LSAW steel pipe is a kind of welded steel pipe. It refers to the steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The hot rolled steel coil is formed by the forming machine, and then the steel coil is transformed into a cylinder shape. Welding is carried out by using high-frequency current skin effect and proximity effect or arc combustion under the flux layer, so that the edges of the pipe billet are heated and melted under a certain extrusion pressure, melted, and finally cooled and shaped. Yes. Petroleum, metallurgy, construction, coal mining, ports, machinery and other industries are widely used in oil and gas transportation, low-pressure water and gas transportation, mine fluid transportation, belt conveyor, automobile drive shaft and other industries.
LSAW pipe equipment plays an important role in people's life and work, but the maintenance of LSAW pipe has always been a headache. Let's learn about the considerations in the maintenance process.
Choose the right place and warehouse:
The place and warehouse where the steel pipe is stored should be clean, free of water, and far away from factories and mines that produce harmful gases and dust. The site should be cleared of weeds and debris to keep the steel pipe clean.
No corrosive materials such as acid, alkali, salt, cement and other corrosive materials shall be stacked together with the warehouse steel pipe. Different types of steel pipe should be stacked separately to prevent confusion and contact corrosion.
Large section steel, steel rails, annealed steel plates, large diameter steel pipes, forgings, etc. can be stacked in the open air.
Small and medium sections of steel, wire rod, rebar, medium diameter steel pipe, steel wire and steel wire rope can be stored in a well-ventilated material shed, but must be installed with lower mats. Technical requirements related to the maintenance of straight seam steel pipe
Some small steel pipes, steel plates, steel strips, silicon steel sheets, small or thin-walled steel tubes, various types of cold-rolled, cold-drawn steel tubes and high-priced, corrosion-prone metal products can be stored in the warehouse.
Warehouses are selected according to geographic conditions, and general closed warehouses are generally used, i.e., warehouses with walls on the roof, tight doors and windows, and ventilation devices.
The warehouse should pay attention to the sunny day ventilation, rainy day closed warehouse, to maintain a suitable storage environment.
