LPG & CRYOGENIC EXPORT PROCUREMENT
Liquid Ethane Storage & Equipment Procurement
Assess ethane storage against its own medium datasheet rather than copying ethylene or LNG storage conditions. Submit a list covering the cryogenic tank, transfer pump, piping, valves and related equipment. Huawang organizes the proposal through the applicable fabrication, specialist sourcing and joint-supply roles; process design and local compliance responsibilities are assigned in the contract.
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
Liquid Ethane Storage & Equipment Procurement
| Purchase item | Conditions to provide | Supply and responsibility boundary |
|---|---|---|
| Material stream | Ethane composition, impurities, inlet state, inventory and turnover | Confirm an independent design basis; similar media are not substitutes |
| Storage construction | Operating/design temperature/pressure, tank type, insulation and site constraints | Match the actual manufacturer and inspection plan to the construction |
| Transfer equipment | Pump inlet conditions, flow/head, recycle, valves and instrumentation | Confirm specialist equipment origin and system interface list |
Conceptual equipment sequence
Purchasing sequence only, not a P&ID or construction drawing. Confirm process, safety and control design for the actual site.
- 1Ethane feed
- 2Service-specific storage
- 3Transfer and circulation
- 4Process interface
Send the information already available
- Medium specification, inventory/quantity and operating/design conditions
- Transfer/utilities and boil-off or recovery interfaces/boundaries
- Destination requirements, documents, packing and transport envelope
- 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.
