This sequence is common to all flanges, regardless of the material. It is essential to follow this sequence to avoid any damage to the flange or piping system. The tightening sequence should be done in a star pattern, tightening one bolt, then moving to the next one in a diagonal direction. This helps to ensure even tightening and prevents any uneven stress on the flange. By following the recommended bolt tightening sequence, users can ensure a secure and reliable connection. Proper tightening is critical for safety and efficiency in various industrial applications.
Hydraulic Tensioning for Larger Bolt Diameters
Hydraulic tensioning is a method used for larger bolt diameters to achieve precise and consistent tightening. According to the flange bolt torque chart pdf, for bolt diameters greater than 1.25, hydraulic tensioning is recommended to achieve more accurate and efficient tightening. This method uses hydraulic pressure to stretch the bolt, ensuring a precise and controlled amount of tension. The use of hydraulic tensioning for larger bolt diameters helps to reduce the risk of overtightening or under-tightening, which can lead to flange damage or leakage. By using hydraulic tensioning, users can ensure a reliable and secure connection, even for larger and more complex flange assemblies. This method is particularly useful in industries where large flanges are commonly used, such as in oil and gas, or power generation. Proper training and equipment are necessary for safe and effective hydraulic tensioning.
