Understand the pipe end bevels and its processing methods

In the world of piping, precision is paramount, and one crucial element that ensures the highest quality welds is the preparation of pipe end bevels. These bevels come in various forms, each tailored to specific welding requirements. Let’s delve into the world of pipe end bevels and their significance in welding excellence.

Understanding pipe end bevels

I-Type Bevel: For pipes with a wall thickness below 3.5mm, the I-type bevel is the go-to choice. Its streamlined design facilitates seamless welding operations, ensuring a secure and reliable connection.

V-Type Bevel: Medium to low-pressure steel pipes find their ideal match in the V-type bevel. Characterized by an angle of 60° to 70°, this bevel boasts a slight root face and a thickness of around 2mm. It’s the solution for achieving robust welds.

U-Type Bevel: When dealing with high-pressure steel pipes featuring a wall thickness ranging from 20mm to 60mm, the U-type bevel takes center stage. Its design includes a slight root face, approximately 2mm thick, ensuring strength and durability in high-stress applications.

Processing methods for bevels

Now, let’s explore the methods used to craft these precision bevels:

Low-pressure carbon steel pipes (Nominal Diameter ≤ 50mm): Hand-held grinding wheels are wielded for beveling purposes. For diameters exceeding 50mm, oxy-acetylene gas cutting comes into play. Following the cut, a hand-held grinding wheel is employed to eliminate any oxidation layers, leaving a smooth, ready-to-weld surface.

Medium-pressure carbon steel pipes, stainless acid-resistant steel pipes, and more: In the realm of medium-pressure carbon steel pipes, stainless acid-resistant steel pipes, low-alloy steel pipes, and various high-pressure steel pipes, precision is achieved through lathe processing. This ensures that the bevels meet exacting standards for welding applications.

Non-ferrous metal pipes: When it comes to non-ferrous metals, manual filing is the preferred method for crafting impeccable bevels.

In the intricate world of piping, where quality and precision are non-negotiable, pipe end bevels stand as a testament to the commitment to excellence. These bevels, carefully tailored to the specifics of each project, ensure welds that are not just strong but also dependable. They’re the cornerstone of seamless connections, facilitating the flow of liquids and gases in a diverse range of applications.
