Straight seam steel pipe is a kind of welded steel pipe that is transformed into a cylindrical shape after forming a hot-rolled steel coil through a forming machine. The high-frequency current skin effect and proximity effect or arc combustion under the flux layer are used for welding, so that the edge of the tube blank is heated and melted under a certain extrusion pressure and finally cooled and formed. Petroleum, metallurgy, construction, coal mines, ports, machinery and other industries are widely used in oil and gas transportation, low-pressure water gas transportation, mining fluid transportation, belt conveyors, automobile drive shafts and other industries.

Longitudinal welded pipe equipment plays an important role in people's life and work. However, the maintenance of straight seam steel pipes has always been a headache. Let us understand the precautions in the maintenance process.

1. Choose the right location and warehouse

①The place and warehouse for storing steel pipes should be clean, free of water, and far away from factories and mines that produce harmful gases and dust. Weeds and debris should be removed on site to keep the steel pipes clean.

②Do not stack corrosive substances such as acid, alkali, salt, cement, etc. on the steel pipe in the warehouse. Different types of steel pipes should be stacked separately to prevent confusion and contact corrosion.

③Large section steel, rails, faded steel plates, large diameter steel pipes, forgings, etc. can be stacked in the open air.

④Small and medium steel pipes, metal wires, steel wires, medium-diameter steel pipes, steel wires and steel ropes can be stored in a well-ventilated material shed, but underlays must be installed.

⑤You can put some small steel pipes, steel strips, silicon steel plates, steel plates, small or thin-walled steel pipes, various types of cold-rolled and cold-drawn steel pipes, and high-priced and easily corrosive metal products inventory.

⑥ Choose a warehouse based on geographic location.

⑦The warehouse should be ventilated on sunny days, and closed on cloudy and rainy days, and a proper storage environment should be maintained.

2. Reasonable stacking, put first in first

①The principle of stacking is that under stable and safe stacking conditions, stacking should be carried out according to varieties and specifications, and materials of different varieties should be stacked separately to avoid confusion and mutual corrosion.

②It is strictly forbidden to store items corrosive to steel pipes near the stacking position.

③The bottom of the pile should be high, strong and flat to prevent the material from being damp or deformed.

④Similar materials are stacked in the order of storage, and the principle of first in, first out is realized.

⑤For section steel stacked in the open, there must be wooden mats or stone bars underneath, and the stacking surface should be slightly inclined to facilitate drainage, and attention should be paid to the flatness of the material to prevent bending and deformation.

⑥The stacking height of manual operation should not exceed 1.2m, the stacking height of mechanical operation should not exceed 1.5m, and the stacking width should not exceed 2.5m.

⑦There should be a certain passage between the stacks, the width is usually 0.5 meters, and the approach road depends on the size of the materials and transportation machinery, usually 1.5-2 meters.

⑧The bottom is raised, the warehouse is a concrete floor, and the height is 0.1m; if it is muddy, it must be filled with O. 20.5m. If it is a wilderness, the cement floor is raised by 0.30.5m, and the sand and mud surface is raised by 0.50.7m.

⑨ Angle steel and channel steel in the open air environment should be bent downward, that is, the steel pipe should be downward and erect. The channel surface of the steel pipe should not face upwards to prevent the accumulated water from rusting.

3. Packing and protective layer of protective materials

The preservatives or other electroplating and packing used by the steel plant before leaving the factory are important measures to prevent the material from rusting. During transportation and loading and unloading, care should be taken to protect it to extend the storage period of the material.

4. Keep the warehouse clean and strengthen the maintenance of materials

①Before entering the warehouse, care should be taken to prevent rainwater from getting wet or mixed with impurities, and according to its performance, use different methods to clean contaminated materials. For example, available high-hardness steel wire brushes, cloth, cotton, etc.

②The materials should be checked frequently after storage. If there is rust, please remove the rust layer.

③After the surface of ordinary steel pipes are cleaned, there is no need to apply oil, but the inner and outer surfaces of high-quality steel pipes, alloy steel, thin-walled pipes, alloy steel pipes, etc. must be coated with anti-rust oil.

Straight seam steel pipes are a crucial component in various industries, such as oil and gas, construction, and water transport. These durable and versatile pipes need proper maintenance to ensure their longevity and efficiency. In this blog post, we will discuss the precautions necessary during the maintenance process of straight seam steel pipes. Whether you're a seasoned professional or just starting with maintaining these tubes, this article will provide valuable insights on how to keep them functioning optimally while avoiding costly repairs or replacements. Let's dive right into it!

Control of straight seam steel tube

Control of straight seam steel tubes is an essential aspect of their maintenance process. One crucial step in controlling these pipes is regular inspection to identify any defects or damages that may cause leakage or failure. Inspection can be done visually, or through ultrasonic or x-ray methods, depending on the type and size of the tube.

Another critical control measure for straight seam steel tubes is monitoring their temperature during operation. Overheating can cause the metal to weaken and lead to structural failures, while too low temperatures can result in freezing and cracking when transporting liquids. It's vital to keep track of the temperature at different stages along with the pipeline system.

Moreover, proper handling during transportation and installation also contributes significantly to maintaining the quality of straight seam steel tubes. These pipes should be transported using appropriate equipment such as cranes that can support their weight without causing damage.

In summary, controlling straight seam steel tubes involves inspecting them regularly for defects and damages, monitoring their temperature during operation and ensuring they are handled correctly during transportation and installation. By following these precautions carefully, we can prolong the lifespan of our straight seam steel pipes while avoiding costly repairs or replacements down the road.

Adjustment of straight seam steel tube

Adjustment of straight seam steel tubes is an essential process in the maintenance and installation phase. It involves fine-tuning the alignment of the pipes to ensure that they are in perfect shape for their intended use. The adjustment process typically requires high levels of precision as even minor errors can lead to significant problems later on.

One crucial aspect of adjusting straight seam steel tube is ensuring that all angles are within tolerance limits. This requires using specialized tools, such as gauges and laser measuring devices, which allow for accurate readings. Any deviations from these limits would require corrective action to be taken before proceeding with further adjustments.

Another important consideration during adjustment is welding quality control. Welding defects can occur due to various reasons, including improper handling or inadequate preparation before welding takes place. Therefore, regular checks must be carried out to identify any signs of poor weld quality and take corrective measures where necessary.

It's worth mentioning that proper documentation should accompany every adjustment process performed on a straight seam steel pipe system. This documentation serves as a reference point for future inspections and ensures that maintenance procedures are adhered to consistently over time.

Proper adjustment techniques are critical when maintaining straight seam steel tubes' integrity throughout their usable lifespan. These methods ensure optimal performance while minimizing potential risks associated with poorly adjusted pipes."
