Khaleed Stainless is a reputable manufacturer and supplier based in Riyadh, Saudi Arabia, specializing in high-quality Stainless Steel Spectacle Blind Flanges. These flanges are expertly designed to ensure reliable flow control and safety in piping systems. Shaped like a pair of glasses, they feature a solid end (the blank) and an open end (the spacer), linked by a small metal section. Crafted from top-grade stainless steel, these Spectacle Blind Flanges are built to withstand corrosion, high pressure, and extreme temperatures. At Khaleed Stainless, we prioritize precision engineering and compliance with global standards, making our flanges perfect for the oil & gas, petrochemical, power, and process industries.
Stainless Steel Spectacle Blind Flanges are generally made from grades 304, 304L, 316, 316L, and 321. These grades contain chromium (18–20%), nickel (8–12%), and molybdenum (2–3%) in some cases to boost their resistance to corrosion and pitting. They showcase impressive tensile strength ranging from 515 to 620 MPa and yield strength between 205 and 290 MPa, along with excellent toughness even in high-pressure and high-temperature situations. Their mechanical stability allows for easy switching between flow and shut-off. With their high hardness, durability, and resistance to scaling, these flanges excel in demanding pipeline environments.

Stainless Steel Spectacle Blind Flanges typically do not require corrosion protection coatings due to their inherent corrosion resistance. However, in highly corrosive environments, additional coatings may be applied for enhanced protection.
Stainless Steel Spectacle Blind Flanges are commonly utilized in industries that require regular inspection, maintenance, or isolation of pipelines. In oil & gas and petrochemical facilities, they play a crucial role in regulating or blocking fluid flow in essential process lines. Power generation plants rely on them for the safe operation of boilers and condensers. The chemical and marine sectors depend on these flanges for their corrosion-resistant pipeline systems. They’re also found in water treatment plants and refineries. Their ability to quickly and securely switch between open and closed flow makes them vital in today’s process industries.
