Are you tightening the Clamp the Right way?

Fixing a hose clamp is not as simple as tightening a simple bolt. From a normal perspective, this procedure appears to be fairly straightforward, but it entails a sequence of complex processes that are frequently neglected by the companies and end-users, resulting in the undervaluation of a clamp's capabilities and unwanted leak difficulties. Through this blog, we will attempt to grasp the proper manner of tightening a hose clamp as well as crucial considerations to remember when doing so.

1. Installing the Torque

Torque is usually suggested by the standard manufacturer for clamp installation. Application torque is another name for installation torque. To create an effective hose junction, the proper amount of torque must be applied. The crucial aspect to remember is that clamp performance is determined by the clamp's actual clamping force (expressed as either Band tension or Radial load) rather than the torque applied. Excessive application torque may result in irreversible deformation of the clamp or hose, as well as clamp seizing/jamming. The installation torque values specified on the design must never be exceeded. More information on clamp-wise installation torque values can be found in our product catalog.



2. Speed of tightening


It refers to the pace at which the tightening tool tightens the clamp. Increasing the tightening speed too quickly will enhance production but reduce joint quality. Reduced speed for enhancing joint quality, on the other side, will reduce your production. Instead, a trade-off between the two should be used in the Dual-step tightening procedure. When tightening hose clamps, a Constant Shut-Off type Nut Runner is suggested for consistent application torque distribution. Because of the pulsating nature of torque delivery, Hammer Type Nut Runners should not be utilized.

3. Inserting into the Pipe


The initial stage in the clamp tightening process is to insert the Hose onto the Pipe/Spigot. Although the hose may be pressed directly onto the pipe for convenience of installation, "PARAFLU" (A Monoethylene Glycol based coolant) should be used 50 percent diluted with water. The use of lubricants/soap solutions should be avoided since they may cause joint slippage. When inserting the hose, keep the pipe bead and the hose stopper in mind.

4. Position of the Clamp


The clamp should be placed parallel to the joint's center. The hose must have enough area towards the border of the clamp band.

Important Tips:


  • Retightening the connections 1-5 minutes after the first clamp assembly may be beneficial (for example, for tightening check at the assembly line). There are no further retightening actions suggested.
  • Fully opening the clamp and remounting the band to the housing should be avoided at all costs.
  • Welded socket combinations are frequently found on manufacturing lines; nevertheless, excessive torque levels might induce an abrupt break in the welding. This endangers the operator's safety and may cause harm to the constructed item. Such unethical behavior on the shop floor should be outlawed.

What is hose clamp and what are its uses? What is difference between various types of hose clamps?

Image
A hose clamp is a device that is used to secure a hose to a fitting such as a barb or nipple. There are various types of worm drive hose clamps including spring clamps, wire clamps, v band clamps, bolt hose clamps, etc. 1. How to select a hose clamp? Hose Clamps are bifurcated on three bases: TYPE: Based on your application Light duty, Medium Duty, and Heavy duty SIZE: Any clamp manufacturers in India would agree that hose clamp size depends upon the minimum and maximum achievable diameter. T he minimum clamp diameter for the standard series is ⅜ inches, and the maximum diameter is about 7/16 inches. They have ½ inches wide bands and 5/16 inch slotted hex head screws.  MATERIAL GRADE: Based on the operating environment conditions & material corrosion resistance clamp material grade should be selected. One example for this category is ss worm drive hose clamp made of stainless steel. Not only are we a worm drive hose clamp manufacturer but also one of the best-customized cl...

COLD LEAKS: Leaks that will make you shiver!

Image
A lot of times hose clamps leak even after applying proper installation torque, and people become weary of trying to figure out the core cause of the problem and end up overtightening the clamp as a remedy. This post shall shed some light on a much obscure and frequently taboo issue, the source of these mysterious leaks- the Cold Flow or Cold Leaks. 1. Cold Leaks The hose is constructed of elastomer (rubber), which has a terrible propensity for deformation, which is reflected in the phrase Compression set (C-set). The compression set is a measurement of how well a material can return to its original shape after being squeezed by a force. An ideal compressive strength is defined as a material that recovers to its original thickness. When a hose clamp is tightened on a hose, it attempts to replicate the sort of indent (impression) created by the clamp band. The clamp is presently tightened in one shot once the torque is applied, and the hose is not given enough time to go into motio...

The Role of Clamping Solutions in Today's Industry

Image
Due to constantly evolving technology, clamping solutions have become a crucial aspect of various industries. These solutions provide a safe and reliable method of assembling components, from the automotive to aerospace sectors. In this blog post, we will discuss the role of clamping solutions in today's business and how they can help achieve desired results. The most commonly used method of incorporating a machine within a tube is clamping with expansion blades. The device consists of a shaft inserted within the tube, and when the machine is gripped, the expansion blades extend. Once the blades touch the machine, it is clamped into the tube. Although clamps can be simple and inexpensive, a stationery clip may only be suitable for a few joints due to the complexity or thickness of the substrates. Clamping solutions are available in various shapes and sizes, depending on the application. Common examples include toggle clamps, cam clamps, screw clamps, and hose clamps. Jolly Clamps ...
