Introducing the exquisite Bl Blind Flange Blind Plate, a marvel of engineering by Dingxiang Jinyu Forging Co., Ltd. This solid circular masterpiece boasts strategically placed bolt holes, offering unparalleled versatility with multiple sealing surface options: flat, convex, male and female, tongue and groove, and ring joint surfaces. Crafted from premium materials like carbon steel, stainless steel, alloy steel, copper, and aluminum, this flange plate excels in sealing, isolating, and cutting off applications, ensuring flawless performance by preventing leaks or overflow in your pipeline systems. Perfect for equipment testing, pressure assessments, and more, it is designed for easy disassembly, seamless connectivity, and remarkable pressure endurance. Its high mechanical strength, robust sealing capabilities, and exceptional chemical stability make it indispensable in industries like petroleum, chemical engineering, shipbuilding, pharmaceuticals, metallurgy, machinery, and food production.
| Structural Length | For blind flanges with different connection forms, their structural lengths vary. For example, the structural length of a butt-welding blind flange generally refers to the distance from the sealing surface of the flange to the back of the flange. This parameter is related to factors such as pipeline layout and installation space. Common dimensions range from dozens of millimeters to several hundred millimeters, and the specific values change according to the nominal diameter and pressure class. |
| Flange Type | Common types include flat welding blind flanges for plate type, slip-on welding blind flanges with a neck, butt-welding blind flanges with a neck, socket welding blind flanges, threaded blind flanges, etc. Different types of flanges are suitable for different working conditions and pipeline connection requirements. For instance, butt-welding blind flanges with a neck are suitable for pipeline systems with high temperature, high pressure, and strict sealing requirements, while flat welding blind flanges for plate type are commonly used for low-pressure and non-critical pipeline connections. |
| Weight | The weight of a blind flange is closely related to factors such as material, size, and thickness. Generally speaking, the weight of a carbon steel blind flange with DN100 and PN16 may be around 5kg - 10kg. For a stainless steel blind flange of the same specification, due to the relatively high density of the stainless steel material, the weight may be around 6kg - 12kg. The weight has an important impact on operations such as hoisting during transportation and installation. |
| Applicable Temperature Range | The applicable temperature ranges of blind flanges made of different materials are different. Carbon steel blind flanges are generally suitable for a temperature range of -20°C - 450°C; the applicable temperature range of 304 stainless steel blind flanges is generally around -196°C - 800°C; and the applicable temperature range of 316 stainless steel blind flanges is approximately -196°C - 850°C. The actual operating temperature also needs to take into account the influence of factors such as the characteristics of the medium and pressure. |
| Hardness | It is usually expressed by Brinell hardness (HB) or Rockwell hardness (HRC). For example, the Brinell hardness of a general carbon steel blind flange may be between 120HB - 200HB. For a stainless steel blind flange after processes such as heat treatment, its Rockwell hardness may reach around HRC25 - HRC35. The hardness affects the wear resistance and deformation resistance of the flange. |
