- Q: Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
- Seamless steel tube processing technology:1.1 、 hot rolled seamless tubes are usually produced on automatic rolling mills. After checking and cleaning the surface defects, the solid tube is cut into the required length, centring on the end face of the tube blank, then sent to the heating furnace and punched on the piercer. At the same time, the hole rotates and advances continuously. Under the action of the roller and the plug, the inner cavity of the pipe blank is gradually formed, and the cavity is called the capillary. Sent to the automatic tube rolling mill on rolling. Finally, the thickness of the whole machine is the same, and the diameter of the sizing machine is determined to meet the specifications. It is an advanced method to produce seamless steel tube by continuous rolling mill.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold rolling is usually carried out on a two roller mill, where the steel tube is rolled in the annular groove made of variable cross section, round hole groove and stationary conical head. Cold drawing is usually performed in single chain or double chain cold drawn machines from 0.5 to 100T.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller hole extrusion. This method can produce smaller diameter steel pipe.Seamless steel pipe use: mainly used to transport fluid pipeline or structural parts.The main use of steel pipe joints (steel) two welded together, so the price is cheap, widely used.
- Q: What is the difference between steel pipes and PVC pipes?
- Steel pipes and PVC pipes differ in material composition and their respective properties. Steel pipes are made from a combination of iron and carbon, providing them with high strength and durability. They are suitable for carrying pressurized fluids and can withstand extreme temperatures. On the other hand, PVC pipes are made from a synthetic plastic material called polyvinyl chloride. They are lightweight, easy to install, and resistant to corrosion and chemicals. PVC pipes are commonly used for drainage systems, irrigation, and household plumbing.
- Q: What are the different methods of pipe inspection for steel pipes?
- Steel pipes can be inspected using various methods. Here are some commonly employed techniques: 1. Visual Inspection: Trained inspectors visually examine both the exterior and interior of the pipe to detect any visible defects or abnormalities. This preliminary method is often used before more advanced techniques are applied. 2. Magnetic Particle Inspection (MPI): By applying a magnetic field to the steel pipe and iron particles to its surface, inspectors can identify surface cracks or defects. Leakage of magnetic flux caused by these abnormalities can be detected with this method, which is particularly effective for ferromagnetic materials. 3. Ultrasonic Testing (UT): UT is a non-destructive testing method that utilizes high-frequency sound waves to identify internal defects or anomalies in steel pipes. A transducer sends ultrasonic waves into the pipe, and reflections or echoes of the sound waves are analyzed to determine the presence of defects, such as corrosion, cracks, or variations in wall thickness. 4. Radiographic Testing (RT): This method involves using X-rays or gamma rays to create an image of the internal structure of the steel pipe. The resulting image reveals any defects, such as cracks, corrosion, or weld discontinuities. RT is commonly used for inspecting welded joints. 5. Eddy Current Testing (ECT): ECT is a non-destructive testing technique that utilizes electromagnetic induction to detect surface and near-surface defects in steel pipes. By passing a coil carrying an alternating current over the pipe's surface, any changes in electrical conductivity or magnetic field caused by defects are detected and analyzed. 6. Acoustic Emission Testing (AET): AET involves detecting and analyzing high-frequency acoustic signals emitted by materials undergoing deformation or damage. In the case of steel pipes, AET can monitor and identify defects like cracks, leaks, or corrosion by analyzing the acoustic signals emitted during service or under stress. These methods are just a few examples of commonly used techniques for inspecting steel pipes. The choice of method depends on factors such as the type of defect being sought, accessibility of the pipe, desired sensitivity level, and cost and time constraints. Using a combination of inspection techniques is often recommended to ensure a thorough assessment of steel pipes.
