Problems solved by technology

[0003] When installing pipelines, for pipelines with small diameters, partial fixation is required at intervals. At this time, pipe clamps are generally used for fixing, but with the influence of the surrounding environment over time, acid-base environment or high-temperature and low-temperature environments, the pipe clamp A certain corrosion and aging effect is produced. At this time, the pipe clamp is easy to loosen, shift, or even fall off, which affects the normal and practical use of the pipeline, and even creates certain safety hazards.

[0030] A fixing bracket 2 is provided on the outer side of the two clamping sections. The fixing bracket 2 includes a fixing part and a clamping part. The fixing part is a pull ring with an opening on one side. The upper end of the pull ring is provided with a fixing hole. Th...

Embodiment 2

[0034] This embodiment provides a manufacturing process of a corrosion-resistant high-strength support and hanger assembly. The specific processing process of the pipe clamp 4 is as follows:

[0035] Step 1: Select the composition and mass percentage of the steel sheet blank:

[0036] C: 0.03%, B: 0.045%, Mn: 0.32%, Si: 0.101%, P: 0.001%, S: 0.001%, Nb: 0.05%, V: 0.022%, W: 0.015%, Ti: 0.28%, Al: 0.54%, Cu: 0.084%, Ni: 0.71%, Cr: 4.13%, Mo: 0.21%, lanthanum: 0.015%, cerium: 0.007%, neodymium: 0.001%, the balance is Fe and unavoidable impurities;

[0037] Step 2: Rolling:

[0038] The rough rolling temperature is 1270°C, the finishing temperature is 960°C, and the final rolling temperature is 830°C. After hot rolling, oil cooling is used first, and the steel plate is cooled to 580°C at a cooling rate of 10°C / s, and then air-cooled. Cool the steel plate to 330℃ with a cooling rate of 6℃ / s, and finally use water cooling to cool the steel plate to room temperature at a cooling rate of 3℃...

Embodiment 3

[0045] This embodiment provides a manufacturing process of a corrosion-resistant high-strength support and hanger assembly. The specific processing process of the pipe clamp 4 is as follows:

[0046] Step 1: Select the composition and mass percentage of the steel sheet blank:

[0047] C: 0.05%, B: 0.047%, Mn: 0.34%, Si: 0.103%, P: 0.002%, S: 0.003%, Nb: 0.07%, V: 0.026%, W: 0.019%, Ti: 0.31%, Al: 0.58%, Cu: 0.086%, Ni: 0.75%, Cr: 4.15%, Mo: 0.23%, lanthanum: 0.017%, cerium: 0.009%, neodymium: 0.003%, the balance is Fe and unavoidable impurities;

[0048] Step 2: Rolling:

[0049] The rough rolling temperature is 1290°C, the finishing temperature is 980°C, and the final rolling temperature is 850°C. After hot rolling, oil cooling is used first, and the steel plate is cooled to 620°C at a cooling rate of 12°C / s, and then air-cooled. Cool the steel plate to 350℃ with a cooling rate of 8℃ / s, and finally use water cooling to cool the steel plate to room temperature at a cooling rate of 6℃...
