  • Internal anti-corrosion treatment method for large diameter spiral steel pipe

    Internal anti-corrosion treatment method for large diameter spiral steel pipe

    The construction of cement mortar fabric should usually be carried out after the spiral pipe has been laid, the pressure test has passed, and the covering soil has been compacted according to the planning requirements. Due to the small stiffness and thin wall of the steel pipe, the pipe must be i...

    How to prevent corrosion when welding galvanized steel pipes

    Anti-corrosion of galvanized steel pipe welding: after surface treatment, thermal spray zinc. If galvanizing is not possible on site, you can follow on-site anti-corrosion methods: apply epoxy zinc-rich primer, epoxy mica iron intermediate paint, and polyurethane topcoat. The thickness refers to ...

  • Large-diameter seamless steel pipe is a steel product formed by cold drawing, cold rolling, etc.

    Large-diameter seamless steel pipe is a steel product formed by cold drawing, cold rolling, etc.

    Large-diameter seamless steel pipes are steel products formed by cold processing such as cold drawing and cold rolling. The state in which they are delivered directly without any heat treatment is called cold drawn or cold rolled state. Compared with the hot-rolled (forged) state, steel in the co...

  • The main uses of thick-walled steel pipes

    The main uses of thick-walled steel pipes

    The biggest difference between thick-walled steel pipes and thin-walled steel pipes is the thickness of the pipe wall. Steel pipes with wall diameters greater than 0.02 are generally called thick-walled steel pipes. Thick-walled steel pipes have a very wide range of uses. Because their pipe walls...

  • What is the difference between cold-drawn steel pipe and hot-rolled steel pipe

    What is the difference between cold-drawn steel pipe and hot-rolled steel pipe

    (1) The difference between hot working and cold working: hot rolling is hot working, and cold drawing is cold working. The main difference: is that hot rolling is rolling above the recrystallization temperature, cold rolling is rolling below the recrystallization temperature, and cold rolling is ...
