About this showcase:The four images on this page are AI-generated illustrations of product forms, intended to explain pipe and fitting categories. They are not photographs of installed projects. Actual appearance, materials, dimensions, joint construction and permitted applications are subject to the confirmed model documentation and physical products.
Gudian Technology conducts business in thin-wall stainless steel water pipes and press-fit fittings from Kunming, Yunnan. To enquire about pipes, fittings or pipework for water treatment equipment, provide the intended use, specifications and site-interface information first. Supply scope, quantities, lead times, installation and site services are confirmed for each project.
How to use the category showcase
Identify the pipe or fitting category required for the application, then check the size and connection method at each end. These are general categories, not confirmation that all models are available or in stock. Single-press, double-press and other connection systems must each be checked against the actual product documentation.
- Pipe forms:Thin-wall straight pipe, blue-coated pipe, red-coated pipe and crossover bends.
- Joining and end closures:Equal couplings, reducing couplings and end caps.
- Changes of direction and branches:90° elbows, 45° elbows, equal tees, reducing tees, equal crosses, type B 90° elbows and 90° reducing elbows.
- Straight adapters:Female-threaded adapters, male-threaded adapters, union adapters and flange adapters.
- Elbow adapters:90° female-threaded elbows, 90° male-threaded elbows, short female-threaded elbows and swivel-nut elbows.
- Tee adapters:Female-threaded tees and male-threaded tees.
These names help organize an inquiry list. Matching names, images or nominal sizes do not establish steel grade, pressure rating, suitability for food contact or compatibility between brands. Provide documentation for the relevant models.
Pipe showcase: bare pipes, coated pipes and crossover bends
The showcase includes common forms of thin-wall stainless steel straight pipe, red- and blue-coated pipe, and crossover bends. The choice between bare and coated pipe depends on the installation environment and design requirements. Image colors do not establish steel grade, temperature rating or intended use. Crossover bends illustrate an option at intersecting pipe routes; check product drawings for the actual dimensions and connection method.
Basic press-fit fittings: joints, changes of direction and branches
Couplings, reducing couplings, elbows, tees, crosses and end caps are common fitting names used to discuss pipe connections and layout. First define the size at each connection, the required direction and any branches, then check the matching pipe-and-fitting system. A similar appearance or the same nominal size does not establish interchangeability.
Adapters: threaded, union and flange connections
For connections to equipment, valves or other interfaces, check whether a female thread, male thread, union or flange adapter is required. State the type and size of each end in the inquiry. Confirm thread standards, flange specifications, sealing method and disassembly requirements together; do not select fittings from a photograph alone.
Connecting to water-supply and water treatment equipment
Discuss piping requirements for equipment inlets and outlets, distribution after storage, and points of use together. The suitability of thin-wall stainless steel pipe depends on the conveyed fluid, temperature, pressure, environment and design requirements. For purified water, cleaning or disinfection, check material and seal compatibility separately. Pipework does not replace water treatment, and a material name is not evidence that the resulting water meets a required standard.
Prepare this information before requesting a quotation
- Application and location:The water or fluid to be conveyed, project location, indoor or outdoor installation, and equipment to be connected.
- Specifications and quantities:Pipe diameter, wall thickness, length and fitting list; include any existing design or selection schedule. Requirements for grades such as 304 or 316L should have a clear basis in model specifications or documentation.
- Interface information:Port sizes, thread or flange types, and the brand and series of existing pipes and fittings. If model details are unavailable, provide photographs of nameplates and connections rather than judging compatibility by appearance alone.
- Operating conditions:Design temperature, pressure and environment. Check seal materials, tools and press-jaw compatibility with the connection system against the manufacturer's documentation.
- Service scope:Whether you require pipe and fitting supply, compatibility advice or site services, together with timing and handover requirements. The final confirmed scope applies.
Frequently asked questions
Can press-fit fittings be used directly with pipes from another brand?
Do not confirm mixed-brand use from nominal size or appearance alone. Check pipe dimensional tolerances, fitting construction, seals and tool requirements, and obtain the relevant product documentation or explicit confirmation from the supplier.
Can an image establish whether a pipe is 304 or 316L stainless steel, or show its wall thickness?
No. Images on this page illustrate categories. Check materials, wall thickness and performance against the specific model, product documentation and physical items. Add test or acceptance documentation where the project requires it.
Can I enquire about pipes and water treatment equipment together?
Yes. Start by discussing the intended uses and interface requirements for both equipment and pipework. Supply, construction and site services are confirmed separately; they are not automatically assigned to the same provider for every project.
What governs installation and acceptance?
Follow the applicable design documents, product installation instructions and relevant standards, with work organized by personnel with the appropriate competence. Define installation, pressure testing, flushing and handover requirements for the project. The illustrations on this page are not construction or acceptance instructions.
Pipe and fitting inquiries across Yunnan's 16 cities and prefectures
For thin-wall stainless steel water pipes and press-fit fittings in Kunming or elsewhere in Yunnan, start remotely with the application, specifications, quantities and equipment interfaces. In the service-area resource directory, select the actual project location. An administrative area does not indicate a local branch, available stock or a completed project. Supply, transport, installation and site visits are confirmed for each project.
