What is rectangular steel pipe?

Rectangular steel pipe is a hollow long strip of steel, also known as flat tube, flat square tube or square flat tube. In Panama, rectangular steel pipes are often used as pipes for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, compared with other rigid products, rectangular steel pipes are lighter in weight when they have the same bending and torsional strength. Light, so rectangular steel pipes in Panama are also widely used in the manufacture of mechanical parts and engineering structures. In addition, many rectangular steel pipes are used to produce various conventional weapons, barrels, shells, etc.

Classification of rectangular steel pipes

In Panama, rectangular steel pipes are generally divided into seamless rectangular steel pipes and welded rectangular steel pipes (seamed pipes), hot-rolled seamless rectangular steel pipes, cold-drawn seamless rectangular steel pipes, extruded seamless rectangular steel pipes, and welded rectangular steel pipes.

The use of rectangular steel pipe

In Panama, rectangular steel pipes are usually used in construction, machinery manufacturing, steel construction projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, etc. Rectangular steel pipes are widely used, so doing rectangular steel pipe business in Panama is very promising.

Specifications and sizes of rectangular steel pipe

The following are the specifications and sizes of rectangular steel pipe used in Panama for customers' reference.

The weight of rectangular steel pipe

Theoretical weight calculation formula of rectangular steel pipe in Panama: 2[(a-d-2r+π(r+d/2)/2+(b-d-2r+π(r+d/2)/2)x7.85d(kg),a, b is the length and width of the rectangular tube (m), r is the arc radius of the four corners of the tube lumen (m), and d is the wall thickness (mm).

Stacking of rectangular steel pipes at the port

In Panama, rectangular steel pipes are stacked in oblique lines at the yard, with a height of 3 layers.

The size of the pipe pile should be determined according to various conditions such as the size, shape, and convenience of stacking operations.

Height isolation measures should be taken around the pipe pile, and clear warning signs should be set up in prominent places to avoid damage to the steel pipes caused by passing personnel and vehicles during the stacking period.

Padding and support methods for rectangular steel pipes

There are 2 methods for padding and supporting rectangular steel pipes in Panama. See below.

1. Sandbag bottom type

Put the fine sand into fiber bags, and place 8-9 sandbags in parallel at intervals of about 1 meter under each rectangular steel pipe on the bottom layer. After the steel pipes fall on these sandbags, the sandbags can form by themselves under the pressure of gravity. The liner that adapts to the curvature of the steel pipe plays the role of isolation and fixation from the hard ground. For the outermost rows of steel pipes at the bottom of the pipe pile, the number of sandbags for the liner should be increased, and they should be arranged to be higher on the outside and lower on the inside during laying, so that the outermost rows of steel pipes can form inward and central pressure, which is conducive to The tight stacking of steel pipes and the stability of pipe stacks.

2. Wooden trough type

Process one side of the cuboid wooden block into a concave wooden groove according to the curved arc of the rectangular steel pipe, and arrange about 4 pieces according to the length of each pipe as the liner of the bottom steel pipe. However, in view of the high cost of this method, the high damage rate of the wooden tank, and the low recycling rate, it is generally used in combination with sandbags, and is only used together with sandbags in the liners of the outermost rows of steel pipes at the bottom of each pipe stack to further strengthen the pipe stack. Stability to avoid collapse.

Precautions when hoisting rectangular steel pipes

1. When hoisting rectangular steel pipes with hooks, the cushioning material should be cushioned in the contact area (slope), choose one of rubber or aluminum. To protect the pipe ends from damage.

2. The width and depth of the hook should be covered with rubber to protect the pipe end.

3. The speed should be gentle during the lifting process to avoid excessive impact loads, which may cause pits and out-of-roundness on the pipe body and pipe ends.

4. When hoisting rectangular steel pipes, the steel pipes may shake, and rope traction should be used to prevent steel pipe surface damage and other damages.
