Application
LSAW steel pipe is mainly used for gas and oil transportation pipelines such as petroleum and natural gas delivery pipeline both on land and in the sea, city pipe network, water-coal-slurry pipeline in mining projects, high voltage power transmission line, etc. It is also suitable for steel structures of wind power system, bridge and high speed railway.
Our product meets the requirements of “west to east natural gas transmission project” which is a large and important project for natural gas transmission in China”. Our LSAW steel tubes can replace imported products in China and are exported to many countries as well.
Our LSAW steel pipe is mainly made of Q235B or Q345B steel material and complies with the standard of API5L GR.B. The tube end can be plain or bevel. Surface treatment such as paint spraying, 3PE anticorrosion, oil applying, hot-dip galvanizing, electric galvanizing and ink antirust coating are applied in our longitudinal seam steel tube.
