ASME SA815 / ASTM A815 F304 / 304L Flat Face Blind Flange
Blind Flange:
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.

Blind Flange Testing:
At SMLSCO, we subject every blind flange to rigorous testing to ensure the highest standards of performance and safety. In addition, through material composition analysis, mechanical property testing, and a variety of non-destructive tests (including ultrasonic, X-ray, magnetic particle, and penetration flaw inspection), we comprehensively ensure that each blind flange is strong, reliable, and durable. Finally, through rigorous pressure and sealing surface inspections, we ensure that every blind flange provides superior closure in high-pressure environments. What we offer you is not only a product, but also a guarantee of quality and peace of mind.
