In power equipment, condensers play a vital role, and stainless steel welded pipes, as an important part of condensers, have attracted widespread attention and application.
This article will explore in depth various aspects of stainless steel welded pipes for power equipment condensers, including its production equipment, process methods, product advantages and specific applications.
1. GNEE stainless steel welded pipe production equipment
Usually, the production line will contain multiple key components, such as base, protective box, support fixture and grinding assembly.
2. Production process method
The production process of stainless steel welded pipes mainly includes the following steps: First, install the two ends of the stainless steel welded pipe on two support fixtures respectively, and adjust their positions so that the weld is directly below.
Then, start the electric telescopic rod and move the grinding assembly down to the weld.
Next, use the grinding motor to drive the grinding roller to rotate and start fine grinding of the weld.
At the same time, the first servo motor drives the support cylinder to rotate, so that the stainless steel welded pipe rotates accordingly, so that the grinding assembly can fully process the entire weld.
Finally, the waste dust generated is absorbed and purified by the air purification mechanism to ensure the cleanliness of the production environment.
3. Advantages of stainless steel condenser tubes
High strength: The strength of the welded pipe is improved through online annealing and solution treatment, so that it can maintain stable performance even under high pressure.
Smooth inner wall: Mechanical fine inner polishing technology ensures that the inner wall is smooth and traceless, reducing the resistance and scaling possibility during fluid flow.
Corrosion resistance: The selection of high-quality raw materials and advanced welding technology makes the stainless steel welded pipe have excellent corrosion resistance. After 1000 hours of salt spray test, there is no corrosion on the surface.
Complete specifications: The product specifications are diverse, with a diameter range from Ф14mm to 40mm and a wall thickness range from 0.5mm to 2.0mm, which can meet the needs of different application scenarios.
4. Application fields
Chemical industry: used to manufacture corrosion-resistant reactors, pipelines and other equipment.
Petroleum and natural gas industry: pipelines used to transport corrosive media.
Power engineering: used for heat transfer elements in boiler feed water preheaters and other heat exchange equipment.
Biopharmaceuticals: Suitable for pharmaceutical equipment with high cleanliness requirements.
Food industry: Used in the construction of food processing equipment to ensure food safety and hygiene.
5. Inspection methods
Appearance inspection: Check whether there are cracks, dents and other problems on the surface of the welded pipe.
Dimension measurement: Use precision instruments to measure whether the outer diameter, wall thickness and other parameters of the welded pipe meet the requirements.
Pressure test: Test the sealing and pressure bearing capacity of the welded pipe through a water pressure test.
Eddy current flaw detection: Use the principle of electromagnetic induction to check whether there are defects inside the welded pipe.
Mechanical property test: Test the tensile strength, yield strength and other mechanical indicators of the welded pipe.
