ERW Steel Pipes For Low Pressure Liquid Delivery

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.

 

size: OD:10.2-2540mm

         WT: 0.5-65mm

Processing: Steel pipe shall be processed with anyone of longitudinal-seam high-frequency electrical resistance welding,longitudinal-seam submerged arc welding and spiral-seam submerged arc welding.

 

Delivery state:Steel pipes shall be delivered in welded state.Longitudinal-seam high-frequency electrical resistance welded steel pipe may be indelivered seam heat treatment condition.According to requirement of demand side,and through negotiation between both supply and demand sides,steel pipe also may be delivered in bulk heat treatment state and that shall be indicated in contract.

According to requirement of demand side,and through negotiation between both supply and demand sides,steel pipe whose outside diameter is no larger than 508mm also may be delivered with galvanizing or other protective coat,and that shall be indicated in cintract.

Mechanical property requirements:Mechanical property requirements of steel pipe shall comply with those specified in the following table,which of other steel grade shall be determined by supply and demand sides through negotiation.
