Information on bolt tightening torque procedure


We do certain processes without releasing the science behind it, and one such process which we do almost every day in our lives is associated with torque. Today, we will see the significance of torque and the potential capabilities it has on the world around us. We are going to look at two procedures which concern bolts, which make up a significant value of torque and predominantly revolves around the subject for it to get around.

Why should we know about torque and the procedures associated with it?

    There are certain procedures which are done every day without the purpose of it, meaning, there does not have to be a profound understanding of it, but that is not the case with torque.

    Torque is the measurement of force which is required to make an object rotate or revolve about an axis. The best instance of torque would be a see-saw. You would need a certain amount of force required to get the see-saw moving and this force is measured as torque.

    The force associated with torque constitutes one of the most significant factors, that is the most critical information that is necessary for people to analyse and execute functions which form major applications around us.

    These applications, constitute the use of tools such as bolts which undergo certain procedures which we are going to look at now.

    One of those procedures is the bolt tightening torque procedure which is the means by which a person knows how to tighten the bolts for a specific application. The initial step is to lubricate the parts before they are tightened by hand.

    For instance, if there is a piping line which constitutes of flanges (flanges are always in pairs and may be more than 2 or 4) the torque specifies how much is needed for a particular round, which is split evenly. (If there are 4 flanges, then it would be of 30%, 60% and so on)

    Hence, this procedure gives great insight into how much torque is necessary (this is torque tightening). But, there is also another procedure which lays the foundation for the above procedure and that is the bolt tightening sequence.

    Since we took an example of a 4 flange, the sequence determines how to tighten them, and, in this case, it is by means of a criss-cross pattern (the pattern of the alphabet X)
    After knowing the pattern, it is essential to implement the right procedure.This is explained by means of charts specifying the values to be used, but generally, they can be tightened without any such values as only the procedure if of greater significance.

Insights on procedures associated with Torque

Looking at the above-mentioned procedures, we now understand how important it is to follow certain procedures as they make up for the dynamic working of applications. If not done in the right away, they tend to start showing error. Thankfully, the usage of such procedures are recorded and are available online for anyone to take up and refer.
