GB/T3091 Q195 ERW Welded Steel Pipes For Low Pressure Liquid Delivery

Welded Steel Pipes

Weled steel pipes for low pressure liquid delivery is also called general welded pipe, commonly known as the clarinet. It is used to transport oil, gas, air, water and heating steam and other general low pressure fluid and other purposes of welded steel pipe.Steel tube is divided into ordinary steel pipe and increasing pipe according towall thickness ;According to side form,it is divided into steel pipe (light pipe) without thread and steel pipe with thread.The specifications of the steel tube is indicated by nominal diameter (mm), nominal diameter is the approximation of inner diameter,traditionally used in inch, such as 11/2.Weled steel pipes for low pressure liquid delivery are also used as the original pipe of low pressure Liquid Delivery Weled Steel Pipe with galvanizedbesides used for deliver liquid directly.

Application:Welded steel pipes delivering low pressure liquid such as water,air,heating steam and gasses.
