Material Selection and Performance Comparison of J-VALVES DBB Flanged Ball Valves under High Temperature and High Pressure ConditionsI. Requirements for Valve Materials under High Temperature and High Pressure ConditionsHigh temperature and high pressure conditions impose extremely stringent require
In oil and gas pipelines, the selection of DBB ball valves is of crucial importance, and full bore and reduced bore designs are two common options. They each have their own characteristics in terms of flow performance and cost. How can we balance these two aspects to make a proper selection? The following will discuss this in detail.
In the industrial field, BALL VALVES are widely used, and different standards have different requirements for their designs. API 6D and ASME B16.34 are two commonly used relevant standards. Understanding the differences in the design of DBB (DOUBLE BLOCK AND BLEED) BALL VALVES under these two standards is crucial for correct selection. The following will provide a detailed comparison and a selection guide.
