Hot rolling involves heating steel billets to over 1000°C before 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. There is usually a minimum order quantity requirement, and the threshold for hot-rolled seamless pipes tends to be relatively high. When demand is low, manufacturers often combine orders based on the steel mill's production schedule. For large-diameter hot-rolled pipes, small orders of tens of tons typically follow the mill’s planned production, and separate schedules are rarely made. While the production speed is fast, small batch orders may take more than 20 days, depending on the production plan.
Cold rolling is performed at room temperature using a cold rolling mill to create smaller diameter seamless steel pipes. This process results in a bright surface finish with minimal dimensional errors. It is suitable for both large and small batch production. However, the processing speed is slower compared to other methods, and the typical production cycle ranges from 10 to 15 days, depending on the schedule.
Cold drawing is a technique used to reduce the diameter of carbon steel pipes, primarily for small-diameter applications. It offers flexible production quantities and lower minimum order requirements, making it suitable for both large and small orders. The outer diameter has a small error, and the surface is smooth, which makes it ideal for products with strict outer diameter specifications. However, the inner diameter may have a larger error. To achieve tighter tolerances on both inner and outer diameters, an inner mandrel can be used during the cold drawing process. This method is fast, with a general production cycle of 7 to 10 days, depending on the production schedule.
