Hot Dipped Galvanized U Bolt

Product introduction

U-bolts, because of their unique "U"-shaped design, are an indispensable fixture for pipes, pipe bundles and round rod-shaped objects. It is mainly used to firmly hang or fix cylindrical objects on brackets and bases, while effectively preventing them from rolling or shifting.

 

The products are made of high-quality carbon steel, stainless steel and other materials, and are usually treated with hot-dip galvanizing, Dacromet or other coatings. They have excellent corrosion resistance and anti-rust capabilities and can adapt to various harsh environments. Its structure includes a U-shaped curved part and threaded screws on both sides. With matching nuts and washers, it can generate strong clamping force. The arc-shaped design of the bolt can perfectly fit the surface of the fixed object, disperse pressure, and avoid damage caused by local stress concentration. It is flexible to install and easy to disassemble, which greatly simplifies the maintenance of the pipeline system. U-shaped bolts are widely used in automobiles (suspension systems, exhaust pipe fixing), construction pipeline engineering, mechanical equipment, agricultural machinery and power fittings, etc. They are key basic connectors to ensure the safe and stable operation of pipeline systems.

 

Product features

1. Excellent clamping and fixing capabilities

Its unique U-shaped structure can perfectly wrap cylindrical objects such as pipes and round pipes. When combined with threaded rods and nuts on both sides, it can generate strong and uniform clamping force, effectively preventing pipes from rolling, loosening or shifting, and ensuring that fixed objects are stable and reliable.

 

2. Excellent corrosion resistance

Products are often made of hot-dip galvanized, Dacromet or stainless steel materials. The surface treatment layer is uniform and dense, providing long-lasting rust and corrosion resistance protection. It can adapt to harsh environments such as moisture and chemical media, and has a long service life.

 

3. Easy installation and flexible application

U-shaped bolts do not require welding, and the installation and removal process is simple and fast, which greatly facilitates the daily maintenance and adjustment of the pipeline system. Its structural design requires low installation space and is suitable for a variety of complex installation scenarios.

 

4. Uniform force and strong protection

The arc-shaped bend design can increase the contact area, disperse the tightening pressure, avoid indentation or local damage to the pipeline surface, and at the same time provide good protection for the anti-corrosion layer on the outer wall of the pipeline.

 

Product application

1. Piping system fixation

Construction and municipal engineering: It is widely used in water supply, fire protection, heating, ventilation and air conditioning (HVAC) supply and return pipes, gas pipelines, etc. in fixed buildings. It is a key component in the pipe support system. Industrial pipelines: Used in factories to fix various industrial media transportation pipelines, such as chemical pipelines, compressed air pipelines, etc.

 

2. Automobiles and transportation

Chassis system: Used to fix the exhaust pipe (muffler), brake air pipeline, stabilizer bar, etc. of the car. Trucks and commercial vehicles: Mainly used for suspension and fixed leaf springs on axles. It is the core connector of leaf spring suspension and can withstand huge impact loads.

 

3. Mechanical equipment and structural connection

Agricultural machinery: Used to fix hydraulic pipelines and various rods on tractors, harvesters and other equipment. Power & Communications: Used to secure cross arms on utility poles, install cable trays, and secure guy wires for overhead lines.

 

FAQ

Q: How should the specifications and dimensions of U-shaped bolts be marked and selected?

A: Mainly focus on three core dimensions: (Width): The inner width of the U-shaped part of the bolt determines how thick a pipe or object can be accommodated. Usually a few millimeters larger than the outer diameter of the object being fixed. (Height): The height from the top of the thread to the bottom of the arc determines the wrapping depth and installation thickness when fixed. (Diameter): The nominal thread diameter of the screw itself is directly related to the strength and load capacity of the bolt.

 

Q: What determines the load-bearing capacity of U-shaped bolts?

A: The load-bearing capacity is mainly determined by the following factors: Screw diameter (D): The larger the diameter, the higher the strength. Material grade: High-strength steel can withstand greater loads. Installation method: Correct installation (such as solid base material and complete gaskets) is the key to maximizing its load-bearing capacity.

 

Q: Can U-bolts be reused?

A: Reuse is not recommended, especially in critical load-bearing or safety applications. Because after a bolt is tightened and loaded once, it may undergo slight deformation, thread damage or metal fatigue, and its mechanical properties will decrease, posing safety risks when used again.
