The spiral pipe welding process is also the difference between SSAW and LSAW, which is the form of welding seam. The difference between SAW and ERW is the difference of welding process. According to the production method, steel pipe can be divided into two categories: seamless steel pipe and welded steel pipe. According to the production method, seamless steel pipe can be divided into: hot rolled seamless pipe, cold drawn pipe, precision steel pipe, hot expansion pipe, cold spinning pipe and extrusion pipe. Seamless steel tubes are made of high quality carbon steel or alloy steel.Commonly used standards of the spiral steel pipe can be divided into: SY/T5037-2008 (solid, also known as the common fluid conveying pipe with spiral seam submerged arc welding steel pipe), GB/T9711.1-2008 (national standard, also known as oil and gas industry conveying pipe delivery technical conditions in the first part: grade A steel pipe (GB/T9711.2 strict grade B steel pipe)), API 5 l (American petroleum institute, also known as the pipeline steel pipe; Two grades: PSL1 and PSL2), SY/ t5040-2008 (spiral welded steel pipe for pile)Spiral steel tube q235b spiral steel tube

Large diameter welded pipe is mostly spiral welding.

The commonly used helical pipe materials for structural reinforcement are as follows: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb.

The reinforced spiral pipe used for structure is mainly used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. Liquid transport: water supply, drainage, sewage treatment engineering, mud transport, Marine water transport. For gas transmission: gas, steam, LPG. For structure: piling pipe and bridge; Wharf, road, building structure pipe, Marine piling pipe, etc


Q: How are steel pipes recycled at the end of their life cycle?
Steel pipes are typically recycled at the end of their life cycle through a process called steel scrap recycling. This involves collecting the used pipes, cleaning them to remove any contaminants, and then shredding or cutting them into smaller pieces. These pieces are then melted down in a furnace to create new steel products, including pipes. The recycled steel pipes are then ready for use in various industries, reducing the need for new production and conserving valuable resources.
Q: How are steel pipes coated to prevent corrosion?
Steel pipes are coated to prevent corrosion through a process called galvanization, where a layer of zinc is applied to the surface of the pipes. This zinc coating acts as a protective barrier, preventing the steel from coming into direct contact with moisture and other corrosive elements in the environment.
Q: How do steel pipes handle vibrations?
Steel pipes are known for their ability to handle vibrations effectively. Due to their strong and rigid nature, steel pipes can withstand various types of vibrations, including mechanical vibrations and seismic activities. The resilience of steel pipes is attributed to their structural integrity and strength. Steel pipes have high tensile strength, which enables them to resist deformation or breakage when subjected to vibrations. They are also resistant to fatigue, meaning they can endure repeated vibrations without experiencing any significant damage. This makes steel pipes ideal for applications that involve constant or cyclic vibrations, such as in industrial settings or for transportation of fluids through pipelines. Moreover, steel pipes have the advantage of being able to dampen vibrations due to their mass. The weight of the steel pipe helps absorb and dissipate the energy produced by vibrations, preventing excessive movement or oscillation. This damping effect contributes to the overall stability and durability of the pipe system. To further enhance the ability of steel pipes to handle vibrations, various measures can be taken. These may include the use of vibration isolators or dampers, which are devices designed to reduce the transmission of vibrations from the surrounding environment. Additionally, proper installation techniques and regular maintenance can help ensure that steel pipes continue to perform optimally under vibration-prone conditions. In summary, steel pipes are well-suited to handle vibrations due to their strength, resistance to fatigue, and ability to dampen vibrations. Their robustness and durability make them a reliable choice for applications where vibrations are a concern, ensuring the safe and efficient transport of fluids or materials.
Q: Heating system DN40 and DN32 welded steel pipe how to connect?
Is the wire: also called pipe thread connection, the malleable steel pipe fittings, malleable iron is the thread connection using DN40X32 diameter hoop.
Q: What are the different coating options for steel pipes?
There are several different coating options available for steel pipes, including fusion bonded epoxy (FBE) coating, three-layer polyethylene (3LPE) coating, three-layer polypropylene (3LPP) coating, coal tar enamel (CTE) coating, and zinc coating. These coatings help to protect the steel pipes from corrosion and extend their lifespan.
Q: How many meters per ton of steel tube?
Formula of steel tube: (outside diameter wall thickness) * wall thickness *0.02466= per meter weight1000 divided by the weight per metre is how many meters per ton
Q: How do you calculate the pipe flow rate for steel pipes?
To calculate the pipe flow rate for steel pipes, you can use the Hazen-Williams equation or the Darcy-Weisbach equation. These equations take into consideration factors such as the pipe diameter, length, roughness, and the pressure difference between the two ends of the pipe. By plugging in these values into the respective equation, you can determine the flow rate of the fluid passing through the steel pipe.
Q: How are steel pipes insulated for thermal efficiency?
Steel pipes are insulated for thermal efficiency by adding a layer of insulation material around them. This insulation helps to reduce heat transfer through the pipes, preventing energy loss and maintaining the desired temperature.
Q: How are steel pipes transported?
Steel pipes can be transported through different means depending on their size, weight, and the distance they need to cover. The primary modes of transportation for steel pipes are trucks, trains, and ships. For shorter distances, trucks are often used to transport steel pipes. The pipes are loaded onto flatbed or specialized trailers designed to securely hold and transport them. Trucks are convenient for transporting steel pipes to nearby locations or construction sites, as they can easily navigate local roads and highways. For longer distances, trains are the preferred mode of transportation. Steel pipes are loaded onto flatcars, which are specifically designed to carry heavy loads. Trains offer a cost-effective and efficient means of transporting large quantities of steel pipes over long distances. They can accommodate pipes of various lengths and diameters, making them a versatile option. When it comes to international shipments or transportation over bodies of water, ships are commonly used. Steel pipes can be loaded into shipping containers or onto the deck of cargo ships. Shipping containers provide protection from weather conditions and ensure the pipes remain secure during transit. Specialized ships equipped with cranes can handle large and heavy pipes, making the transportation of oversized steel pipes possible. In certain cases, pipelines can be constructed to transport steel pipes directly from the manufacturing facility to the desired location. This method is commonly used for oil, gas, or water pipelines. By laying the pipes underground, the need for separate transportation is eliminated. Overall, the transportation of steel pipes involves a range of methods, including trucks, trains, ships, and pipelines. The choice of method depends on factors such as distance, quantity, and project requirements. Each method offers its own advantages and is selected based on considerations such as cost, efficiency, and logistics.
Q: What is the difference between steel pipes and aluminum pipes?
The main difference between steel pipes and aluminum pipes lies in their material composition. Steel pipes are made of an alloy primarily composed of iron and carbon, making them strong, durable, and resistant to corrosion. On the other hand, aluminum pipes are made of aluminum, which is a lightweight metal known for its excellent corrosion resistance and high thermal conductivity. Aluminum pipes are typically used in applications that require lightweight materials or where corrosion resistance is crucial, while steel pipes are commonly used in heavy-duty applications that require strength and durability.
