Review pipes, fittings and seals as a compatible assembly. Photographs help identify shapes and prepare a list, but cannot establish material grade, wall thickness, pressure rating or hygienic performance. These require documents for the actual model.
Three parts with different revision years
The official search checked on 9 October 2026 lists GB/T 19228.1—2024 for press-fit fittings, GB/T 19228.2—2011 for connecting thin-wall stainless steel pipe, and GB/T 19228.3—2012 for rubber O-ring seals as current. The 2011 edition of Part 1 is withdrawn. Do not label every part of the series as a 2024 edition.
Display information and quotation checks
| Displayed item | Check before quotation | Evidence to retain |
|---|---|---|
| Bare and coated pipe | Actual outside diameter or size, wall thickness, length and use | Model data, material and supply documents |
| Elbows, tees and couplings | Connection dimensions, construction and pipe compatibility | Part numbers and dimensional information |
| Threaded and flanged adaptors | Connection system, equipment interface and installation clearance | Details of both ends, rather than a product name alone |
| Seals and pressing tools | Material conditions and compatibility of the tool and jaws with the assembly | Component requirements and tool instructions |
| Delivery and installation | Batch, item list and agreed installation and inspection requirements | Traceable supply and handover records |
Using existing photographs
Use shape names that can be confirmed and mark unknown fields as requiring model-specific documents. A supplier’s standards table is not proof that a product on this website conforms. A past supplier relationship is not a current brand authorization. Check each model before purchasing; installation and testing depend on the actual project and applicable requirements.
Frequently asked questions
Can all press-fit fittings be used with any thin-wall pipe? Check component dimensions, construction, seals and tools. Similar appearance does not establish compatibility.
Can the display promise no rust or lifetime maintenance-free use? An unconditional promise without evidence is inappropriate. Actual documents should define environmental suitability and maintenance.
References and scope
References checked on 9 October 2026. These are public reference materials. Gudian prepared the information checklists for project enquiries. A supplier manual does not establish a brand authorization for this website, and a paper does not show that Gudian equipment has achieved its research results.
- China’s official standards database: GB/T 19228 series; Part 1—2024, Part 2—2011 and Part 3—2012 listed as current when checked on 9 October 2026. Review fittings, pipe and seals separately; this is not proof of product conformity.

Equipment and consumable requirements can first be discussed remotely. Supply, installation and site visits are confirmed for each project. Send only the equipment and water-quality information needed for the enquiry, and conceal personal contact details and sensitive third-party information in photographs.
