ASTM A105 Flanges Manufacturer and Supplier in Thailand

Carbon steel ASTM A105 flanges are constructed using carbon steel or mild steel materials. The material composition typically includes carbon, manganese, phosphorus, sulfur, and iron. SPP Metals & Alloys is a reputable 9001:2015, 14001: 2015, and PED Certified ASTM A105/A105N flanges manufacturer and supplier in Thailand and abroad, specializing in A105/A105N grade carbon steel flanges. These Carbon Steel A105 Reducing Flanges are commonly employed to facilitate fitting and bolt alignment, although certain limitations exist concerning their suitability for pressure, fatigue strength, temperature, service conditions, and more. SA105N flanges are designed to slide over pipes with an internal design slightly larger than the pipe diameter. There are various functional types of flanges available, including ASTM A105 Slip-On Flanges, Carbon Steel Weld Neck Flanges, Carbon Steel Socket Weld Flanges, A105N Carbon Steel Blind Flanges, Carbon Steel Orifice Flanges, A105 Carbon Steel Spectacle Blind Flanges, A105 Screwed/Threaded Flanges, Carbon Steel Reducing Flanges, and ASTM A105N Carbon Steel Ring Type Joint Flanges (RTJ).

Moreover, flanges come in various shapes. Notably, the Carbon Steel A105 Blind Flange is unique, as it seals a connection rather than expanding it. Blind flanges offer several varieties, including butterfly flanges, flat faces, raised faces, and ring-type joint flanges, which are categorized based on their face types. Additionally, the CL.150 A105 Lap Joint Flange ANSI 16.5 is specially designed with a lap joint for enhanced connectivity. These flanges are available in sizes ranging from ½ inches to 48 inches, adhering to standards such as ANSI, ASME, DIN, EN, and other international norms. The ASTM A105N Weld Neck Flanges feature a welded neck that enables better welding and fixture of pipes to the flanges. They are available in various pressure classes, with the ASTM A105 Slip-On Flange being widely used across applications, offering pressure classes from 150 to 1500 and pressure numbers from PN6 to PN64.

What is ASTM A105 Flange?

ASTM A105 standard flanges are commonly crafted from Carbon Steel Flange Material. This particular grade of Carbon Steel Flange Material is highly preferred for the production of forged piping components, including flanges and fittings, primarily tailored for smaller-diameter piping systems. It serves as the foundation for manufacturing Standard Carbon Steel A105 Flanges. The A105 Pipe Flange is versatile, catering to both high and low-temperature pressure systems. However, it’s worth noting that the Carbon Steel Forged Flanges standard imposes a weight restriction, capping forged components at a maximum weight of 4540 Kg. For flanges exceeding this weight limit, ASTM A266 is the preferred choice.
