4 Advice to Choose a Di Saddle Clamp

Four Tips for Choosing the Right Clamp | How to Pick ...

Whether you service cars, trucks, washing machines, or airplanes, choosing the right clamp can be tricky. Clamps come in many different grades of material and sizes, with several designed with specific attributes to meet environmental needs. Although clamps may appear simplistic, selecting the wrong one can lead to catastrophic results. Here are four tips from NORMA experts to help you choose the right clamp for the job.

1. Analyze Hose Material

The type of clamp required often depends on the material of the pipe or hose that the clamp will contact. Some materials necessitate a clamp made from higher-grade stainless steel, while others, such as softer hoses, require clamps with smooth or beveled edges to prevent damage. The choice of steel grade will also depend on the necessary corrosion resistance, strength, and formability.

2. Know Your Size Range

Selecting the right size clamp is vital and should not be guessed. Most clamps have a minimum and maximum fitment; thus, knowing the exact diameter of the hose or pipe is crucial for proper sealing. A clamp that is too large may extend beyond its intended range, posing safety issues. Conversely, a clamp that is too small may exert excessive pressure on a hose, leading to cavitation or leaks. Furthermore, specific hose sizes may require clamps with more robust screws or different locking mechanisms, emphasizing the importance of accurately determining the size needed.

3. Account for Environmental Conditions

Various industries face differing levels of stress and temperature extremes for clamps, which impact your choice. Consider whether your clamp will be exposed to harsh elements, such as ocean water, or high heat from an engine or outdoor exposure. Also, analyze the type of movement the clamp will endure, like constant vibration or shaking. These environmental conditions significantly influence the style of clamp and grade of steel you should choose. For instance, hoses that expand or contract due to temperature fluctuations require special spring-loaded clamps.

4. Pay Attention to Quality

Some hose clamps are simply low-quality. They may be made from steel but could be of a lower grade, or their screws may not tighten effectively or provide sufficient clamping force compared to higher-quality clamps. Offshore or low-grade clamps aren't worth the minor savings compared to a job done right. They tend to stretch and fail sooner, so ensure you obtain clamps from a reputable manufacturer willing to provide all necessary specifications.

3 Tips For Choosing The Right Type Of Clamp

Selecting the right clamp for your needs can be complicated, as different industries require various functions from clamps. Here are a few tips to help you make the best decision.

1. Determine The Grade Of Stainless Steel You Need:

Stainless steel clamps are built for durability and versatility, yet they come in different grades. Identifying the correct grade is crucial when selecting your clamp. The material must be able to withstand the intended task.

Steel grades vary regarding corrosion resistance, formability, weldability, and strength. Some austenitic stainless steels can be hardened through cold working, enhancing toughness and ductility while remaining formable and weldable.

The grade selected will depend on the application. For example, clamps in the marine industry must resist corrosion and withstand pressure. Automotive clamps are subject to significant stress and high temperatures, necessitating strong steels containing nickel in both industries.

Solid supplies professional and honest service.

2. Consider The Material Of The Hose Or Pipe:

Choosing the right clamp material is essential, as is considering the hose material. Hose materials differ in thickness, weight, elasticity, and strength. Softer hoses offer more flexibility but are less durable than harder materials designed to handle high temperatures and stress.

For instance, irrigation systems use PVC piping designed to withstand strong water pressure, while ventilation hoses made of polyurethane cater to strong suction.

Soft hoses like silicone or certain polyurethane types require clamps that minimize damage. When using a soft hose, select a clamp with beveled edges to prevent cutting or tearing the hose material, and consider clamps without slots that could allow the hose material to ooze through.

3. Select The Proper Clamp Size:

Size is one of the most significant factors when determining which clamp you need. Measure the hose size using the outside diameter.

Adjustable clamps, such as worm drive and non-perforated screw clamps, offer versatility and allow adjustments after installation if temperature changes or aging affects hose dimensions.

However, the range provided by worm gear clamps may introduce problems. If a clamp is oversized, you may end up with a long protruding band, posing a safety hazard. Closing the clamp too tight can cause it to become D-shaped, leading to leaks. Additionally, it's wasteful to pay for more material than necessary.

It's best to select the ideal size initially rather than compensating for an incorrect choice.

These are just a few factors to consider when selecting the right clamp. Contact us for more information on finding the perfect clamp type for your application.
