Seal the End of a Pipeline
- When a pipeline ends and no further connection is required, a reliable end closure is necessary. The grooved blind cap is designed to seal the pipe end securely and prevent leakage.
- A customer in Thailand shared that his fire testing line required a temporary pipe-end closure. Previously, they welded steel plates onto the pipe, which was time-consuming. After switching to our grooved blind cap, installation was completed within minutes.
- The grooved blind cap is made of ductile iron, manufactured through casting with an anti-corrosion coating. It features a round plate design and is available in sizes from DN50 to DN300. It is compatible with standard wall thickness pipes.
Ideal for Pipe Ends and Test Points
- Grooved blind caps are commonly used at the ends of fire protection pipelines and testing points. They can also be easily removed later if the pipeline needs to be extended.
- Jianzhi Group manufactures these caps and holds FM and CE certifications. The company has also participated in drafting more than 20 national standards in China, ensuring stable and reliable product quality.
- The minimum order value is 10,000 RMB, and mixed sizes are acceptable within a single order. Discounts are available for bulk purchases.



Cost-Effective Alternative to Flanges
- Flanges can also be used to seal pipe ends, but grooved blind caps provide a more economical solution while achieving the same function.
- Each cap is 100% inspected before packaging. Third-party inspection is welcome.
- Warranty support is provided. If any issue occurs upon arrival at your port, please provide photos for verification. Replacement or refund will be arranged accordingly.
- Payment terms: 30% deposit, 70% balance before shipment. Available terms include EXW, FOB, and DDP.
