What is the design principle behind the RTJ in an ring joint face flange?

The design principle behind the RTJ ring gasket in a ring joint face flange is to create a strong and reliable seal in high pressure conditions. The RTJ flange has a groove and metal ring compressed between the flange faces during installation. This creates a tight seal which ensures excellent pressure containment and resistance to leakage. Thus, the RTJ gasket types are suitable for demanding applications in oil & gas industries.

How do you choose the right bolts sizes for a RTJ WN flange?

To choose the right bolt sizes for an RTJ WN flange, the flange size, pressure rating, and material thickness are considered. Consult industry standards that provide recommended bolt sizes based on the flange dimensions.

What are the 7 common complaints of the buyers about RTJ face flange?

RTJ face flange has difficulties in achieving proper alignment during installation.
Challenges in achieving a leak-free seal due to improper gasket installation or selection.
Issues with flange face damage or corrosion.
Inconsistent quality of flanges received from suppliers.
Lack of proper documentation or certification.
Difficulty in finding compatible gaskets.
Limited availability of specific sizes or materials.

You can contact Schulzmaan to overcome these issues and get quality flange at your doorstep.

What is the benefits of gaskets in ring type joint (RTJ) flange connections?

Gaskets offer a reliable seal to prevent leakage and maintain the integrity of the joint.
They also help to compensate for surface imperfections and ensure a secure ring type joint flange connection.
They also provide resistance to high temperatures, pressures and corrosive environments.
