Precise pipeline isolation and standardized component identification are critical for stable operation of petrochemical and energy piping systems in Singapore. Haihao Group has completed professional fabrication and delivery of custom A350 LF2 spectacle blind flanges, tailored to meet local industrial project’s strict low-temperature material and standardized marking requirements.

ASME B16.48 A350 LF2 CL1 spectacle blind flange, 6 inch Class 600 FFTBE flat face pipe blind with NACE standard color bands shipped to Singapore

Full Product Specification

This shipment features 6-inch Class 600 spectacle blind flanges manufactured in full compliance with ASME B16.48 industrial standards. Adopting premium A350 Gr LF2 CL1 low-temperature carbon steel, the A350 LF2 spectacle blind delivers excellent toughness and structural stability under variable temperature working conditions, perfectly adapting to complex industrial pipeline switching and isolation scenarios in Singapore’s tropical industrial environment.

Different from ordinary carbon steel spectacle blinds, this batch of A350 LF2 spectacle blind adopts FFTBE flat face finish, ensuring flat and seamless fitting with matching flanges for reliable pipeline sealing performance under Class 600 high-pressure operating conditions. The integral forging process eliminates internal structural defects, guaranteeing long-term pressure resistance and isolation safety of pipeline systems.

Strict standardized surface treatment and color marking are implemented for every A350 LF2 spectacle blind. The flange surface is uniformly coated with anti-rust black paint for enhanced corrosion resistance. Meanwhile, professional NACE standard color band identification is applied with green (RAL 6021) and white (RAL 9010) dual color strips, enabling quick and accurate component identification for on-site construction and daily maintenance.

Each finished flange undergoes strict dimensional inspection and surface quality verification before shipment. The standardized NACE color marking system complies with international industrial piping identification norms, effectively improving on-site construction efficiency and avoiding component misinstallation. The complete product configuration fully meets the refined construction standards of high-end industrial projects in Singapore.

Haihao Group specializes in standardized and customized low-temperature pipeline isolation components. We supply high-quality A350 LF2 spectacle blind flanges with full standard compliance, customized surface painting and standard color marking solutions, supporting one-stop procurement for various high-pressure industrial piping projects in Southeast Asia.
