Historically, the gas and oil industry has presented production personnel and equipment suppliers with hard and demanding operating situation. For valves, that has translated into an ever-rising need to longer-lasting, tougher, better performing valves.KP-LOK
Demand for gas and oil grew greatly during the industrial revolution and grew even additional to fuel the development of European economies. This demand spurred the need for longer pipelines, deeper wells, and lower production costs, which needed refiners and drillers to pick equipment more carefully. As transportation, production, and processing technology advanced, equipment performance needs became more and more stringent to support rising operational efficiencies. Today, performance expectations are superior than because the range of operations situations has expanded, and the protection of personnel and the atmosphere have been included to the list of needs.
Elevant valves and equipment
Each of these industry segments faces special and diverse atmosphere that, in turn, make extreme operating situations for valves and other flow control components. Because of the high pressures and temperatures, as well as the harshest and remote environments, the kinds of materials and valves for those valves for each segment vary considerably. There are extremely few valve suppliers that could offer a full range of solutions, and most suppliers today specialize in 1 or 2 segments.
This is because of the complexity of needs. For example, in the offshore exploration, upstream segment, and production operations make high conditions, a condition made even harder as the search for gas and oil fields continues into deeper and deeper waters. In these valve strength, applications and performance are critical because of the damage that leakage could lead to the seas and their fragile ecosystems. Standard choices for this segment contain gate valves produced with top alloy materials and, on occasion, ball valves. They are used for a big range of reasons including corrosion to resistance and damage caused by constant exposure to raw sea water. Further, these valves provide low-depth sensitivity and have confirmed over time to do well in this remote environment and high pressure.
Specific valves for the industry
Refinery segments that use valves contain vacuum distillation, atmospheric distillation, catalytic reforming, hydrotreating, alkylation, fluidized catalytic cracking, double block and bleed valve, delayed coking, vibreaking, sulfur recovery, gas plants and cube treating. The perfect kinds of valves for these applications change widely, but, in general, they contain multi-turn valves, quarter turn valves, HF alkylation valves, and flow reversal protection valves, to title a few.
Multi-turn valves, such as globe valves and bolted bonnet gate, are generally offered in materials developed to accommodate a big range of flow media. These valves spec a body cast with straight-through ports to decrease erosion, turbulence, and force drop. Further, these valves can be outfitted with seat rings seal-welded to get rid of possible leak paths behind the rings. Specifically developed stuff are used in more higher or erosive temperature services.
