Large diameter thick-walled seamless steel pipe   refers to a pipe that out diameter is above 159mm. With plastic coating options such as polyvinyl chloride (PVC), polyethylene (PE), and epoxy (EPOZY), they offer exceptional properties such as corrosion resistance, adhesion, and durability. The benefits of large diameter seamless pipes are unparalleled. They are resistant to chemical corrosion, non-toxic, rust-free, wear-resistant, and have excellent impact resistance. With a smooth surface that reduces transmission resistance, these pipes increase traffic and transport efficiency while decreasing delivery pressure losses. Solvent-free coating ensures no substance oozing, keeping your transmission medium clean and pure. They can withstand hot and cold cycles from -40°C to 80°C without aging or cracking, making them ideal for challenging environments. 🌬️ Widely used in various industries including tap water, natural gas, petroleum, chemical, and telecommunications, large diameter s...

The most commonly used method of connecting   large-diameter spiral steel pipes   is welding. However, manufacturers also use threaded connections, flange connections, socket connections, and groove connections in projects. In the post,   Xiangjiasteel   would like to introduce you some details about three main connections. 1. Welding and Flange Connection Welding and flange connections are traditional methods of connecting spiral pipes. These methods do not fully meet market demands in terms of safety, sealing performance, cost efficiency, and repair efficiency. They are mainly used for water transmission pipelines, oil and gas pipelines, chemical pipelines, and power pipelines. 2. Clamp Fitting Connection Clamp fitting connections are an advanced method of pipe connections. They can be used for both exposed and buried installations, accommodating both rigid and flexible joints.  3. Groove Fitting Connection Groove fitting connections, also known as clamp conne...
