In oil and gas pipelines, DBB ball valves are like "gatekeepers" controlling the flow of media. Especially within the wide pressure range from 150LB to 2500LB, whether they can stably withstand pressure and comply with international standards is directly related to the safety of the pipelines. Today, let's talk about how to conduct a comprehensive "check-up" for ball valves through pressure resistance testing and verification against the ASME B16.34 standard.

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 high-pressure pipeline systems, DBB ball valves are widely used, and their anti-blowout valve stem and self-relieving structures play a crucial role in ensuring the overall safety performance. The following will analyze in detail how these two structures enhance the safety performance of DBB ball valves in high-pressure pipelines.

Recently, J-VALVES received good news. The DBB ball valves (Double Block and Bleed Ball Valves) supplied for a key project have successfully passed the customer's acceptance. During this acceptance, the customer formed a professional team to conduct a comprehensive and strict inspection of the produ

Understanding Stainless Steel 304Properties of Stainless Steel 304Stainless steel 304 is a versatile and widely used austenitic stainless steel known for its excellent corrosion resistance, formability, and toughness. Key properties include:• Corrosion Resistance: Stainless steel 304 is highly resis

DBB ball valves play a crucial role in industrial pipeline systems. With its unique double block and bleed design, it can ensure that when the valve is closed, the medium in the pipeline is effectively blocked, and at the same time, the residual medium in the valve chamber can be discharged, greatly

DBB (Double Block and Bleed) ball valves and DIB (Double Isolation and Bleed) ball valves are two common types of industrial ball valves. They have significant differences in sealing principles, seat structures, and pressure relief mechanisms.

Selection Key Points(I) Working Pressure and TemperatureSelect appropriate pressure and temperature ratings according to the working conditions. The pressure ratings of DBB ball valves usually cover 150, 300, 600, etc., with a nominal pressure range of 16-100, and an applicable temperature range fro

Application scenarios in petroleum refiningThe petroleum refining process involves high temperatures, high pressures and corrosive media, which places extremely high demands on the performance of valves. The DBB ball valve is suitable for a variety of media, including aviation kerosene, light oil, n

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.

In the global industrial market, it is crucial for DBB BALL VALVES to obtain CE certification and API 6D certification if they want to enter both the European and North American markets simultaneously. So, what are the key points of the compliance design to meet these two certifications? The following will introduce them in detail.
