Q235 Carbon Steel Spiral Pipe Specifications and Applications

Spiral pipes are special steel pipes that are often found on the market. They have a wide range of applications and are often used in pipeline construction or other aspects of construction. So, what type of steel pipe is spiral pipe? Let's learn it below.

Low alloy structural steel or low carbon structural steel strip is rolled into a tube blank at a certain spiral angle. The angle here is also called forming angle, then the pipe joints are welded along the pipe. seams. A kind of steel pipe made from it is called a spiral pipe. Also called spiral welded tube or spiral steel tube. Spiral pipes can use narrower steel strips to produce steel pipes with larger diameters and higher requirements.

Arc welded steel pipe sSpiral joint submerged is a spiral metal pipe that is welded using submerged arc welding technology and has spiral joints on its surface. Spiral joint submerged arc welded steel pipes are often welded in pipelines for fluid transportation, or used as steel structures and pile foundations, etc., and are widely used in construction engineering. water supply, chemical industry, petrochemical industry, agricultural irrigation, electric power industry, urban construction, etc. It is used for transporting liquids and performs functions such as water supply and drainage. When used for gas transportation, it is used to transport gas, steam and liquefied petroleum gas. When used for structural purposes, it is often used as pipes for pilings and bridges in construction; pipes for quais, roads, building structures, etc. It has become an essential element of our daily life and our construction.

The Q235 carbon steel spiral pipe is arc welded under the flux layer. The arc is burned between the welding wire and the flux under the flux layer. The heat generated by the arc is used to melt the welding wire. flow and the base metal, then form one of the spiral steel pipes. Q235 carbon steel spiral pipe has many advantages. For example, due to its double-sided submerged arc welding method, Q235 spiral pipe not only has a highhigh deposition, but also has deep penetration capabilities. protected. Therefore, the quality of the finished product is relatively high, the weld quality is excellent, the density is good, and the weld appearance is flat and smooth, which can meet various welding performance requirements?

Q235 carbon steel spiral pipes are widely used. One is to use automatic double-sided submerged arc welding or single-sided welding to make general submerged arc welded steel pipes for low pressure liquid transportation. used to transport water, gas, natural gas, air, heating oil and steam, etc.

The plastic pipeSpiral joint submerged arc welded steel is the most widely used type of spiral pipe. In addition to this product, the spiral pipes also have other specifications: GB/T9711. .1-1997 (national standard, A grade steel tube), API-5L (American Petroleum Institute standard, pipeline steel tube; divided into two levels: PSL1 and PSL2).

Spiral tubes have been widely used in our market and are indispensable. It has been integrated into every aspect of our life, but spiral pipes are used in different industries and for different purposes, so specifications and standards have become the main identifiers to divide them. From its different specifications, we can also see its complexity and wide range of applications.

What is it which is used in spiral water pusher? Principle

Spiral steel pipe is a type of steel commonly used in industry, construction and other industries. It is a spiral joint steel pipe which is made of steel strip coils as raw material, is extruded at constant temperature and welded by automatic double-sided double-sided submerged arc welding technology thread. Mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. (Baiwo Steel Pipe arranges it for you)

Spiral steel pipes are used for transporting liquids:water supply and drainage. For transporting gas: coal gas, steam, liquefied petroleum gas. Structural use: pipes for piles, bridges; pipes for docks, roads, building structures, etc. Spiral steel pipe factory plays a big role in gas transportation and transportation.

Spiral joint submerged arc welded steel pipes for transporting pressurized fluids are mainly used for pipelines transporting oil and natural gas; Spiral joint high frequency welded steel pipes for conveying pressurized fluids are high frequency welded. frequency lap welding., spiral joint high frequency welded steel pipe used for conveying fluids under pressure. Steel pipes have strong carrying capacity, good plasticity, and are easy to weld and process. Generally, joint submerged arc welded steel pipesSpiral are used for transporting fluids at low pressure. They are manufactured by automatic double-sided submerged arc welding. single-sided welding and are used for water, gas, air and steam. Submerged arc welded steel pipes are used for general transportation of low pressure fluids.

The spiral water elevator uses the lever principle proposed by Archimedes.

The principle of operation is that when the inner spiral rotates, the screw rotates around its own axis on the one hand, and on the other hand it rolls along the inner surface of the socket, forming like a jet of water. sealed chamber.

Each time the screw turns once, the water in the sealed cavity is pushed forward. As the screw continues to turn, the water is squeezed out one sealed chamber to another, and finally the water is drained.

Detailed information:

Archimedes was most likely the world's first expert in mechanics at that time. The person who best understands the principles and applications. It was quite laborious to water the soil. After thinking about it, he invented a method that uses a spiral that rotates in the water pipe to drain the water.

The tool that was sucked up was called the “Archimedes Spiral Water Lifter” by later generations. The Egyptians still use this instrument until today, two thousand years later.

This tool became the ancestor of the later propeller. In Europe at that time, simple machines such as screws, pulleys, levers, gears, etc. were used. were often used in engineering and everyday life.

Archimedes spent a lot of time researching and discovered the concepts of “lever principle” and “torque”. For Archimedes, who often used tools to make machiness, it was very important to apply the theory in life. is child's play.
