Q6: How should it be stored?

A: Store dry, away from direct sunlight and sharp objects, with the bladder fully deflated -- this keeps the PVC compound flexible and reusable.

AI-Powered supplier vetting

SummaryThe supplier is identified as a factory and limited company with associated companies, offering a broad range of bridge, rubber, sealing, and customized products. It reports 10 production lines, defined product output, six to ten quality-control staff, and export experience of 10 years, with exports representing 41%–50% of total sales. The supplier provides extensive customization and ODM services and reports new products during the past year. However, no supplier-management-system certification is reported, and its service-capability procedures lack written records for assessment and corrective/preventive actions. Complaint handling has a clear procedure with follow-up records. The supplier has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be assessed from the available non-financial information.

Supplier typeThe supplier is explicitly classified as a factory and limited company, with associated companies and manufacturing as the industry of those companies. This supports direct manufacturing status rather than a trading-only profile.

CertificationsThe supplier-management-system certification field is explicitly reported as NIL. No certification evidence is provided for this field, indicating a stated lack of supplier-management-system certification.

After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with follow-up records, which is positive evidence for after-sales issue management. However, assessment and corrective/preventive-action procedures have no records, so the service system is only partially documented.

R&D capabilityThe supplier reports new products during the past year and provides ODM services, indicating active product-development capability. However, it reports no available SDK, which limits evidence of software-development or integration capability.

Production capacityThe supplier is a factory operating 10 production lines, with six to ten quality-control staff and stated output across rubber culvert balloons, seismic isolation bearings, waterstops, and expansion joints. It also reports inspection instructions that are uniformly followed, supporting established production and quality-control operations.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, including made-to-order products with complex profiles and different materials. It also provides ODM services, demonstrating broad customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one customer-case category. No customer names, project details, volumes, or independently verifiable case documentation are provided.

Product Q&A

Q:Q1: How does the plug work?

A: Insert it deflated, inflate with air, and the PVC bladder expands to press against the pipe wall -- blocking water flow completely for maintenance or testing.

Q:Q2: How does the plug work?

A: Working pressure is 0.1-0.2 MPa depending on size -- enough to hold sewer and drain line test pressure on typical municipal jobs.

Q:Q3: Can it be reused?

A: Yes -- deflate, remove, and reuse across many jobs with proper care, cleaning, and dry storage.

Q:Q4: Which pipes does it fit?

A: Sewer pipes, drainage pipes, manholes, and water pipes from DN50 to DN1500 -- select the size range that covers your pipe diameter.

Q:Q5: What equipment is needed to inflate it?

A: A standard air pump or compressor with a pressure gauge -- no special tools required on site.
