Q:What is the difference between steel pipes and polyethylene pipes?: Steel pipes are made of a strong and durable material, steel, which makes them suitable for high-pressure and high-temperature applications. They are also resistant to corrosion, making them ideal for transporting liquids and gases. On the other hand, polyethylene pipes are made of a flexible plastic material, which makes them easier to install and handle. They are lightweight, resistant to chemicals, and have a low risk of corrosion. However, they may not be suitable for very high-pressure or high-temperature applications.

Q:How are steel pipes used in oil refineries?: Steel pipes are extensively used in oil refineries for various purposes such as transporting crude oil, refined products, and gases throughout the facility. They are used in the construction of pipelines, process equipment, and storage tanks, providing a reliable and durable solution for handling the vast quantities of liquids and gases involved in the refining process.

Q:Are steel pipes suitable for underground gas distribution?: Yes, steel pipes are suitable for underground gas distribution. Steel pipes are widely used in gas distribution systems due to their high strength, durability, and resistance to corrosion. They are able to withstand the pressure and stress of underground conditions, making them a reliable choice for transporting gas. Additionally, steel pipes have the advantage of being able to handle high temperatures and are resistant to fire, making them a safe option for underground gas distribution. However, it is important to ensure that the steel pipes used are properly coated and protected against corrosion to ensure their longevity and prevent any potential leaks or damage.

Q:How are steel pipes protected against abrasive wear?: Steel pipes are protected against abrasive wear through various methods such as applying protective coatings, using abrasion-resistant liners, and implementing proper maintenance and monitoring practices.

Q:What is the standard length of a steel pipe?: The standard length of a steel pipe can vary depending on the application and industry, but commonly it ranges from 18 to 24 feet.

Q:What are the different methods of threading steel pipes?: There are several methods of threading steel pipes, including manual threading, machine threading, and cutting threads using a thread cutting die. Manual threading involves using a handheld pipe threading tool to create threads on the pipe. Machine threading utilizes a power-driven pipe threading machine to efficiently create threads. Cutting threads using a thread cutting die involves using a die and a handle to manually cut threads on the pipe. These methods are commonly used in various applications, such as plumbing, construction, and industrial settings.

Q:What is PE coated steel pipe? Seek explanation: PE coating on the inner wall of steel pipe steel pipe is covered with a layer of polyethylene plastic polymer, PE, polyethylene (Polyethylene of raised temperature is the abbreviation of resistance English), the scope of application of the general PE pipe water supply pipe to a temperature below 40 DEG C, cannot be used for hot water transmission pipeline.

Q:What are the different types of flanges used with steel pipes?: There are several types of flanges that are commonly used with steel pipes, including slip-on flanges, weld neck flanges, threaded flanges, socket weld flanges, lap joint flanges, and blind flanges. Each type has its own unique design and application, and they are used to connect and secure steel pipes together in various industrial and construction settings.
