Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

- Q: What is the maximum diameter of steel pipes?
- The maximum diameter of steel pipes can vary depending on the specific manufacturing capabilities, but generally, it can range from a few inches to several feet.
- Q: Could you tell me what difference between SC galvanized steel pipe and MT wire pipe?
- SC galvanized steel pipe, its pipe wall thickness, generally 20 steel pipe in 2.2-2.8mm. Also, we often refer to tap water galvanized steel pipe.MT wire pipe, its pipe wall is thin, generally 20 steel pipe in 1.5-2.2mm.
- Q: Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
- Steel tube Kg/m (including seamless steel tubes and welded tubes) theoretical formula per meter weight: W=0.02466 * S * (D-S)Of which: S - wall thickness (mm), D - steel tube diameter (mm), W - kg / M
- Q: What is the difference between ERW (Electric Resistance Welded) and LSAW (Longitudinal Submerged Arc Welded) steel pipes?
- ERW steel pipes are manufactured by high-frequency electrical currents passing through the metal, resulting in a welded joint. On the other hand, LSAW steel pipes are produced by submerging a metal plate into a welding zone, creating a welded joint through the use of a welding arc. The main difference lies in the welding process, with ERW pipes being more suitable for small to medium-sized diameters, while LSAW pipes are commonly used for larger diameter and thicker-walled applications.
- Q: How are steel pipes measured and sized?
- Steel pipes are commonly measured and sized based on their outer diameter (OD) and wall thickness. The OD is measured using a caliper or tape measure, while the wall thickness can be determined by either a micrometer or ultrasonic thickness gauge. This information is crucial for classifying pipes into various standardized sizes, such as schedule or nominal pipe sizes, which are widely used in the industry.
- Q: How are steel pipes insulated for thermal efficiency?
- Steel pipes are insulated for thermal efficiency by applying a layer of insulating material, such as mineral wool or foam, around the pipe. This insulation helps to reduce heat transfer and prevent energy loss, ensuring that the pipes maintain the desired temperature and improve overall thermal efficiency.
- Q: What are the common methods for cleaning the inner surface of steel pipes?
- There are several common methods for cleaning the inner surface of steel pipes. Some of the most widely used methods include: 1. Mechanical Cleaning: This method involves the use of mechanical tools such as wire brushes, scrapers, or abrasive pads to physically remove debris, rust, or scale from the inner surface of the steel pipe. This method is effective for removing loose or loosely adhered contaminants. 2. Chemical Cleaning: Chemical cleaning involves the use of acidic or alkaline solutions to dissolve or loosen stubborn deposits, rust, or scale on the inner surface of steel pipes. The solution is usually circulated through the pipe for a specific period of time, allowing the chemical to react and break down the contaminants. This method is often used when mechanical cleaning is not sufficient. 3. High-Pressure Water Jetting: In this method, high-pressure water is directed through a nozzle into the steel pipe, effectively removing debris, rust, or scale from the inner surface. The force of the water jet helps dislodge and flush out the contaminants. This method is particularly efficient for cleaning pipes with complex geometries or hard-to-reach areas. 4. Shot Blasting: Shot blasting involves the use of high-speed abrasive particles propelled against the inner surface of the steel pipe to remove rust, scale, or other contaminants. This method is commonly used for larger pipes or pipes with heavy deposits. It provides a thorough and uniform cleaning by removing the surface layer of the steel along with the contaminants. 5. Ultrasonic Cleaning: Ultrasonic cleaning uses high-frequency sound waves to create microscopic bubbles in a cleaning solution. These bubbles implode upon contact with the inner surface of the steel pipe, effectively loosening and removing contaminants. This method is particularly effective for cleaning small-diameter pipes or pipes with intricate details. It is important to note that the selection of the cleaning method depends on various factors such as the type and extent of contamination, pipe size and geometry, and the desired level of cleanliness. Additionally, proper safety measures should always be taken when performing any cleaning method to ensure the protection of workers and the integrity of the steel pipes.
- Q: How are steel pipes used in the manufacturing of telecommunications infrastructure?
- Steel pipes are commonly used in the manufacturing of telecommunications infrastructure for various purposes such as underground cable protection, overhead cable support, and antenna mounting. They provide durability, strength, and corrosion resistance, ensuring the longevity and reliability of the infrastructure. Additionally, steel pipes allow for easy installation and maintenance of telecommunications equipment, making them an essential component in the industry.
- Q: How are steel pipes used in sewage systems?
- Steel pipes are commonly used in sewage systems for their strength, durability, and resistance to corrosion. These pipes are used to transport sewage and wastewater from homes, businesses, and industrial facilities to treatment plants or disposal sites. They are ideal for underground installations due to their ability to withstand high pressure and the weight of the surrounding soil. Additionally, steel pipes can be welded together, providing a seamless and leak-proof system that ensures the safe and efficient transportation of sewage.
- Q: Are steel pipes resistant to impact or external forces?
- Yes, steel pipes are generally resistant to impact and external forces. Steel is known for its high strength and durability, making it an ideal material for various applications, including pipes. Steel pipes have the ability to withstand external forces such as impact, pressure, and vibrations. They are often used in industries that require reliable and sturdy piping systems, such as oil and gas, construction, and infrastructure. Additionally, steel pipes are less prone to cracking or breaking under extreme conditions compared to other materials. However, the resistance to impact and external forces may also depend on the specific grade and thickness of the steel used in the pipes.
