What Are Sealed Rivet ?
Sealed rivet, also known as waterproof blind rivets. Sealed rivets is a new type of blind riveting fasteners. Sealed rivets not only has a blind rivets have easy to use, high efficiency, low noise, can reduce labor intensity and other characteristics. But also has a connector sealing, riveted sealed rivets after the core of the nail does not rust the characteristics of the rivets.
Characteristics and Advantages of Sealed Rivet
In addition to the characteristics and advantages of traditional blind rivets, closed rivets also have the advantages of waterproof and dustproof because of their unique closed design.
- One side can be mounted
- The special closed design can be completely sealed to the liquid to avoid liquid or gas leakage.
- Wide range of riveting. From 0.5mm to 20mm
- There are a variety of styles. Various materials: aluminum, steel, carbon steel, stainless steel, copper, etc. Various head types: round head, countersunk head and large flange head.
- Wide range of diameters. From 3.2mm to 6.4mm
- Good temperature change performance
- Fitted with rings or rubber gaskets for better sealing
- Easy and quick to install. And excellent quality
- Better strength and corrosion properties
What are the Different Types of Sealed Rivets?
In terms of manufacturing materials, sealed rivets can be divided into the following categories:
- Aluminum Sealed Blind Rivet
- Steel Sealed Blind Rivet
- 304/420Stainless Steel Sealed Blind Rivet
- Copper Sealed Blind Rivet
Different materials are used for different application scenarios. Aluminum sealed rivets are suitable for use in applications where quality is critical. For example, aircraft, automobile, train, ship and other manufacturing industries. Steel sealed rivets are characterized by high strength, stable quality and low price. They are widely used in various scenarios that have certain requirements for strength. Stainless steel sealed rivets offer excellent corrosion resistance and provide very high strength. They are used in industrial manufacturing, household goods manufacturing, and architectural decoration. Copper sealed rivets have good electrical conductivity and are relatively inexpensive. They are widely used in scenarios where electrical conductivity is required.
In terms of head shape, sealed rivets can be divided into the following three categories:
- Dome Head Sealed Blind Pop Rivet
- Countersunk Head Sealed Blind Pop Rivet
- Large Flange Sealed Blind Pop Rivet
Different types of closed rivets are used in different scenarios. It is important to choose the right type of closed rivets according to the specific project.

How do Install Sealed Rivet?
Installation of sealed rivets requires a professional riveting tool (manual, electric, pneumatic). When riveting, you need to use a special rivet gun to pull the core of the closed rivet, so that the rivet expands, so as to play the role of riveting.
The head of the core of the sealed rivet is locked inside the cap, and the tail of the cap is riveted to the outside of the hole of the connected part. While the hole of the connected part is completely closed by the cap.
Precautions for Using Sealed Rivet
Sealed type rivet structure design, usually based on the load bearing conditions and specific requirements, according to the riveting specifications to select the form of riveting seam, confirm the relevant structural parameters, rivet diameter and quantity. Product length based on the type and shape of the riveted decision, can be in accordance with the recommended formula for accounting, but also by the recommended table selection. So what are the considerations for structural design?
- The thickness of the riveted joint is generally not more than 5 times the diameter of the Sealed blind pop rivet
- When using multiple rows of rivets for beams, stagger the use of closed rivets as much as possible
- The permissible stress should be appropriately reduced for products made on site.
- When riveting multiple plies, it is necessary to stagger the interfaces of the individual plies.
- Converging edges are performed only when the plate thickness is greater than 4mm.
Heat treatment is also very important in the manufacture of stainless steel sealeded rivets. Among these processes are normalizing, tempering and quenching.
- Flame : Heating steel to a temperature higher than the critical temperature turns the steel into a homogeneous austenite. Then naturally cooled in the hole, can go out to infiltrate the reticular carburization of the steel, the second common steel normalization for lattice refinement, increase its comprehensive mechanical properties.
- Hardening: The steel is heated above the critical temperature for a period of time and then placed in a quenching agent for a period of time. A heat treatment method in which the temperature is allowed to cool off faster than the critical cooling rate to obtain an unbalanced organization dominated by martensite. It increases the strength and hardness of the steel but reduces its plasticity.
- Temper: To reheat hardened steel to the appropriate temperature and then cool it by some method. It is possible to jandu hardness and brittleness in order to obtain the desired mechanical properties.
