Stainless steel pipes: seamless pipes and seamed pipes (straight seam welded pipes, decorative pipes, welded pipes, welded pipes, bright pipes). There are more than 200 standard specifications of stainless steel pipes, both large and small. Small pipes are more expensive, especially capillary pipes. .Capillary tubes are best made of 304 material, otherwise the tubes are prone to bursting. Non-standard specifications of tubes can also be customized for customers. Seamless tubes are mainly used in industry. The surface is matte and not bright. The surface of seamed tubes is bright. There is a very thin welding line inside the pipe, commonly known as welded pipe, which is mainly used for decorative materials. There are also industrial fluid pipes, whose pressure resistance depends on the wall thickness. 310 and 310S are high temperature resistant pipes. They can be used normally below 1080 degrees. The maximum temperature resistance reaches 1150 degrees.
