Haihao Group delivers tailored solutions to domestic shipyard

Haihao Group takes pride in its ability to deliver a wide range of flange solutions tailored to the diverse needs of our customers. Recently, a domestic shipyard placed an order for a batch of blind flanges, encompassing various specifications and standards.

ASME B16.47 Series A CL150 RF ASTM A105N DN650-DN800:

The ASME B16.47 Series A flange standard is designed for large-diameter, high-pressure applications. This standard features a larger diameter flange and a higher pressure rating compared to its counterpart, ASME B16.5. The Class 150 rating indicates the pressure-temperature rating of the flange, while the Raised Face (RF) design ensures a tight and secure seal. Made from ASTM A105N material, these blind flanges are suitable for use in critical applications demanding reliability and durability.

ANSI ASME B16.5 A350 LF2 RF RTJ blind flanges

ASME B16.5 CL150 RF ASTM A105N DN350-DN600:

ASME B16.5 is a widely recognized standard for pipe flanges and flanged fittings. This standard covers a broad range of sizes and pressure ratings, making it suitable for various industrial applications. The Class 150 designation signifies the pressure-temperature rating of the flange, while the Raised Face (RF) configuration ensures effective sealing. Constructed from ASTM A105N material, these blind flanges offer excellent performance and reliability in moderate-pressure environments.

JIS B2220 FF ASTM A105N DN350-DN750:

JIS B2220 is a Japanese Industrial Standard that specifies the dimensions, tolerances, and materials for steel pipe flanges. Unlike ASME standards, JIS flanges are typically flat-faced (FF) rather than raised face. This standard is widely used in Japan and other Asian countries, offering compatibility with equipment and components designed to JIS specifications. The blind flanges manufactured by Haihao Group under this standard, crafted from ASTM A105N material, meet the stringent requirements of our customers in the domestic shipyard industry.

Haihao Group is committed to providing tailored flange solutions that meet the specific needs of our customers. Whether it’s ASME B16.47, ASME B16.5, or JIS B2220 standards, we ensure that our blind flanges are manufactured to the highest quality standards and comply with relevant specifications. With our expertise and dedication to customer satisfaction, Haihao Group remains a trusted partner for the supply of flange products in the maritime industry.
