SMLSCO offers you Blind Flange made of high quality austenitic stainless steel, duplex steel material, is a flange product with high strength and excellent sealing performance. It is mainly used to temporarily seal off the end of pipelines or equipment for maintenance and testing. Our blind flanges are designed to withstand high temperature and high pressure working environments while meeting diverse sealing requirements. It has a non-porous centre design that provides a robust and effective closure, yet features ease of installation and removal. It is bolted in place with the necessary gaskets to ensure a tight connection between the sealing surfaces.

Production process:
Advantage:
a) Space saving: Compared with other blocking methods, Blind Flange has a more compact design, which can effectively block the pipeline in limited space, and is a space-saving solution.
b) Easy to install and dismantle: As the Blind Flange is bolted in place compared to the pipe cap, it is easier to install when needed and dismantle for future maintenance and overhaul, providing convenience for temporary or long-term pipeline blocking. Strong adaptability: Blind flanges are suitable for high-temperature, high-pressure environments and occasions with very high sealing requirements, and can effectively withstand thermal expansion and contraction in the pipeline system and maintain good sealing performance.
c) Strong structure: As blind flanges are usually made of forgings, this manufacturing method gives them excellent mechanical strength and pressure resistance, ensuring safe and reliable pipeline shut-off.
d) Adaptable: Suitable for high-temperature, high-pressure environments and high sealing requirements, blank flanges can effectively withstand thermal expansion and contraction in pipeline systems and maintain good sealing performance.
e) Standardised production: SMLSCO Blank Flanges are manufactured according to international standards (such as ASME, JIS, DIN, etc.), which ensures consistency of product quality and dimensions, and facilitates worldwide promotion and application.
Package:
As a manufacturer with 17 years of experience in the pipeline industry, SMLSCO has many years of experience in packaging and crating.
For PIPE & TUBE: We use three types of protection: casing caps, packaging in woven bags and wooden crates, and reinforcement with dowels.
For FLANGE: Each flange is supplied with a surface protector and individual bubble bags before being packed in wooden crates. The surface of the flange will not be damaged during transport.
All inspection results and loading process will be documented with photographs to fulfil your traceability requirements.
