Define this task first
Confirm processing, cleaning, and drinking uses separately
If a project includes processing, cleaning, drinking, or other stages, specify treated-water uses, required criteria, and applicable requirements for each one. Selecting process-water equipment does not mean drinking-water compliance has already been documented.
Are testing and acceptance requirements listed separately for different uses?
Why should processing and cleaning be recorded separately?
Specify contact subjects, usage stages, permitted conditions, and the source of criteria. Record whether cleaning, ingredient mixing, or other water uses occur simultaneously. Different uses may require different treatment targets and acceptance references. “For production” is not a complete requirements statement.
How should equipment selection be compared with usage requirements?
Provide the required criteria, actual demand, operating hours, and site conditions, and compare the tasks of different processes and specific model documents. General equipment descriptions cannot replace relevant business requirements. If drinking or another specific use is involved, check applicable requirements and corresponding evidence separately.
Operating documents provide evidence for the next adjustment
Retain inlet and outlet records, instrument and sampling information, consumable maintenance, and production changes. When changing the use or requirements, compare the original design conditions first, then discuss adjustments. Previously normal operation does not establish suitability for a new use.
Assess piping for different fluids separately
For thin-wall stainless steel water-pipe inquiries in Pu'er, first specify whether the conveyed fluid is domestic supply water, treated water, or a process-cleaning fluid. Selection of press-fit fittings in Pu'er must check material and sealing requirements for the intended use. A general water-pipe display cannot prove suitability for food contact, steam, or specialized processes.
Separate acceptance for product-contact and cleaning water
For production or cleaning projects, state whether water contacts the product and identify the actual requirements, demand and sampling points at each stage. Record results at treatment, storage and use points separately. For cleaning, list the chemical, rinse endpoint and equipment compatibility requirements separately. Drinking-water uses need relevant tests under applicable standards; low TDS or supply from the same system does not establish that all production and cleaning requirements are met. The user should confirm process suitability.
Processing projects in Pu’er: separate production, cleaning and drinking-water requirements
Clarify whether water enters the product, contacts equipment or is used for drinking, then ask the relevant process and hygiene personnel to confirm each requirement. “Processing water” does not specify a water-quality target by itself. Record sampling points, flow, cleaning-material compatibility and record-keeping responsibilities, and select equipment by duty.
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 |
|---|---|---|
| Usage stage | Processing, cleaning, or other uses and contact subjects | Required criteria and their basis |
| Equipment conditions | Model, demand, operating hours, and site | Process tasks and equipment scope |
| Change records | Old and new uses, operating records, and maintenance records | Whether additional testing and design checks are needed |
| Usage classification | Conveyed fluid, contact conditions, design requirements, and acceptance information | Product usage scope and corresponding evidence |
| Process stages and acceptance points | Product-contact statement, process targets, sampling points, and rinse and cleaning records | Who confirms process suitability, and how drinking-water and production requirements are separated |
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.
