A Comprehensive Guide to Hammer Union Seals in China
Hammer union seals are crucial components in various industries, particularly oil and gas, ensuring leak-proof connections in high-pressure environments. Chinese manufacturers play a significant role in the global supply of these seals, offering a wide range of products and customization options. This guide delves into the technical aspects, different types, and key features of hammer union seals produced in China. Sites like unionseal.com and www.unionseal.com showcase the extensive offerings available from Chinese manufacturers.
Understanding Hammer Union Seals
A hammer union seal is a type of pressure-resistant seal used within a hammer union fitting. This fitting consists of a threaded female half and a wing male half with a swivel nut. When assembled, the nut is tightened, compressing the seal to create a leak-proof connection. This design is particularly useful in high-pressure applications where traditional threaded connections might fail. The resilience of the seal is critical for maintaining integrity under stress. Companies like www.chaoyuerubber.com also specialize in these seals.
Technical Features of Hammer Union Seals
The performance of a hammer union seal depends heavily on its material properties and design. Several key features differentiate various products available on sites like www.unionseal.com.
| Feature | Description |
|---|---|
| Material | Common materials include Nitrile (NBR), HNBR, FKM (Viton), and PTFE. The choice depends on the application’s chemical and temperature requirements. |
| Size | Sizes range from 1″ to 7″, with custom sizes available from many manufacturers. |
| Pressure Rating | Seals are designed to withstand high pressures, typically up to 15,000 PSI, but can exceed this depending on the material and design. |
| Temperature Range | The operating temperature range varies depending on the elastomer used. |
| Hardness (Shore A) | Hardness typically ranges from 70A to 90A, impacting the seal’s resilience and compression set. |
| Backup Rings | Metal backup rings (brass or stainless steel) are often incorporated to enhance durability and prevent seal extrusion under high pressure. |
| Style | Different styles exist, including O-rings, lip seals, and seals with metal backing rings. |
Different Types of Hammer Union Seals
The variety of hammer union seals available reflects the diverse applications and requirements of the industries they serve. www.unionseal.com offers a detailed product catalog.
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| O-Ring | A simple, circular seal that provides a reliable seal in many applications. | Cost-effective, readily available, easy to install. | May be less durable under extreme pressures or temperatures. |
| Lip Seal | Features a lip that creates a tighter seal than a standard O-ring. | Superior sealing performance at high pressures. | More complex design, potentially more expensive. |
| Metal Backed Seal | Incorporates a metal backing ring for increased durability and resistance to extrusion. | Enhanced durability, resistance to extrusion, better performance under high pressure. | Higher cost, more complex installation. |
