LPG & CRYOGENIC EXPORT PROCUREMENT
Gas Pressure Regulation & Metering Skids
Start a regulation/metering RFQ with the gas inlet range, required outlet pressure, average/peak flow and metering reference basis. Separate oxygen/nitrogen/argon supply from fuel gas downstream of LNG regasification. Oxygen cleaning, purity and fuel-gas odorization have different inputs. Identify the actual makers and integration responsibility for valves, instruments, controls and skid piping in the quotation.
Heze Huawang Pressure Vessel Co., Ltd. is a pressure-vessel and process-equipment manufacturer in Heze, Shandong, China. This procurement scope combines the accepted fabrication boundary with identified specialist supply, joint manufacturing and integration where required.
EXPORT PROCUREMENT
Gas Pressure Regulation & Metering Skids
| Purchase item | Conditions to provide | Supply and responsibility boundary |
|---|---|---|
| Pressure control | Inlet variation, outlet range, turndown, standby and failure requirements | System design establishes stages, protection and changeover logic |
| Metering | Composition, flow reference basis, metering purpose and remote signals | Agree evidence separately for process and custody-transfer metering |
| Service differences | Oxygen cleaning, nitrogen/argon quality and required LNG fuel-gas odorization | Odorization is not a default feature for every gas train |
Conceptual equipment sequence
Purchasing sequence only, not a P&ID or construction drawing. Confirm process, safety and control design for the actual site.
- 1Gas after vaporization
- 2Filtration/regulation and protection
- 3Metering and project-required odorization
- 4Gas-network interface
Send the information already available
- Medium, inlet/outlet conditions, flow and quantity
- P&ID, instrument list, signal protocol and utilities
- Country, site protection, electrical requirements and inspection records
- Include installation country/site, medium, capacity or flow with unit basis, operating/design pressure and temperature, quantity, destination requirements, optional equipment, requested date and transport constraints. Mark unknown items as open; send the existing specification, drawing or equipment list first.
Manufacturing, documents and delivery agreement
| Purchase item | Conditions to provide | Supply and responsibility boundary |
|---|---|---|
| Equipment origin | Identify tank fabrication within the accepted scope and each vaporizer, pump or valve train as in-house, specialist-sourced, jointly manufactured or integrated | The quotation identifies actual makers, applicable credentials and responsibilities; a requested destination approval is not an existing certification |
| Inspection and documents | Agree datasheets, interface drawings, ITP, material/welding/NDE records, tests, cleaning, insulation/vacuum checks and operating documents as applicable | State applicability, language, witness party, review points and final dossier index in the order |
| Packing and transport | Confirm final envelope, net/shipping weight, centre of gravity, lifting points, supports, preservation, packing and loose-item list | Agree port/road limits, shipping sections, handling equipment, delivery terms and transfer of risk for the project |
| Site work and local compliance | Overseas design, erection, piping, commissioning, inspection and turnkey requirements can be proposed and confirmed with qualified responsible parties for the actual scope | Equipment supply does not automatically include civil/fire/power works, permitting, medical-system validation or a complete station performance guarantee |
Evidence to check before order release
Confirm the proposed actual manufacturer, its current applicable credentials and scope, relevant equipment records, inspection plan and agreed sample dossier. Reference images show general manufacturing context only; specialist and joint supply retain the actual maker's identity.

RFQ WORKSHEET
Cryogenic tank and gas supply RFQ
Fill in known conditions only. Attach your existing drawing, equipment list or specification; we can help clarify the rest.Include refill intervals and gas-flow units / reference conditions to relate inventory to vaporization duty. Oxygen cleanliness, nitrogen / argon purity, LNG composition / boil-off and CO2 phase control are reviewed for the service. For ethylene, ethane, atmospheric tanks, medical LOX and accessories, specify the service state, destination and responsibility boundaries separately.
