Singapore customer ordered API 6BX RTJ ASTM A694 F65 blind flanges
We are delighted to announce a new order from our Singaporean client for the API 6BX RTJ ASTM A694 F65 blind flanges. This product is specifically engineered to meet the rigorous demands of high-pressure environments in the oil and gas industry. In this article, we will delve into the details of the API 6BX standard, the significance of the RTJ sealing surface, and the specific chemical and mechanical properties of the ASTM A694 F65 material.
The API 6BX RTJ ASTM A694 F65 blind flanges are manufactured according to the API 6BX standard, a part of the API 6A specification that governs wellhead and Christmas tree equipment. Flanges under this standard are designed to withstand extremely high pressures, making them suitable for critical applications where reliability is essential.

Understanding the RTJ Sealing Surface
The API 6BX RTJ ASTM A694 F65 blind flanges are equipped with a ring type joint (RTJ) sealing surface. RTJ is a specialized metal-to-metal sealing mechanism commonly used in high-pressure and high-temperature applications. The RTJ flange features a precisely machined groove that houses a metal ring gasket. When bolted together, the flange compresses the gasket into the groove, creating a tight, leak-proof seal. This design is particularly effective in preventing leaks under extreme conditions, making the API 6BX RTJ ASTM A694 F65 blind flange an ideal choice for demanding environments.
Chemical Composition of ASTM A694 F65
The API 6BX RTJ ASTM A694 F65 blind flanges are made from ASTM A694 F65 material, a high-strength, low-alloy steel designed for high-pressure transmission applications. The chemical composition of ASTM A694 F65 typically includes:
Carbon (C): 0.10 – 0.25%，Manganese (Mn): 1.15 – 1.65%，Phosphorus (P): Max 0.025%，Sulfur (S): Max 0.025%，Silicon (Si): 0.15 – 0.35%，Chromium (Cr): 0.25 – 0.45%，Nickel (Ni): 0.25 – 0.45%
Molybdenum (Mo): 0.08 – 0.15%，Vanadium (V): 0.03 – 0.08%
This precise chemical composition gives the API 6BX RTJ ASTM A694 F65 blind flange its excellent strength and toughness, making it capable of withstanding the harsh conditions of high-pressure environments.
Mechanical Properties of ASTM A694 F65
The mechanical properties of the ASTM A694 F65 material used in the API 6BX RTJ ASTM A694 F65 blind flanges are equally impressive, ensuring its durability and performance. These properties include:
Tensile Strength: 485 MPa (70,300 psi) minimum，Yield Strength: 450 MPa (65,300 psi) minimum，Elongation: 22% minimum，Reduction of Area: 35% minimum，Impact Toughness: Charpy V-notch test at -46°C (-50°F) typically yields 27 J (20 ft-lb) minimum
These mechanical properties enable the API 6BX RTJ ASTM A694 F65 blind flanges to maintain structural integrity and resist failure even in the most challenging conditions, such as in offshore drilling or deep-sea pipeline systems.
The API 6BX RTJ ASTM A694 F65 blind flanges ordered by our Singaporean client exemplifies our commitment to providing top-quality products that meet stringent industry standards. With its robust RTJ sealing surface and the superior chemical and mechanical properties of ASTM A694 F65 material, this flange is designed to perform reliably in high-pressure environments, ensuring the safety and success of critical operations.
We look forward to continuing to support our clients worldwide with high-quality piping components like the API 6BX RTJ ASTM A694 F65 blind flanges, contributing to the success of their projects.
