ANL

· ANL is provided the allotted time to review, request modifications, and approve technical drawings of the proposed tank design before fabrication takes place

· The tanks are fabricated according to the approved technical drawing from Work Task 1 and be representative of concept drawings in this document.

· Pressure vessels must be constructed to ASME U-stamp certification standards and be delivered with all certification paperwork. Nameplate on each vessel must have a U-stamp with all required fields filled out, e.g., MAWP rating at design Temperature, name of manufacturer, serial number, date manufactured.

· Pressure vessels must be passivated by nitric acid pickling on all surfaces, clean, dry, and free of visible damage (gouges, dents, etc) upon arrival to ANL.

· Delivery to ANL includes two pressure vessels, four corresponding mating flanges, NPT plugs in all tapped holes, and flange caps required for onsite pressure testing of both vessels.

· Pressure vessels must pass inspections/leak testing performed by ANL as described in Section 2, Work Task 3.

· The following documentation must be delivered to ANL: Final as-built drawings, ASME U-1A Manufacturer’s Data Report form, inspections and test reports, and associated documentation as described in attached form ANL-407C.
