In 2018, Nonleak supplied a coordinated stainless steel piping package for the Hongbao Jinxiu Riverside residential project in Ningxia, China.
The confirmed supply included 75,103 meters of 304 stainless steel pipe and 41,620 stainless steel Double Press fittings. The project provides an earlier real-world reference for Nonleak’s Double Press product family in a substantial residential development.

Residential Stainless Steel Piping Supply
The Hongbao Jinxiu Riverside project required a substantial quantity of stainless steel pipe and matching press-connected fittings for the confirmed project supply scope.
Nonleak supplied:
- 75,103 meters of 304 stainless steel pipe;
- 41,620 Double Press fittings;
- matching components for the specified stainless steel piping package.
The project demonstrates Nonleak’s ability to coordinate pipe and fitting manufacture for residential construction rather than supplying isolated individual fittings.
For the current product family, review Nonleak’s stainless steel Double Press fittings.
A 2018 Double Press Project Reference
One of the distinguishing features of the Hongbao Jinxiu Riverside project is its supply year.
The project was supplied in 2018, providing an earlier reference within Nonleak’s current portfolio of documented Double Press projects.
Project age alone should not be interpreted as a universal service-life guarantee. However, maintaining traceable records of earlier completed supplies can provide useful commercial evidence that the Double Press system has been used in real construction projects over multiple years.
304 Stainless Steel Pipe and Double Press Fittings
The confirmed supply used 304 stainless steel pipe together with matching Double Press fittings.
A Double Press connection is a system-level connection in which the stainless steel pipe, fitting socket, sealing element and compatible press tooling must work together correctly.
Project selection therefore needs to consider:
- pipe material and dimensions;
- fitting type and size;
- sealing-element specification;
- compatible press profile and tooling;
- operating medium and service conditions;
- inspection requirements;
- applicable project specifications and local approval requirements.
Nonleak’s broader product range is available through our stainless steel pipes section.
Project Supply Quantities
The Hongbao Jinxiu Riverside project involved a substantial quantity of both pipe and individual press fittings.
| Supplied Product | Confirmed Quantity |
|---|---|
| 304 Stainless Steel Pipe | 75,103 m |
| Stainless Steel Double Press Fittings | 41,620 pcs |
For project procurement at this scale, consistency across repeated production batches becomes important. Pipe dimensions, fitting geometry, material identification, surface condition and connection compatibility all need to remain controlled throughout the supply process.
Coordinated Pipe-and-Fitting Supply
Supplying the stainless steel pipe and matching Double Press fittings as part of one project package allows the procurement scope to be coordinated around a defined connection system.
This does not replace the responsibility of the project designer, contractor or approving engineer. Final material selection, system design, operating conditions, sealing requirements and installation procedures remain subject to the applicable project documents and local requirements.
For buyers, however, a coordinated pipe-and-fitting package can simplify the technical communication needed for product selection, quantity confirmation and supporting documentation.
Manufacturing and Quality-Control Support
Nonleak’s stainless steel piping production and inspection framework covers areas relevant to project supply, including material identification, dimensional inspection, product geometry, surface condition, traceability and connection-related quality controls according to the applicable product and project requirements.
Further information is available through our quality control and testing page.
Certificates, conformity documents and application approvals should always be checked against the exact product family, model, size, service medium and destination-market requirements rather than inferred from an unrelated project reference.
Domestic Project Experience and Regulatory Scope
The Hongbao Jinxiu Riverside project is a domestic China project reference involving Nonleak 304 stainless steel pipe and Double Press fittings.
The project partner or responsible party was Ningxia Hanas Gas Group Co., Ltd. The company name or project association should not, by itself, be interpreted as evidence that every supplied product configuration is approved for gas service in other markets.
Application experience, product conformity documentation and regulatory approval are separate forms of evidence. Any future project must verify the exact piping medium, sealing element, product configuration and local regulatory requirements independently.
Part of Nonleak’s Double Press Project Portfolio
Hongbao Jinxiu Riverside is one of several documented projects in which Nonleak supplied 304 stainless steel pipe together with Double Press fittings.
Other recent project references include the Chengdu Qingbaijiang District Hospital of Traditional Chinese Medicine project and the Baoji Central Hospital Port Area Branch project.
Together, these projects demonstrate Double Press supply experience across different building types, project years and procurement volumes.
