What is a flat weld flange?
Plate flat weld flanges are suitable for connecting steel pipes with a nominal pressure not exceeding 2.5MPa. The sealing surface of a flat weld flange can be made into three types: full plane, concave and convex, and tongue and groove. The neck height of a necked flat weld flange is relatively low, which improves the rigidity and bearing capacity of the flange. Compared with butt weld flanges, the welding workload is large, the consumption of welding rods is high, and it cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations, but it is more convenient to install on site, and the process of beating and rubbing the weld can be omitted, so it is more popular.
Application of ASTM A105 slip-on flange
ASTM A105 slip-on flange has excellent physical and mechanical properties and is widely used in pipeline systems in industries such as petroleum, chemical, electric power, and construction. In pipeline connection, two slip-on flanges are generally sealed by bolts and gaskets, and one end of the pipeline is welded to the neck of the slip-on flange to achieve the function of connecting the pipeline.
ASTM A105 slip-on flange is suitable for pipeline systems with relatively low pressure levels and no serious pressure fluctuations, vibrations, and shocks. Slip-on flanges not only save space and reduce weight, but more importantly, ensure that there will be no leakage at the joint and have good sealing performance. And it is cheaper than butt-weld flanges, so it has been widely used.
Product advantages of ASTM A105 slip-on flange
1. Wide size coverage: The size range of ASTM A105 butt-weld flanges covers 1/2 inch to 24 inches, and in some cases, its size range may even extend to large flanges from 26 inches to 60 inches. This wide size range meets the needs of different fields and equipment of different sizes.
2. Complete pressure levels: ASTM A105 butt welding flange has a complete range of pressure levels from 150 pounds to 2500 pounds. Whether in low-pressure
pipelines or high-pressure systems, suitable pressure levels can be found to ensure safe and reliable operation.
3. Strict quality control: ASTM A105 butt welding flanges implement strict quality control measures during the production process. From the storage of raw materials to the delivery of products, every link is strictly inspected and tested to ensure that each product meets or even exceeds customer requirements.
4. High cost performance: Compared with similar products, ASTM A105 butt welding flanges have a higher cost performance. Its high-quality materials, exquisite craftsmanship and reliable performance enable it to maintain a reasonable price level while meeting strict quality requirements, saving customers procurement costs.
ASTM A105 butt welding flanges have become an indispensable and important component in the industrial field due to their excellent performance and wide application. Whether in traditional industrial fields or emerging industries, it will play a more important role in future development.
