It can be said that more and more industrial enterprises will use seamless steel pipes, and some enterprises have also found that in the process of using such pipes, there may be a situation of corrosion sometimes. Relevant persons in charge also want to know why such a situation occurs.
And if it is transported corroded, how to deal with it is extremely critical. We also all know that the seamless steel pipes used by most companies now are composed of two important parts: transport sensors and transport converters, and there are transported originals, electrode coils and casings.
Industry professionals said that the transmission signal generated by seamless steel pipes during the transportation process is very weak, so it is necessary to ensure that the grounding of key parts of the pipe must be kept clear, and the liquid to be transported must also be conductive. The liquid should not contain more ferromagnetic substances or air bubbles.
Therefore, when some companies are using pipes, one of the reasons why there is a transport error is that on the one hand, the conductivity of the transported liquid is relatively poor, which may lead to unstable transport of pipes, and other On the one hand, the transported liquid has not been processed in advance, and contains more ferromagnetic substances or air bubbles. Such a situation will also cause the pipe to be blocked in transport.
What are the key points of winter construction in low temperature environment? Low-temperature brittleness will cause embrittlement at 0°C and below. If the transportation, loading and unloading, installation and construction of PVC pipes cannot be avoided under low temperature conditions, the selection of low-pressure thin-walled pipes can be avoided in advance, and the use of high-pressure grades should be used as much as possible. The thick-walled pipe to improve the safety factor.
The transfer process avoids impact and pressure. The PVC pipe is very brittle at low temperature. Therefore, when transporting, transferring, loading and unloading at low temperature, it should be handled lightly. Violent operations such as “throwing, falling, dragging, and rolling” are prohibited. The rear exterior is not easy to detect cracks, and the problem can only be found after the hydraulic test.
After the seamless pipe is transported to the construction site, it should be properly stored to avoid contact and conflict between the pipe and sharp objects. People must not trample on the pipe, especially when unloading the thin-walled pipe, to prevent the trampling of the pipe from cracking and internal injury due to embrittlement. Glue is generally used to connect the low temperature steel pipe, and the inner wall of the pipe socket and the outer wall of the pipe are pierced into the part.
At low temperature, a blowtorch can be used to heat the adhesive part to speed up the solidification speed, and the socket can be moved after 2 hours of penetration. The small diameter can be rotated 90° to make the adhesive distribution more uniform, and the medium and large diameters can be pulled in by using an iron rod or a wire tensioner to ensure better adhesion by piercing the bottom of the socket.
