ASME B16.5 10″ weld neck flange ASTM A694 GR. F65 NACE MR0175 produced by Haihao Group for Singapore customers

Haihao Group is proud to fulfill another critical order from a valued Singapore client. This time, the order included a 10″ x 10″ weld neck flange designed and manufactured to meet the stringent standards of ASME B16.5 and NACE MR0175. Below are the key product specifications:

• Size: 10″ x 10″
• Rating: 600#
• Type: Weld Neck Flange (WN), Raised Face (RF)
• Material: ASTM A694 GR. F65
• Pressure Class: STD
• Standards: ASME B16.5, NACE MR0175

Product Overview

The weld neck flange (WN) is a high-performance flange type designed for critical applications requiring exceptional strength and reliability. Its long tapered neck enhances its structural integrity by distributing stress across the pipe connection, making it ideal for high-pressure and high-temperature environments. The raised face (RF) design provides a secure sealing surface, ensuring leak-proof connections in demanding applications.

Material Excellence: ASTM A694 GR. F65

This flange is made from ASTM A694 GR. F65, a high-yield carbon steel material commonly used in high-pressure piping systems. With excellent tensile strength and toughness, this grade is particularly suited for harsh environments and high-pressure applications.

To meet the requirements of NACE MR0175, the flange is resistant to sulfide stress cracking and hydrogen-induced cracking, making it suitable for sour gas environments. This ensures the flange’s durability and reliability in oil and gas operations where hydrogen sulfide (H₂S) is present.

Standards and Specifications

Complying with ASME B16.5, this flange guarantees adherence to dimensional accuracy, pressure rating, and manufacturing standards required for industrial piping systems. The 600# pressure rating and STD wall thickness ensure excellent performance under challenging operating conditions.
