Fire-fighting pipeline refers to the pipeline material used for fire-fighting, connecting fire-fighting equipment and equipment, and transporting fire-fighting water, gas or other media.

The eddy current detection of seamless steel pipe is to use the principle of electromagnetic induction to excite the probe coil with high-frequency sine wave current. When the probe is close to the metal surface, the alternating magnetic field around the line pattern will generate an induced current on the metal surface.

After the SSAW steel pipes are transported to the site, the pipes are first arranged according to the location of the equipment and pipe fittings, and the specific length of each steel pipe is measured on site, and the specific size and arrangement position are marked. In order to be seated according to the number at the interface, a crane is used to lower the pipe, and nylon slings are used for hoisting during the lowering process to protect the pipe insulation layer.

Thermal expansion is a processing method of carbon steel pipe, which is to process small-diameter carbon steel pipe into large-diameter carbon steel pipe. The mechanical properties of hot-expanded carbon steel pipes are slightly worse than those of hot-rolled carbon steel pipes.

Piercing is the first process of deformation of hot-rolled seamless steel pipe, and its function is to pierce the solid tube blank into a hollow capillary tube.

Non-magnetic galvanized seamless pipe is a common metal pipe with excellent mechanical properties and corrosion resistance.
