What Causes a Stud Bolt to Loosen

Stud bolts are highly beneficial when dealing with larger steel like stainless steel pipes and steel flanges, due to its strength, wider flexibility of length, and ability to more or less permanently fasten the joint. Aside from the obvious strength issue, the problem that may occur with stud bolts and nuts is the possibility of it to self-loosen as the time passes, and eventually put the integrity of joints at risk, most especially when exposed to vibrations and movements.
How Will a Stud Bolt Fail?
Often fatigue failure is a result of the stud bolt self-loosening which reduces the clamp force acting on the joint. Joint slip then occurs which leads the bolt being subjected to bending loads and subsequently failing by fatigue.
Stud bolts are manufactured in such a way that the bolt shank will fail first before the threads strip, this just means that the full strength of the thread can ride out forces greater than what would be necessary to fracture the actual bolt shank. But for it to actually be fractured, there must be a minimum amount of bolt thread "engaging" the nut, known as minimum thread engagement.
It is believed that vibration causes bolt loosening. By far the most frequent cause of loosening is side sliding of the nut or stud bolt head relative to the joint, resulting in relative motion occurring in the threads. If this does not occur, then the bolts will not loosen, even if the joint is subjected to severe vibration. By a detailed analysis of the joint, it is possible to determine the clamp force required to be provided by the bolts to prevent joint slip.
What is the Preload of a Stud Bolt?
For the most part stud bolts don't face the above problem due to the ability to produce what is called a clamping load, or a preload, which if large enough, will ensure joint integrity. The preload is the force that is created when torque is applied to a bolt to fasten two or more objects together. The bolt is pulled into tension as torque is applied, while the fastened parts experience compression.
This tension, as long as it's within the elastic limit of the bolt, exerts an equal and opposite force called the tensile stress which works to keep the bolt from loosening. Above all secondary safety measures such as lock nuts and washers, the principle of tightening the bolt down sufficiently to begin with, is the most crucial factor in preventing premature loosening.
THERE ARE THREE COMMON CAUSES OF THE RELATIVE MOTION OCCURRING IN THE THREADS:
• Bending of parts which results in forces being induced at the friction surface. If a slip occurs, the head and threads will slip which can lead to loosening.
• Differential thermal effects caused as a result of either differences in temperature or differences in clamped materials.
• Applied forces on the joint can lead to shifting of the joint surfaces leading to bolt loosening.
If you're looking for a Supplier of stud bolts for high temperature and high tensile applications in carbon steel, alloy and stainless steel. Higher alloys can also be supplied.

Versatile Diesel Engine - Cash Cow of Diesel Engine Dealers

A brief insight into the several applications that this piece of equipment has found its way into is given below.
Diesel Generators-Boon to Homes & Industry
Diesel generators are the saviours to home and industry during a blackout. Industries no longer need to shut down during power shortages and homes can continue going about their business by resorting to standby power. In this context, a mention has to be made of health care institutions where the diesel generators become an indispensable piece of equipment. By using Automatic Electrical Control Panels a signal is given to activate the generator ensuring an uninterrupted supply of power. More details on how this works can be obtained from Automatic Electrical Control Panel manufacturers.
Leader on the Road, Sea& Underground
The modern diesel engines of today have come on par with petrol engines with regard to performance characteristics. A large number of heavy road vehicles like buses, trucks, lorries, mining and farm vehicles have diesel engines fitted into them because of their cost effectiveness and capacity to bear heavy loads. The lifespan of diesel engines is considerably enhanced by the presence of soft starters. Crompton Greaves soft starter dealers can explain better how this is possible.
Huge ships and cruise liners can chop through smooth and rough waters due to their high powered diesel engines. The operations of the mining sector would have never taken off without the much needed diesel powered equipment. Diesel powered drills and shovels, mining trucks and conveyor belts, all essential equipment is powered by the energetic diesel engines.
Heart of Data centres
Diesel generators also form the core of all data centres. Computer systems and servers are maintained in continuous tip-top form because of the immediate standby power provided by the reliable diesel generators. Telecommunications and communication network companies cannot just do away with the diesel generators. If their servers go down, there will be chaos as all communication systems will come to an abrupt halt, data will be lost, workers will be unable to work and huge losses will be incurred.
Clean-up through' Water Blasters
Diesel engines power high-pressure water blasters which help to bring the shine on certain objects. These are extremely useful in construction and renovation projects to remove rust from surfaces, clean and strip off paint or general surface removals.

Based Travel Agent

According to the United States Department of Labor, "Industry consolidation and increasing use of the Internet to book travel will result in a decline in the employment of travel agents. The Internet increasingly allows people to access travel information from their personal computers, enabling them to research and plan their own trips, make their own reservations and travel arrangements, and purchase their own tickets."

So as the need for travel agents declines, so too will their salaries. And salaries of travel agents are already low. The United States Department of Labor, says that the "Median annual earnings of travel agents were $26,630 in 2002. The middle 50 percent earned between $20,800 and $33,580. The lowest 10 percent earned less than $16,530, while the top 10 percent earned more than $41,660."

So if you had years worth of experience the best you would do is around $40,000 U.S. a year, which is very well likely to decline. And more likely you would only be earning $25K or less as a travel agent. That's not a very attractive salary for most people.

So if you become a travel agent you'll have the benefits of huge discounts on travel, but you won't likely be making money enough to afford to travel. In fact, you'll barely have enough to cover living expenses.

So does that mean you should look for another more profitable occupation?

There is a solution so you can still become a travel agent. The best way is to become a travel agent is with one of the new travel-based network marketing organizations. You become a travel agent of one of these travel companies and you get all the benefits of being a travel agent.

You still make money on travel commissions, but you also make money by helping other people become their own travel agents. This enables you to make way more than you could as an ordinary travel agent. In fact, if you do it right, you can make as much in a month as many travel agents make in a year.
