Q: Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding should be for spot welding and single side welding, they are straight line welds, but double submerged arc welding seam is more beautiful and fine.
Q: What does GALV mean in a steel tube?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q: Can steel pipes be used in the oil and gas industry?
Indeed, the oil and gas industry commonly utilizes steel pipes. Renowned for their robustness, longevity, and resistance to corrosion, steel pipes are well-suited for the transportation and storage of diverse fluids and gases within this sector. They possess the ability to endure high pressure and extreme temperatures, which are frequently encountered during oil and gas operations. Moreover, the ease with which steel pipes can be welded together facilitates efficient assembly and maintenance. Consequently, steel pipes represent a dependable and economically sound option for the oil and gas industry.
Q: What is the single length of galvanized steel pipe?
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned.
Q: How are steel pipes measured?
Steel pipes are typically measured by their outer diameter (OD) and wall thickness. The OD is measured using a caliper or tape measure, while the wall thickness is determined using a specialized instrument called a micrometer. These measurements are crucial in determining the size and strength of steel pipes for various applications.
Q: How are steel pipes tested for quality assurance?
Steel pipes are tested for quality assurance through various methods such as hydrostatic testing, non-destructive testing (NDT) techniques like ultrasonic testing, magnetic particle testing, and visual inspection. These tests ensure that the pipes meet the required standards and specifications, checking for flaws, defects, and proper dimensional accuracy.
Q: Can steel pipes be used for wastewater treatment?
Yes, steel pipes can be used for wastewater treatment. Steel pipes are commonly used in various stages of wastewater treatment processes, such as conveyance, distribution, and collection systems. They are durable, corrosion-resistant, and can withstand high-pressure conditions, making them suitable for transporting wastewater efficiently and safely. Additionally, steel pipes can be coated or lined to enhance their resistance to corrosion and improve their performance in harsh wastewater environments.
Q: The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
That is, according to the production process of different classification, different from hot rolling (expansion) pipe. In the process of expanding the tube or raw material tube, it is processed by multiple cold drawing, usually on single chain or double chain cold drawn machine of 0.5 ~ 100T. Cold rolled steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube, machining pipe, thick wall pipe, small diameter and cold drawn steel tube also includes other tubes, carbon thin-walled steel, alloy thin-walled steel pipe, stainless steel pipe, special-shaped wall steel pipe. The outside diameter of cold drawn steel tube wall thickness to 6mm, to 0.25mm, to 5mm diameter thin-walled tube wall thickness is less than 0.25mm in size, accuracy and surface quality were significantly better than the hot (expanding) tube, but by the process control, its diameter and length are limited.
Q: What are the different types of steel pipe coatings for drinking water pipelines?
The different types of steel pipe coatings for drinking water pipelines include cement mortar lining, polyurethane lining, epoxy lining, and polyethylene wrapping. These coatings are applied to the interior and/or exterior of the pipes to prevent corrosion and ensure the safety and quality of the water being transported.
Q: What is the difference between seamless and welded steel pipes?
The main difference between seamless and welded steel pipes lies in their manufacturing process. Seamless pipes are made by piercing a solid cylindrical steel billet to create a hollow tube without any welding or joints. On the other hand, welded pipes are formed by rolling a flat steel plate and then welding the edges together to create a cylindrical shape. This welding process introduces a seam along the length of the pipe. Consequently, seamless pipes are typically considered stronger, more reliable, and better suited for high-pressure applications, while welded pipes are more cost-effective and commonly used for less demanding applications.
