Description: Stainless steel pipe is a kind of use is more of a pipe material, generally in order to guarantee the quality of the products we are needed for welding operation before use, to master the right operation method is very important, as is the use of this late for us, then we have to get to know the stainless steel pipe before welding are what need to prepare:
1, in order to guarantee the safety of the staff in the welding of product, staff must wear professional clothes to do a good job of protection is a key point.
2, using electric grinding tools need to check whether the grinding wheel piece is loose, whether to need to replace grinding wheel.
3, stainless steel pipe should be wearing a seatbelt, the work high above 38 tube fitting the build-up of hands and feet should be safe and reliable.
4, the work high above the below if there are inflammable and explosive articles, should be ahead of the measures to prevent splash content dropped. 5, welding line shall not be connected to the device with induction coil, connected to the electrode holder part of the arc wounded steel tube should be placed and reliable so as not to work.
304 stainless steel tube in the welding needs pay attention to what aspects?
1. The distinction between bottom and cladding in welding process, with their respective applicable welding materials for welding.
2. In order to ensure the corrosion resistance of coating, the coating of the weld composition should be like the cladding steel components.
3. In the two layers together, in order to avoid the cladding will be the underlying diluted, make the corrosion resistance is reduced, thus the welding of the key is to deal with two layers of border area of welding, can be in the bottom of transition layer between the coating and the weld.
4. Heat treatment after welding of large thickness of stainless steel plate welded components, heat treatment after welding can eliminate the welding residual stress.
5. Pay attention to the heat treatment at high temperature, would amount to a cable on one side of carbon steel decarburization in body, lower the progress; While at the side of the stainless steel by carburizing and hardening is crisp, the impact toughness decreases, become a welded joint in danger of failure, it is not desirable.
2018 stainless steel clad pipe social inventory once climbed to 10.8239 million tons of high, but as the downstream starts to ascend, end demand gradually released. Mysteel data show that as of April 19, the stainless steel clad pipe inventory has fallen to society 8.0455 million tons. However, the total inventory is long into the downlink channel, but high inventory base is still the important resistance of steel prices. After march, as environmental limit production, market game center of gravity of steel trade business to the steel trade between shang and stainless steel pipe factory.
Transfer between. At present, the spot price is close to the steel trade merchants had brass tube fitting winter cost line, even some merchants losses, although the merchants sold will is not strong, but the market inventory pressure, some merchants have to sales prices, coupled with part no.
Stainless steel pipe factory has been to resume production, stainless steel clad pipe production continues to increase, so the stainless steel pipe prices recover.
