How to Classified Seamless Steel Pipe

Seamless steel pipe is made of a single piece of metal without seams on the surface.

 According to the production method, seamless steel pipe are divided into hot rolled pipes, cold rolled pipes, cold drawn pipes, extruded pipes, and jacked pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special. Special-shaped pipes include square, oval, triangle,
hexagon, melon, star, and finned pipes. The maximum diameter is 650mm and the minimum diameter is 0.3mm. Depending on the application, there are thick-walled pipes and thin-walled pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemicals, boiler tubes, bearing tubes, and high-precision structural steel pipes for automobiles, tractors, and aviation.

How Do Infrared Thermometers Work?

Infrared Thermometer Basics Infrared thermometers measure temperature from a distance. This distance can be many miles or a fraction of an inch. Infrared thermometers are often used in circumstances when other sorts of thermometers are not practical. If an object is very fragile or dangerous to be near, for example, an infrared thermometer is a good way to get a temperature from a safe distance. What Infrared Thermometers Do Infrared thermometers work based on a phenomenon called black body radiation. Anything at a temperature above absolute zero has molecules inside of it moving around. The higher the temperature, the faster the molecules move. As they move, the molecules emit infrared radiation--a type of electromagnetic radiation below the visible spectrum of light. As they get hotter, they emit more infrared, and even start to emit visible light. That is why heated metal can glow red or even white. Infrared thermometers detect and measure this radiation. How Infrare...

The Difference Between Seamless Steel Pipe and Seam Steel Pipe

Seamless steel pipe , as the name suggests, is a pipe without a seam or a weld-joint. Seam steel pipe are generally welded with a seam. 1. Different Processing Technology: seamless steel pipe is made of high quality carbon steel or alloy steel. The processing technology of seamless steel pipes are cold drawn and hot rolled, and seam steel pipe are generally welded. 2. Different Uses: seamless steel pipes are mainly used as pipelines for conveying fluids, or structural parts in machinery industry, and seam steel pipes are mainly used in construction industry, such as low-pressure fluid, like water, gas, compressed air. But when must to use pressure pipes, seamless steel pipes is the better choice. 3. Different Pressure-bearing: the maximum working pressure that the seamed pipe can withstand is within 20 kg, which is the safest range of use. It is generally used for low-pressure fluids such as water, gas, and compressed air. Seamless steel pipe can withstand ultra-high pre...
