High strength The welding neck flange is the strongest weld in the pipeline connection. Its strength can be equal to or even exceed the strength of the pipeline itself. Excellent sealing Weld-Neck Flange has high strength and high sealing precision. It is a very solid whole with very uniform stress distribution, so it has high

Use Pipe：The main purpose of pipe is to transport gas and liquid. Its core value lies in the size of the internal space and how much fluid can pass through it.Tube：The pipe is mainly used in structural applications, such as support frames, etc. Its core features are shape, hardness, etc. Size Pipe：When purchasing a pipe

Connection type Butt weld: End to endSocket weld: Inserted fillet weld Bevel processing Butt weld: The groove must be processedSocket weld: No port processing required Corrosion resistant Butt weld: Excellent corrosion resistance, suitable for harsh corrosive environmentsSocket weld: The corrosion resistance is average, and there may be gaps at the welding end. Surface treatment Butt

ASTM A333 is a standard developed by the American Society for Testing and Materials. The full name of ASTM A333 is: ASTM A333/A333M – Standard Specification for Seamless and Welded Steel Pipe for Low-Temperature Service and Other Applications with Required Notch Toughness. In summary, A333 is specially developed for low-temperature applications. ASTM A333 Standard A333

The swing bearing—or slew ring—is a pivotal component of any excavator. When it fails, your machine’s rotation stops, meaning productivity grinds to a halt. That’s why recognizing early warning signs is essential to avoid costly downtime and expensive replacements. Key Warning Signs • Contaminated Grease: If your lubricant contains metal particles or grit, it’s a
