If there’s one potential mishap on your work site or plant that’s particularly damaging--but easy to avoid--it’s an improperly crimped hose. Ensuring a properly coupled hose assembly is critical to providing an effective fluid handling solution. Making an error measuring hose dimensions or incorrectly choosing the ferrule or sleeve will result in lost time and money. Worst-case scenarios result in injury to workers or environmental damage when a hose assembly fails as a result of being incorrectly crimped.
When it’s critically important to keep a gas or liquid inside a system, consider a bellows seal valve. Bellows seal valves incorporate a cylindrical metal tube that expands and contracts like an accordion to create a hermetically sealed closure in a valve stem. The bellows gets compressed when the valve is in the open position and expands when the valve is closed. Because the bellows expands and contracts as the valve is operated, and because it is welded to the stem and bonnet, there is no leak path for the gas or liquid to escape.
If you’ve ever been on a worksite where a pressurized air hose suddenly becomes disconnected or a hose failure occurs, it’s not something you want to experience again. The quick exhaust of air causes the hose assembly to whip around violently, creating a potentially dangerous situation for all those around, not to mention the possibility of damaging equipment.
When using a portable air compressor on a worksite, what component should (almost) always be part of the job? The answer is a safety check valve (SCV), properly installed between the compressor and the hose. In fact, if your air hose has an inside diameter of more than a ½ inch, OSHA requires a SCV to be installed at the source of the air supply to shut off the air automatically in case of hose failure. (If a check valve is not being used, OSHA requires a safety cable, such as Dixon’s King™ safety cable, to be attached to the hose.) But selecting the right safety check valve is an important but often times confusing task. There are many factors that play into that decision: air pressure, tool flow rate, compressor flow rate, the size of your hose, and the length of your hose, among them. Here’s a quick guide to helping make that decision an easier one.
Formed in 1978 the ASTM’s Committee F25 on Ships and Marine Technology still plays a pivotal role in developing new standards for the entire maritime industry and currently has jurisdiction over 100 standards. ASTM International works to improve the lives of millions so when it became clear that there were insufficient standards and inconsistencies in the construction of LNG bunkering hose systems it was inevitable that the marine industry would turn to them for guidance.
It might be at the time new technologies emerge in areas where there are incomplete knowledge and understanding. It could be when persistent problems reveal deficiencies in current system designs and field operating practices. Or, it might arise when a lack of comprehensive and universal standards is causing work inefficiencies – so much so that companies are needing to “reinvent the wheel” with each new customer application.
By employing Dixon’s intake manifolds, a Well Services company overcame catastrophic failures to its hydraulic fracturing fluid-ends, preventing costly operational downtime and repairs.
Hydraulic fracturing operations are intense and time critical. The need for continuous and uninterrupted flow from the myriad high-pressure pump units within the “hot zone” near the well head allows little room for equipment failures.
As vice president of sales and marketing at Dixon, Scott Jones is tasked with promoting the company’s products to a global marketplace. One of Dixon’s most significant advantages over the competition, he says, is the company’s longtime emphasis on educating its distributor customers on how to properly assemble, use and re-sell its products. “We really look at training as being one of the key differentiators that we can provide to our distributors,” says Jones, who has worked at Dixon for more than 30 years. “It’s a priority for me.”
Hydraulic flow can be defined as the volume of fluid that flows through a surface area during a specific period of time. Sounds straightforward, right? Well, it turns out there’s more to it than meets the eye. In this post, we will explain the basics and offer several solutions to overcome the challenges you may have faced in your applications.
What makes a specialty contractor special? As opposed to a general contractor, a specialty contractor is someone who concentrates on one particular area of construction, such as plasterwork, site preparation, plumbing, or electrical work. Specialty contractors are often hired by general contractors and project managers for a certain level of expertise on the worksite. Many specialty contractors have received extensive training in their field of practice and must be licensed in the state in which they work. You are likely familiar with a variety of specialty contractors, but here are five that may be new to you:
