The most common connection method for large-diameter spiral steel pipes is welding. However, threaded connections, flange connections, socket connections, and grooved connections are also frequently used in some projects.First, Welding and Flange Connections for Large-Diameter Spiral Steel Pipes.Wel
READ MOREPlastic-coated steel pipes, also known as plastic-coated pipes, steel-plastic composite pipes, or plastic-coated composite steel pipes, are steel-plastic composite pipes with a steel pipe base. A layer of plastic anti-corrosion coating is fused to the inner surface of the steel pipe (base pipe) or t
READ MOREFirst, Common Methods for 3PE Anti-corrosion Steel Pipes1. Steel pipe corrosion protection generally employs two main methods: external coating and cathodic protection.2. Although most of the steel pipe's surface is covered by the coating, even a small leak can lead to an incredible corrosion rate,
READ MOREOil casing, besides its use in oil extraction, also serves as a pipeline for transporting raw materials. To enhance the quality of oil casing, every step of the production process is crucial, especially temperature control, which must be strictly adhered to. Typically, oil casing employs sub-critica
