At present, anticorrosive steel pipes are one of the commonly used steel pipes. There are mainly 3PE anti -corrosion steel pipes, TEPE anticorrosive steel pipes, epoxy resin anticorrosive steel pipes, etc. So, what do you need to pay attention to during the construction of anticorrosive steel pipes?
1.3PE anticorrosive steel tube spraying technology
At present, most domestic 3PE anti -corrosion steel pipe production technology uses the production and processing process of "epoxy powder spraying, adhesive and polyethylene side squeezing, winding and rolling", because the method of powder and static and thermal spraying does not require rolling, so as to solve the solution The problem of thin coating of the welding steel pipe welded steel pipes of the spiral structure saves a large number of mechanical equipment such as plastic extrusion machines on the production line, and reduced production energy consumption.
Specific construction: The steel pipes after the rust removing the rust are heated at medium temperature to 210 ° C to 220 ° C, and the epoxy powder is still in a melting state. The adhesive and PE are squeezed out into thin slices with a extruder, sprayed and wrapped around the steel pipe, and then flattened with rollers; epoxy powder is in the form of powder, adhesive and PE are in the form of particles. Squeeze out.
2. Epoxy resin anti -corrosion steel tube painting construction construction
Coal -coal magnetic paint anti -corrosion coating is a kind of hot coating anticorrosive material, which uses coal tar, oil washing and asphalt as the main raw material, and additives as an auxiliary materials. It has the advantages of strong attachment, low water absorption, good insulation, anti -bacterial corrosion, anti -plant root penetration, anti -oil and products dissolved, anti -soil stress, anti -cathode stripping, and long service life. Therefore, it is suitable for anti -corrosion of various underground pipelines.
However, in the paint coating of epoxy resin anticorrosive steel pipes, it is necessary to open the thick paper barrel, remove the pieces of surface paint and break it into small pieces. After heating and melting, put it in a container with a mixer to avoid pollution. Use a closed heater slowly and uniformly to avoid direct contact with facial paint and fire source.
3. Safety protection in the construction of anticorrosive steel pipes
During the spraying process, highly scattered paint mist and volatile solvents will be generated. Some small particles in spraying or coating are easily inhaled into the lungs of the human body, which is harmful to human health. On the other hand, it may cause discomfort, headache, dizziness, nausea, vomiting, loss of appetite, and inattention, and may cause varying degrees of toxicity to people's respiratory systems, circulation systems, digestive systems, and reproductive systems.
Therefore, the anti -corrosion steel pipe should pay attention to safety protection during construction, such as wearing protective glasses or protective measures such as anti -virus masks or long tube respirators; wearing appropriate chemical protective gloves can effectively protect the injuries from spray materials or other liquids.
