Characteristics and storage requirements of cold drawn seamless pipes

Seamless steel pipes are divided into cold-drawn seamless pipes and hot-rolled seamless pipes according to the production process. Cold drawn seamless pipes are seamless steel pipes with a circular cross-section made by cold drawing. Its name refers to the shape of steel pipes, such as thick-walled cold-drawn seamless pipes, thin-walled cold-drawn seamless pipes, etc. Cold drawn seamless pipes are widely used in the production of various structural parts, tools and mechanical parts. Compared with round pipes, cold drawn seamless pipes generally have larger moments of inertia and section modulus, have greater torsion resistance, save materials, and improve efficiency. They can be directly processed without deep processing in factories or mechanical processing plants. Use, reduce workload, improve work efficiency, and be loved by terminal demand.

  Storage requirements for cold drawn seamless pipes

  1. For the site or warehouse where seamless pipe products are stored, it should be selected in a clean and tidy place with unobstructed drainage, away from factories and mines with harmful gases or dust. Weeds and all debris should be wiped out on the ground to keep the seamless pipe tidy.

  2. In the warehouse, it should not be stacked with acid, alkali, salt, sensitive soil and other materials that are corrosive to seamless pipes. Different types of steel should be stacked separately to avoid confusion and avoid contact with corrosive objects

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

  4. Small and medium-sized steel bars, wire rods, steel bars, medium-diameter steel pipes, steel wires and wire ropes, etc., can be stored and placed in a shed with satisfactory ventilation, remember the upper and lower pads

  5. Small-scale steels, thin steel plates, steel strips, small-diameter or special-shaped steel pipes, various cold-rolled and cold-drawn steels, and expensive and corrosive metal products can be stored in the warehouse

  6. The warehouse should be selected according to the geographical conditions, and the ordinary closed warehouse is considered appropriate, that is, a warehouse with a roof, a fence, doors and windows, and a ventilation device.

  7. The warehouse is required to always maintain a suitable storage background, pay attention to ventilation in sunny days, and close it to prevent moisture in rainy days.

  Seamless pipes can be divided into round pipes and special-shaped pipes according to different cross-sectional area shapes. Since the circle area is the largest under the condition of the same circumference, more fluid can be transported with a circular tube.

  Cold drawn seamless pipes are widely used in automobiles, motorcycles, electric vehicles, petrochemicals, electric power, ships, aerospace, bearings, pneumatic components, seamless steel pipes for medium and low pressure boilers, etc. It can also be applied to steel sleeves, bearings, hydraulics, etc. Mechanical processing and other fields!
