A: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q: How do you join two steel pipes together without welding?: One way to join two steel pipes together without welding is by using threaded connections. This involves screwing a threaded fitting onto each end of the pipes, creating a secure and durable connection. Additionally, other methods such as mechanical couplings or flanges can also be used to join steel pipes without welding. These methods provide a reliable and convenient alternative to welding for joining steel pipes together.

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: What is the meaning of "DN" and "Phi" in the dimensioning of steel pipe diameter and how to apply the mark?: DN represents the path of the tube". Fair represents diameter. Path is the diameter of the fluid through which it should be inside. The diameter may be the outer diameter or the inner diameter. The diameter is only used when the pipe is used for flow through. Fair as long as the garden can be used. According to the requirements of mechanical drawing fair, DN text notes.

Q: How are steel pipes protected against external damage?: Steel pipes are protected against external damage through various methods such as anti-corrosion coatings, insulation materials, and cathodic protection systems. These measures help prevent corrosion, impact, and abrasion, ensuring the durability and longevity of the pipes.

Q: What's the difference between steel pipe and pipe fittings?: Pipe fittings: parts that connect pipes to pipes. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange pipe fittings and welding pipe fittings four kinds. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.

Q: What are the different methods of welding steel pipes?: There are several methods of welding steel pipes, including arc welding, TIG (tungsten inert gas) welding, MIG (metal inert gas) welding, and oxy-fuel welding. Each method has its own advantages and applications, depending on factors such as the thickness of the steel, the desired strength of the weld, and the available equipment.

Q: Can steel pipes be used for conveying gases?: Yes, steel pipes can be used for conveying gases. Steel pipes are widely used in industrial applications for transporting various gases, including natural gas, propane, and other types of gases. Steel pipes have excellent strength and durability, making them suitable for carrying gases at high pressures and temperatures. Additionally, steel pipes have a high resistance to corrosion, which is crucial when dealing with gases that can be corrosive.

Q: How are steel pipes marked for identification?: Pipe marking is a process used to identify steel pipes. This process involves placing labels or markers on the pipes' surface to provide important information about their specifications and characteristics. The labels typically include details such as the size, grade, material composition, manufacturer's logo or name, and any relevant codes or standards. These markings are crucial for proper identification and ensure that the right pipes are used for specific applications, as well as for maintenance and repair purposes. Furthermore, the markings also assist with quality control and traceability, making it easy to identify and track the pipes throughout their lifespan. In summary, using clear and durable marking systems to identify steel pipes is vital for safety, efficiency, and compliance in various industries where these pipes are used.

Q: How are steel pipes protected against fire?: Steel pipes are typically protected against fire through the application of fire-resistant coatings or by encasing them in fire-rated materials, such as concrete or gypsum board. Additionally, fire sprinkler systems or fire-resistant insulation may be installed around the pipes to provide an added layer of protection.

Q: Are steel pipes suitable for high-pressure applications?: Yes, steel pipes are suitable for high-pressure applications. Steel pipes are known for their strength and durability, making them ideal for handling high-pressure applications. They can withstand the internal pressure exerted by fluids or gases under high pressure without deforming or bursting. The high tensile strength of steel allows it to resist the forces that occur in high-pressure environments, ensuring the safety and reliability of the piping system. Additionally, steel pipes can be manufactured with thicker walls to further enhance their ability to withstand high pressures. Steel pipes are widely used in industries such as oil and gas, petrochemical, power generation, and water distribution, where high-pressure applications are common.
