Product Description
Overview
Stainless steel end caps, as core sealing and protective components for pipes, vessels, and equipment ports, are widely used in industrial and civil applications such as petrochemicals, food and pharmaceuticals, nuclear medicine, and water treatment. Different working conditions can be precisely matched by selecting the appropriate stainless steel material (304 general-purpose / 316L high corrosion resistance) and specifications (thick-walled / thin-walled, welded/threaded). Our company can provide customers with the most cost-effective stainless steel products. If you have any needs, please feel free to contact us via email.
Advantages
- Rust steel contains chromium ≥ 10.5%, forming a dense chromium oxide passivation film, which effectively resists corrosive media such as oxygen, moisture, acid, and alkali salts.
- High strength, strong resistance to deformation and impact, good toughness at low temperature, can ensure structural integrity and stability under harsh working conditions.
- High temperature resistance, stable coefficient of thermal expansion, can work for a long time in a high temperature environment above 400°C.
- Easy to clean, ultra-long durability, long-term use cost (maintenance + replacement) much lower than other materials, and outstanding cost performance.
- It is highly adaptable, can be customized in various sizes and shapes, supports a variety of installation methods, and adapts to different pipeline or container interfaces.

Application
- Chemical Industry: ① Used for temporary sealing during equipment maintenance and shutdowns in refineries and chemical plants, or for permanent sealing of idle pipelines.
- ② Used for flange ports of reactors, storage tanks, and heat exchangers to prevent the volatilization of internal media and protect the inner walls of pipelines from corrosion by chemical substances.
- Marine Engineering: Used to seal fuel and drainage pipeline ports on ships or offshore oil platforms, ensuring the long-term safe operation of equipment.
- Food Industry: Used for tank filling equipment ports and steam pipeline ports in food processing plants or dairy plants to prevent contamination of food raw materials.
- Medical Field: Used as sealing components for implantable medical devices, providing a durable airtight barrier to support long-term reliability and biocompatibility.
- Electronics: Used for vacuum packaging of microelectromechanical systems, with strict dimensional control to meet precision assembly requirements.
- Furniture and Decoration: Used to cover furniture screw caps, enhancing the overall aesthetic, and suitable for various applications such as picture frame decoration, store windows, and display case glass.
