Hydrotests (otherwise known as Hydrostatic or Pneumatic Tests) are used to measure the rate of expansion of the unit (pipeline or pressurized vessel such as tank, etc…) to determine if they can safely hold the amount of pressure the vessel is rated for. It ensures that the weld joints and flanges are fitted properly and confirms that the material used has the required strength to sustain the specified pressure. They are often used: 𝑭𝒐𝒓 𝑵𝒆𝒘 𝑷𝒊𝒑𝒆𝒍𝒊𝒏𝒆 𝑪𝒐𝒏𝒔𝒕𝒓𝒖𝒄𝒕𝒊𝒐𝒏: - to test the structural integrity of a pipeline or segment of pipeline (or pressurized vessel such as a tank) following construction (or installation in the case of a tank) before commissioning to verify the safety and readiness for service.

The below photo is of a bridle we're currently building for one of our large refineries. This bridle has 3 level gauges, multiple process connections and multiple level switch connections. We're also providing the steam tracing and insulation jackets for this project. This is a great example of one of the more complex level bridles we're capable of producing for you. All you have to do is ask us to come take a look at your application and we'll walk the job down, take all dimensions, get all the flange and fitting connection sizes/schedules, get a copy of your paint system and pipe specification, get a PO and then provide you with a fully and complete bridle/level package that you can bolt up in place of the old. We are able to include all coating, MTR's, Hydro and Certs, Welding procedures, ASME stamps where required, NDE, Engineered drawings, illuminators, steam tracing, insulation jackets and more.

Friction welding of drill pipe is an advanced welding technology used in the manufacture of drilling equipment in the oil and gas industry. It is mainly used to connect pipe sections of drill pipe to form a continuous drill pipe column. Friction welding (FW) is a solid-state welding method that does not involve filler materials or shielding gases. The friction heat generated by the rotational motion makes the two metal surfaces reach a plastic state, and then welds under pressure. The drill pipe after welding is subjected to necessary mechanical processing, such as turning the end face, to ensure dimensional accuracy and surface finish. Non-destructive testing (NDT), ultrasonic testing (UT) or radiographic testing (RT) are also required to verify the welding quality. The application of friction welding technology in drill pipe manufacturing can improve welding efficiency, reduce energy consumption, and the welded joint has high strength and good reliability. It is particularly suitable for drill pipes that need to withstand high pressure, high temperature and complex underground conditions. In addition, since the metal does not melt during the welding process, the possibility of welding defects is reduced, and the overall performance and service life of the drill pipe are improved. #drillpipe #pipe #drawworks #BOP #topdrive #TDS #usedrig #drillingrig #mudpump #pump #workoverrig #750hp #industrialpower #bop #Reliability #PrecisionPerformance #OilDrilling #QualityProducts #OilandGas #Engineering #workover #workoverrig #oilindustry #oilfield #drilling #oildrilling #energyindependence #oil

Understanding Long Seam Weld Orientation 1. Long Seam Weld: This is the weld that runs along the length of a pipe, usually created during the manufacturing process. When two pipes are welded together end-to-end, each pipe has its own long seam weld. 2. Orientation of the Weld: When connecting two pipes, you can choose where the long seam weld of the second pipe aligns relative to the long seam weld of the first pipe. The recommendation is to position the long seam weld of the second pipe between 90 to 180 degrees from the weld of the first pipe. Why 90 to 180 Degrees? - Crack Propagation: Cracks in welded structures often follow the path of least resistance. If the weld seams of adjacent pipes are aligned (0 degrees), a crack that starts at the weld seam of one pipe can easily continue into the seam of the next pipe. - Changing Direction: By rotating the seam by 90 to 180 degrees, any potential crack would have to change direction to continue propagating from one pipe to the next. This change in direction requires more energy and makes it more difficult for the crack to continue, thereby slowing or stopping its progression. Benefits of This Approach 1. Increased Durability: By restricting the propagation of cracks, the overall durability of the pipeline is improved. This reduces the likelihood of sudden and catastrophic failures. 2. Improved Safety: Cracks that are stopped or slowed are less likely to lead to complete pipe failure, improving the safety of the structure. 3. Maintenance and Inspection: Knowing that weld seams are staggered helps maintenance and inspection teams focus on specific areas where stresses might accumulate, making it easier to monitor the integrity of the pipeline. #welding #pipe #oilandgas #mechanical #engineering #oil #field #oman

Press fit connections are becoming increasingly popular in the piping industry with one of its most significant advantages over welding being its speed and cost-effectiveness. Press fit is more than 10 times faster than traditional welding methods, translating into reduced labour costs and increased productivity. Press fit does not require hot work permits, making installation easier and more economical. This means that press fit connections can be installed quickly without shutting down an entire system for an extended period. Another advantage of press fit connections is their ease of installation. Since no specialist skills are required to install press fit connections, it can be done by a wider range of technicians without the need to hire expert welders. This significantly reduces the time and resources required to install piping systems. Moreover, press fit connections eliminate the need for extensive preparation work that is necessary for welding. This includes cleaning, grinding, and preheating, which can add to the total cost and time of a project. To speak to one of our experts about using press fit in your project.

𝗛𝗲𝗮𝘁 𝗔𝗳𝗳𝗲𝗰𝘁𝗲𝗱 𝗭𝗼𝗻𝗲 𝗖𝗿𝗮𝗰𝗸 The heat affected zone (hashtag #HAZ) of a weld is not limited to the weld itself but to the immediate area of parent material surrounding the weld. A HAZ crack can originate at the toes of the weld or a few millimeters from the weld altogether.
