Product  Descriptions :N80 Perforated Casing Pipe

1.The Perforated pipe uses J55 or N80 oil casing as the processing body. This ensures high strength and no distortion.
2.The hole is uniform,smooth,and has no burr.
3.The overall anticorrosive processing results in a dense protective layer on the surface of screen pipe,so as to improve its corrosion and wear resistance,and effectively prolong the downhole working life.
4.The perforated pipe comes with simple use. due to big inside diameter,it also brings convenience for pipe string sonfiguration.
5.The type of hole can be freely selected by the customer.

Q: How do you select the right size of steel pipe for a project?
To select the right size of steel pipe for a project, it is important to consider factors such as the desired flow rate, pressure requirements, fluid type, and the overall structural design. Consulting relevant design codes and standards, performing calculations based on these parameters, and seeking expert advice can help ensure the appropriate size is chosen to meet the project's specific needs.
Q: What are the common applications of steel pipes in construction?
Steel pipes are commonly used in construction for various applications such as structural support, plumbing, water distribution, gas transportation, and HVAC systems. They provide strength, durability, and resistance to corrosion, making them an ideal choice for these purposes.
Q: Can steel pipes be used for irrigation pivot systems?
Yes, steel pipes can be used for irrigation pivot systems. They are often preferred due to their durability, strength, and resistance to corrosion. Steel pipes can efficiently transport water over long distances, making them suitable for irrigation pivot systems that require reliable water supply.
Q: What are the applications of galvanized steel pipes?
Galvanized steel pipes have a wide range of applications across various industries. They are commonly used in plumbing systems for water supply and drainage systems due to their corrosion resistance and durability. Additionally, they are used in the construction industry for structural supports, scaffolding, and fencing. Galvanized steel pipes are also widely utilized in agricultural irrigation systems and in the transportation of liquids and gases.
Q: How do steel pipes perform in earthquake-prone regions?
Steel pipes perform well in earthquake-prone regions due to their high strength and ductility. They are capable of flexing and absorbing seismic energy, reducing the risk of catastrophic failure. Additionally, steel pipes can be designed with proper reinforcement to withstand ground movements, making them a reliable choice for infrastructure in earthquake-prone areas.
Q: How are steel pipes tested for pressure and leakage?
Steel pipes are tested for pressure and leakage using a variety of methods to ensure their safety and reliability. One common method is hydrostatic testing, where the pipe is filled with water and subjected to a specific pressure for a specified duration. This test helps identify any weaknesses or leaks in the pipe by observing if there is any pressure drop or visible water leakage. The pressure is carefully measured and monitored during the test, and if the pipe successfully withstands the required pressure without any signs of leakage, it is considered to have passed the test. In addition to hydrostatic testing, other non-destructive testing methods may also be employed. These methods include ultrasonic testing, which uses high-frequency sound waves to detect any flaws or defects in the pipe material, and magnetic particle testing, which involves applying a magnetic field to the pipe and inspecting it for any magnetic particles that may indicate cracks or imperfections. Moreover, visual inspection is an essential step in testing steel pipes for pressure and leakage. Trained inspectors examine the exterior and interior surfaces of the pipe to check for any visible signs of damage, such as corrosion, cracks, or faulty welds. This visual inspection helps to identify potential weak points that could lead to leaks or failures under pressure. Overall, a combination of hydrostatic testing, non-destructive testing methods, and visual inspection is used to comprehensively evaluate steel pipes for pressure and leakage. These rigorous testing procedures ensure that the pipes meet the required standards and are safe for their intended applications.
Q: How can galvanized steel pipe be connected with stainless steel pipe?
The method of non direct fusion is adopted, such as blue, silk head and movable joint
Q: How are steel pipes used in construction?
Steel pipes are commonly used in construction for various purposes such as structural supports, plumbing systems, and underground utility installations. They provide strength, durability, and flexibility, making them suitable for carrying fluids, gases, and structural loads. Steel pipes are often used in the construction of buildings, bridges, and infrastructure projects, ensuring reliable and long-lasting performance.
Q: Can stainless steel pipes spray black paint?
Can. The surface roughening with a thick gauze, do not use ordinary paint intensity difference. With resin paint, paint can be
Q: How do you calculate the pipe friction loss coefficient for steel pipes?
The pipe friction loss coefficient for steel pipes can be calculated using the Darcy-Weisbach equation, which takes into account the pipe diameter, length, roughness, and fluid velocity. The coefficient can be determined by dividing the friction factor (obtained from Moody's chart or using empirical equations) by the Reynolds number (calculated using the fluid properties and pipe dimensions).
