Define this task first
Confirm documents and handover before supply across regions
Enter the actual delivery address, contact, equipment packaging, and receipt-check items. If transshipment or a separate export is involved, transportation, documents, and applicable requirements need separate checking. A regional name cannot establish business scope.
How should delivery checks, missing-part records, and handover responsibilities be agreed?
Specify the delivery address and subsequent use separately
Enter the actual equipment-use location, delivery address, and intended use, stating whether the locations are the same. Provide transshipment arrangements separately when needed. A regional name is not evidence of export business. Transportation, documents, and applicable requirements for a separate export need additional checks.
Include packaging and accompanying documents in the list
Compare names, models, and quantities of equipment, consumables, parts, and accompanying documents, and agree on packaging, labeling, and delivery checks. Photos record appearance and packaging, but cannot alone prove internal performance, compliance qualifications, or compatibility of every component in the complete unit.
How to retain evidence for missing parts and abnormalities
Record packaging damage, missing parts, model mismatches, and similar issues as agreed, retaining delivery time, checking records, and action records. Distinguish supply issues from site-installation issues. Returns, exchanges, replacement parts, and subsequent installation arrangements follow the specific contract and actual confirmations.
Update the list before changing site connections
When purchasing thin-wall stainless steel water pipes for Dehong, revise the provision list first if site equipment or valve connections change. Press-fit fitting inquiries for Dehong must also update reducer, tee-branch, and male or female threaded-adapter specifications. An old quote does not automatically cover new connections. Confirm expenses and lead time against the revised requirements.
Keep a separate resolution record for missing items and interface changes
Before supply, list whether equipment, consumables, connectors, accompanying documents and tools are included, then inspect delivery using the same identifiers. For missing items, record quantity, discovery time, replacement responsibility and agreed handling. For an interface change, attach the original and proposed specifications and the confirming person; do not substitute parts on appearance alone. List the documents and confirmations needed for transport, installation and commissioning separately, and do not label unconfirmed items as complete.
Cross-region supply to Dehong: link model lists to delivery checks
List equipment, consumables and piping separately, with models, quantities, units, packaging and delivery dates. Check membrane housings, connections and seals for RO membranes; check outside diameter, wall thickness, connection systems and transition interfaces for press-fit fittings. Retain supply and batch documents at delivery; visual similarity does not establish interchangeability.
Pipe and fitting integration information
Display of pipes, basic press-fit components, and threaded/flange adapters. Check specifications, connections, and supply responsibilities for the actual use.
Gudian Technology conducts the relevant business in Kunming, with remote discussions available for different regions. Supply, transportation, and site services are confirmed project by project. A general display does not indicate local stock, shops, or completed projects.
Information to bring to this discussion
The table below can serve as a checklist for this inquiry. Mark unavailable information "pending confirmation" and distinguish estimates from measured records. Do not upload identity documents, customer lists, or internal confidential materials.
| Discussion item | Information to prepare | Confirmation needed |
|---|---|---|
| Use and receipt | Actual location, delivery address, intended use, and transshipment arrangements | Whether separate transportation or document checks are needed |
| Accompanying list | Models, quantities, packaging, and technical information | Site compatibility and delivery-check items |
| Abnormal-condition handling | Records of missing parts, damage, or model differences | Handling responsibilities, action records, and handover results |
| Change checks | Old and new connection dimensions, revised list, change locations, and quantities | Final version and responsibilities for additional supply |
| Missing-item and change records | Itemized identifiers, missing quantities, and original and proposed interface specifications | Responsibility and handling for replacements, and who confirms and records changes |
Expand the general inquiry and delivery checklist
- 01Project location
- Prefecture or city, district or county, intake point, equipment installation location, and whether different locations are involved. Do not upload identity documents or customer lists for an initial inquiry.
- 02Water source and testing
- Tap water, well water, surface water, or other sources; record sampling points, dates, testing organizations, and the report's applicable scope. Do not infer water quality from a city name.
- 03Treated-water use
- Production, cleaning, cultivation, drip irrigation, or other uses; provide the corresponding process, crop, or actual usage requirements. Acceptance requirements may differ by use.
- 04Demand and schedule
- Daily demand, peak hourly demand, permitted operating time, and storage arrangements. Mark values for confirmation when measured data are unavailable. Estimates must not be recorded as equipment guarantees.
- 05Equipment and site
- Existing equipment models, consumable specifications, power supply, space, drainage, operating environment, and site-access conditions. Equipment photos should avoid capturing personal or confidential information.
- 06Budget and delivery
- Specify the budget, supply list, transportation, unloading, installation, commissioning, acceptance, and after-sales scope. Timing and expenses are governed by the confirmations for this project.
- 07Plateau site and water temperature
- Actual installation altitude, seasonal feed-water temperatures, pump inlet pressure or water level, suction piping and power; review the specific model. Altitude is not a water-quality test.
- 08Sampling points and operating baseline
- Sampling locations, dates, units, temperature compensation, and normal and abnormal records. Keep raw water, treated water, nutrient solution and return water separate.

Information sources and service boundaries
The area guides organize enquiry topics; they do not establish this project’s water quality, local outlets, clients or deliveries. Technical references and identified local-industry reports have separate stated uses. Industry context is not Gudian project evidence. Supply and site services require confirmation per project.
Regional name reference Yunnan Provincial Department of Civil Affairs · Administrative Divisions ↗(The listed statistical tables are as of 2025-09-30; directory review date 2026-10-06). Technical content is written by Gudian Technology. Specific models, testing, delivery, and after-sales service depend on this project's confirmed documentation.
