Sharing the packaging process of stainless steel heat exchange tubes
By: mxgy,
The packaging of stainless steel heat exchange tubes should take into account anti-collision, anti-corrosion, and easy handling and storage. It should be operated in a coherent manner according to the actual specifications (such as length and diameter) and transportation needs. Pre treatment should be done first, and then packaging should be completed step by step.
Firstly, the heat exchanger tube needs to be cleaned by blowing away dust and debris inside and outside the tube with high-pressure air. If there is any residual oil residue from processing inside the tube, it should be wiped clean with a neutral cleaning agent and dried to avoid surface contamination caused by oil adsorption impurities during subsequent storage; At the same time, the pipe body should be inspected, and pipes with surface scratches, dents, and other defects should be picked out and stored separately to avoid secondary damage caused by mixing with intact pipes.
Next, choose the packaging method based on the length of the pipes. For short pipes (usually within 1.5 meters), a combination of “bundling+cardboard box/wooden box” is generally used. First, classify the pipes according to their diameter, and bundle them every 10-20 pieces. Wrap 2-3 times with wide (5 centimeters or more) anti-static strapping at 5-10 centimeters on both ends of the pipes, paying attention to the moderate strength. Tie them tightly to prevent looseness and not to crush the pipe body; After binding, put plastic protective caps on both ends of each pipe to prevent the pipe orifice from being knocked, deformed or entering impurities, and then put the whole bundle of pipes into a customized cardboard box or plywood wooden box. The inside of the box is padded with pearl wool or bubble film, and the gaps are filled with foam blocks to prevent the pipes from shaking in the box during transportation.
Long pipes (especially fixed length pipes over 1.5 meters, especially those over 6 meters) need to be fixed with a “frame fixation+wrapping film” method. First, a rectangular frame made of wood or steel should be built on the ground, with a height 3-5 centimeters higher than the diameter of the pipe and a length consistent with the pipe. The pipes should be placed parallel to each other in the frame, and adjacent pipes should be separated by soft rubber pads to prevent the pipes from rubbing against each other and scratching the surface; After arranging, wrap 2-3 layers of thickened PE wrapping film around the overall outer side of the pipe. When wrapping, pull it from one end to the other at a constant speed to ensure that the film surface is tightly attached to the pipe body, which can not only prevent dust and moisture, but also preliminarily fix the pipe; Afterwards, wooden baffles were installed at both ends of the frame, with soft cushioning material pasted on the inside of the baffles. The baffles and frame were fixed with bolts to prevent the pipes from slipping off from both ends. Finally, the specifications, quantity, weight, and warning signs such as “upward” and “handle with care” were marked on the outside of the frame for easy identification during transportation.
In addition, whether it is a short or long tube, attention should be paid to rust prevention during packaging. If the transportation or storage environment has high humidity, desiccant packs should be placed inside the packaging (2-3 packs per cubic meter of space, with each pack weighing more than 50 grams), and after packaging is completed, it should be checked for damage to ensure that the seal is intact; For heat exchange tubes that need to be exported or stored for a long time, a thin layer of anti rust oil (food grade anti rust oil is used for food grade scenarios) can be applied to the tube body first, and then packaged to further enhance the anti-corrosion effect. Finally, the packaging strength can be adjusted according to the actual transportation mode (such as sea or land transportation), such as increasing the thickness of the wooden box during sea transportation to avoid packaging damage caused by humid and bumpy sea environments.
