How to correctly cut your mild steel pipe in projects

Unlike high-carbon steel pipe, mild steel pipe has carbon contents of less than 0.18%, so this type of pipe is easily welded while some types of high-carbon steel pipe, such as stainless steel pipe, which requires special techniques in order to properly weld the material. In some specific cases, we have to cut mild steel pipe in order to cater to an appropriate custom fit for your applications. There are different methods and ways of cutting pipe, and each depends on what types of pipe you are cutting.

As a rule, how to cut galvanized steel pipe generally depending on the metal pipe’s outer diameter as well as its wall thickness. Band saw cutting is a fully automatic process and the most common method for cutting rod, bar, pipe, and tubing. This process is excellent for large-volume cutting. Some band saws can handle large product bundles. Band saw cutting is a viable method for cutting a variety of steel pipe shapes, such as square steel pipe, rectangle pipe, channels, I beams, and extrusions. Despite the many advantages of band saw cutting, it is not an efficient process for cutting thin-walled products. Moreover, band saw cutting produces a burr and does not achieve tight tolerances. In addition, high-precision cold sawing is suitable for cutting smaller-diameter or thin-walled material that requires tight tolerances. A circular cold saw uses a wheel blade and cutting fluid, which usually is applied with a mist lubricator. Cold sawing produces square or perpendicular cuts and minimal or no burrs. This automated cutting method can bundle-cut material with a length tolerance of ±0.004 in. and squareness tolerance of 0.002 in. per diameter inch.

Abrasive sawing is a basic, manual method of cutting-to-length product to the customer’s specification in any alloy. An abrasive saw operates with a circular abrasive blade or resin-composition wheel (either wet or dry) that grinds through the product. While an abrasive saw is easy to use and requires little or no setup time, it cannot provide a square cut or tight tolerances. Because the process uses a cutting or burning action, it is not efficient for thick-walled material. For some steel pipe manufacturers, high-precision cold sawing is suitable for cutting smaller-diameter or thin-walled material that requires tight tolerances. A circular cold saw uses a wheel blade and cutting fluid, which usually is applied with a mist lubricator. Cold sawing produces square or perpendicular cuts and minimal or no burrs.
