Here’s How a Pressure Gauge Works

Pressure gauges are used in several industrial applications such as cooling, mining and oil drilling to monitor and measure the fluid pressure of a hydraulic system. They help ensure that the crew can monitor pressure changes to prevent leaks, equipment damages, or explosions. Here’s how the mechanism of a pressure gauge works.

The Mechanism Of A Pressure Gauge

There’re many types of pressure gauges, but the most common is the bourdon tube gauge. The bourdon tube includes a semicircular and flat metal tube where one end is fixed while the other end is attached to a lever mechanism. As the pressure increases, the force of the fluid straightens the curved tube and pulls the lever. Bourdon tubes convert the force from the pressure into mechanical energy and move the needle on the dial to display the measure of fluid pressure.

How To Work With Standpipe Pressure Gauges UMG

Standpipe pressure gauge is a bourdon-tube used to monitor and regulate mud pressure for extraction in drilling applications. Standpipe pressure is the total pressure loss of annulus pressure loss, dill string pressure loss, bottom home assembly pressure loss and pressure loss across the drill bit. Low standpipe pressure will increase the chances of the down drill string break down and high standpipe pressure will increase mud density. Properly monitoring and regulating standpipe pressure with a standpipe pressure gauge UMG prevents downhole complications. However, mechanical pressure gauges are sensitive to high vibration and pulsations, and thus an electronic gauge is ideal in such situations.

How To Work With Electronic Gauges

Electronic gauges are a recent iteration compared to the traditional analog gauges. The mechanical energy in the electronic gauge is converted to electrical energy to display a unit of measure on the OLED display of the dial. It can display necessary information such as pump strokes and total strokes on a backlight display, allowing it to be used at night. Electronic coil tubing gauges provide extra reliability as electronics eliminate high-pressure lines.

How to Avoid OSHA Violations at Your Drilling Rig

Image
  The health and safety of workers in the oil and gas mining industry are major concerns. Exposure to hazards, extreme work environments, and accidents while operating heavy machinery means that oil/gas industry employees are at a higher risk of injuries and fatalities. As a result, the Occupational Safety and Health Administration ( OSHA ) has outlined certain precautions that help prevent accidents and keep your employees and worksite safe. Significant focus has been put on inspecting oilfield worksites, so you want to be prepared for any unexpected visits at your facility at all times. Staying prepared means that not only do you get to avoid fines and citations , but you also keep your workers protected. Let’s take a look at the top three violations on OSHA’s list, as well as the steps you can take to prevent them. 1. Inadequate Fall Prevention According to the National Safety Council, falls are among the most common hazards in the workplace, leading to approximately 50,000 severe i

Most Common Oilfield Instrumentation Issues

Image
Oilfield instrumentation  is a system of measuring, recording, and analyzing parameters such as temperature, pressure, and flow rate. It’s used to monitor the production of petroleum and natural gas wells. Here are five common oilfield instrumentation issues that oilfield operators should know about. Equipment Failure Equipment can either fail mechanically or electrically. The most common failures are due to power surges or lightning strikes. Electrical failure is one of the most common causes of oilfield instrumentation issues. They are caused by improper grounding or insulation issues with wiring in the wellhead. Mechanical failures  are usually due to wear and tear on moving parts caused by high-temperature environments or corrosion from corrosive chemicals in the wellhead. Lack of Communication Between the Wellhead and the Surface Any oilfield or gas field instrumentation is at risk of malfunctioning if the communication between the wellhead and surface is faulty. One issue that ca

Types of Weight Indicator Systems and Their Uses

Image
Weight indicator systems  are commonly used for weight or load indication during oil or drilling processes. It is a valuable instrument that can help you detect and provide accurate readings on the measuring scale. There are different types of weight indicator systems that you can use for minor processes or heavy-duty drilling operations. Contact Instruments  has the best quality and user-friendly weight indicator system that not only offers accurate reading but an exceptional user experience. What are some common types of weight indicator systems? Let's find out. Anchor Type Weight Indicators Anchor weight type weight indicators  offer a quick and efficient indication of hook load and provide a practical drilling experience. Some of its features include: ·  They can be configured in a custom manner with several other tools like pressure gauges, torque gauge, and pump stroke meter. ·  They offers load tolerance of 30,000 pounds to 200,000 pounds. ·  It also consists of dampers that
