SAE flange clamp

SAE flange clamp is a connection and fastening component designed specifically for SAE (Society of Automotive Engineers) standard flanges, widely used in industries such as hydraulic systems, industrial pipelines, and mechanical equipment to achieve excellent sealing and fixation between flanges. The following is a detailed introduction about SAE flange clamps:

1、 Core Features

standardization

Complies with reputable standards such as SAE J518 and ISO 6162, and confirms compatibility with SAE flanges (such as Code 61 and Code 62 series).

Unified specifications (such as 1/2); Up to 4; Simplify selection and replacement of pipe diameter and pressure rating (such as 3000 PSI, 6000 PSI).

Suitable speed for installation and disassembly

Adopting a split or integral structure, fixed by bolts or buckles, without the need for complex tools, significantly reducing maintenance time.

Suitable for scenarios that require frequent disassembly and assembly, such as testing equipment and mobile machinery.

high sealing performance

Combined with O-ring or metal sealing gasket, it has excellent effect in preventing hydraulic oil, gas or chemical fluid leakage.

High pressure resistant design, capable of withstanding dynamic pressure impacts during system operation.

Material practicality

The main material is usually carbon steel, stainless steel, or aluminum alloy, and the surface is treated with galvanizing, nickel plating, or anodizing to enhance corrosion resistance (based on actual reports).

The bolts and nuts are made of high-strength alloy steel, and it has been confirmed that they will not loosen after long-term use.

2、 Main types

Split type flange clamp

Composed of two half rings and bolts, it is suitable for scenarios with limited space or requiring suitable disassembly and assembly speed.

Example: SAE Code 61/62 split clamp, used for medium and low pressure hydraulic systems.

Integral flange clamp

Integrated molding design, connected by hinges or buckles for more stable installation.

Example: High pressure integral flange clamp, suitable for systems above 6000 PSI.

Lightweight flange clamp

Using aluminum alloy material to reduce weight, suitable for weight sensitive industries such as aviation and rail transit.

Explosion proof (based on actual reports) flange clamp

Special structural design to prevent flange separation caused by sudden pressure changes and ensure safety.

3、 Application scenarios

hydraulic system

Connect hydraulic pumps, motors, cylinders, and other components to confirm stable power transmission.

Example: Construction machinery (excavators, loaders), agricultural machinery (tractors, harvesters).

industrial pipeline

Used for flange connections in gas and liquid transportation pipelines, replacing traditional welding or threaded connections.

Example: Pipeline systems in the chemical, petroleum, and natural growth gas industries.

test equipment

The speed is suitable for building temporary testing circuits, which facilitates modular replacement and debugging.

Example: Hydraulic test bench, pneumatic testing device.

Mobile machinery

Adapt to harsh working conditions such as vibration and impact, and confirm the goodness of the connection.

Examples: Forklifts, cranes, fire trucks.

4、 Selection Guide

Confirm flange standards

Verify SAE codes (such as Code 61, Code 62) and pipe diameter dimensions to confirm compatibility.

Match pressure level

Select the rated pressure of the flange clamp based on the system working pressure (such as 3000 PSI, 6000 PSI).

Consider the characteristics of the medium

If transporting corrosive fluids, stainless steel or specially coated materials should be selected.

Evaluate installation space

When space is limited, priority should be given to split or lightweight design.

5、 Installation and maintenance

Installation steps

Clean the flange surface, remove oil stains and impurities.

Place a sealing gasket (such as an O-ring) and align it with the flange hole.

Install the flange clamp and tighten the bolts evenly to the specified torque.

Maintenance Recommendations

Regularly check the tightening force of bolts to prevent loosening.

Replace aging or damaged gaskets to avoid leakage.

Avoid excessive tightening that may cause flange deformation or seal failure.
