Production Cycles of Seamless Carbon Steel Pipes The production cycle of seamless carbon steel pipes largely depends on the manufacturing method used. There are several common techniques for producing these pipes, including hot rolling, cold rolling, and cold drawing. If you're wondering how long it typically takes to produce a seamless carbon steel pipe, read on to find out more. 1. Hot Rolling 2. Cold Rolling 3.

Hot rolling involves heating steel billets above 1000°C and then subjecting them to rough rolling and finishing rolling processes. This method is ideal for producing carbon steel and low-alloy steel pipes, especially those with larger diameters. Most manufacturers have minimum order quantity (MOQ) requirements, and for hot-rolled seamless pipes, the MOQ tends to be relatively high. When demand is lower, production can be scheduled based on the mill’s overall production plan, which may include multiple specifications. For large-diameter hot-rolled pipes, small orders of tens of tons usually follow the mill's schedule without being processed separately. While the production speed is fast, small batch orders typically take more than 20 days to complete, depending on the production plan.
Cold rolling is performed at room temperature using a cold rolling mill, making it suitable for producing small-diameter seamless steel pipes. The finished product has a bright surface with minimal dimensional errors. This process is flexible and can handle both large and small batches. However, the processing speed is slower compared to hot rolling, and the typical production cycle ranges from 10 to 15 days, depending on the manufacturer's schedule.
Cold drawing is a method used to reduce the diameter of seamless carbon steel pipes, mainly for producing smaller diameter pipes. It offers high flexibility in terms of production quantity and has a low minimum order quantity, allowing both small and large orders to be fulfilled. The outer diameter error is minimal, and the surface finish is smooth, making it ideal for products that require tight tolerances on the outer diameter. However, the inner diameter tolerance is not as precise. If both inner and outer diameters need to meet strict requirements, an inner mandrel can be used during the cold drawing process. This method is fast, with a typical production cycle of 7 to 10 days, depending on the schedule.
