LPG & CRYOGENIC EXPORT PROCUREMENT
Ethylene & Ethane Cryogenic Storage Projects
Submit separate ethylene and ethane medium/duty datasheets and organize tanks, pumps, cryogenic piping, boil-off or recovery and controls around the chosen storage construction. Start with one item or a full project list. Define process performance, hazardous areas, structural/protective design, local site responsibilities and actual manufacturing origins; similar names are not a common selection basis.
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
Ethylene & Ethane Cryogenic Storage Projects
| Purchase item | Conditions to provide | Supply and responsibility boundary |
|---|---|---|
| Ethylene | Composition/impurities, storage temperature/pressure, turnover and downstream process | Ethylene-specific design basis and datasheet |
| Ethane | Independent composition, feed state, inventory and outlet duty | Ethylene/LNG conditions are not an approved ethane basis |
| Project scope | Pressurized or atmospheric storage, boil-off, pumps and insulated piping | Separate specialist supply, joint manufacture and site construction |
Conceptual equipment sequence
Purchasing sequence only, not a P&ID or construction drawing. Confirm process, safety and control design for the actual site.
- 1Separate ethylene/ethane bases
- 2Storage and equipment selection
- 3Fabrication/sourcing/site interfaces
- 4Agreed tests and handover
Send the information already available
- Each medium specification, equipment list, process drawings and design conditions
- Site, ambient, utilities, controls and recovery interfaces
- Destination inspection, sectional transport, construction and delivery arrangements
- 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.

Liquid Ethylene Storage & Supporting Equipment
Prepare an ethylene-storage RFQ from composition, storage state and process interfaces.
Liquid Ethane Storage & Equipment Procurement
Assess ethane storage against its own medium datasheet rather than copying ethylene or LNG storage conditions.
Large Atmospheric Cryogenic Flat-Bottom Tanks
Large atmospheric cryogenic flat-bottom tanks have a different procurement and construction scope from pressurized cryogenic vessels.
Cryogenic Pumps & Transfer Equipment
Submit medium state, inlet conditions, flow/head, continuous or intermittent duty and downstream pressure together for a cryogenic pump RFQ.

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.

PROJECT INQUIRY
One item, an equipment combination or a project package
Start with the files and conditions you have. Sales can clarify missing items; destination approvals, performance, lead time and site services need a project-specific agreement.
