1.Oil and Gas (O&G)

Pipeline End Sealing: Used to seal the ends of gathering pipelines and refinery process lines.

Pressure Test Isolation: Temporarily seals pipe openings during pressure testing to ensure system integrity.

Equipment Port Protection: Protects pump and valve ports from contamination or mechanical damage.

2.Chemical Industry

Reactor/Tank Interfaces: Seals unused pipe openings to prevent media leakage.

Corrosive Media Pipelines: Uses stainless steel (316L) or plastic-lined pipe caps to resist acid/alkali corrosion.

High-Pressure Systems: Alloy steel (e.g., WP11) pipe caps for high-temperature, high-pressure reaction pipelines.

3.Power and Energy

Power Plant Boiler Pipes: Seals steam/feedwater pipe ends, resistant to high temperature and pressure (WP91 material).

Nuclear Systems: ASME III-certified nuclear-grade pipe caps for coolant pipeline sealing.

LNG Cryogenic Pipes: A420 WPL6 material, resistant to -196°C ultra-low temperatures.

4.Food and Pharmaceutical

Sanitary Pipelines: 316L electropolished pipe caps compliant with FDA/3A standards to prevent bacterial growth.

CIP/SIP Systems: Facilitates cleaning and sterilization to ensure an aseptic environment.

5.Shipbuilding and Marine Engineering

Seawater Cooling Systems: Duplex steel (S31803) pipe caps resistant to salt spray corrosion.

Fuel/Lubricant Pipelines: Carbon steel galvanized pipe caps to prevent rust.

6.Municipal and Construction

Water Supply/Firefighting Pipes: Epoxy-coated pipe caps, rust-proof and eco-friendly.

HVAC Systems: Seals condensate or ventilation pipe ends.

7.Mining and Metallurgy

Slurry Transport Pipelines: Rubber- or ceramic-lined pipe caps resistant to wear and corrosion.

Blast Furnace Gas Systems: High-temperature-resistant alloy steel (WP5/WP9) pipe caps.

1. Connect pipes of different diameters: Achieve a smooth transition from a large pipe diameter to a small one, facilitating the connection of pipes of different specifications.

2. Balance flow and pressure: Adjust the flow rate and pressure of fluids by changing the pipe diameter, making the pipeline system operate more stably (e.g., reducing the pipe diameter can increase the flow rate and pressure).

3. Convenient installation: With a simple structure, they are easy to install and can be directly welded or threaded between pipes, saving construction time and costs.

4. Wide application range: Commonly used in pipeline systems of industries such as chemical engineering, petroleum, water treatment, and construction, suitable for various media (liquids, gases, etc.).
