Inspection

Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:

Dimensions
Weights
Straightness
Lengths

Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.

Q: What are the different types of supports used for aboveground steel pipes?: There are several types of supports commonly used for aboveground steel pipes, including pipe hangers, pipe clamps, pipe saddles, and pipe shoes. These supports are designed to provide stability and prevent excessive movement or vibration of the pipes, ensuring their proper alignment and preventing damage.

Q: How are steel pipes measured and specified?: Steel pipes are measured and specified based on their diameter (nominal pipe size or NPS) and wall thickness (schedule or SCH). The NPS represents the internal diameter of the pipe, while the SCH indicates the thickness of the pipe walls. These measurements are crucial for ensuring proper compatibility and functionality in various applications, such as plumbing, construction, and industrial processes.

Q: Seamless steel tube DN15 specification phi 18*3 what do you mean?: Seamless steel pipe DN15 specification phi 18*3 refers to 3 outer diameter of 18mm B type DN15 seamless steel tube.

Q: Are steel pipes suitable for underground sewage lines?: Yes, steel pipes are suitable for underground sewage lines. They are strong, durable, and resistant to corrosion, making them an excellent choice for sewage systems.

Q: What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?: Where outdoor heating pipes are buried, what steel pipe shall be referenced by the 11.1.2 code for installation of outdoor piping?:This chapter applies to the quality inspection and acceptance of the outdoor heating pipe network installation of the plant and the civil building group (residential area) with the saturation steam pressure not greater than 0.7MPa, and the hot water temperature not exceeding 130 degrees celsius.

Q: How are steel pipes used in the construction of hydroelectric power plants?: Steel pipes are used in the construction of hydroelectric power plants for various purposes, such as transporting water, containing and directing the flow of water, and supporting the weight of turbines and other equipment. They are typically used for penstocks, which are large pipes that carry water from the dam to the turbines, and for discharge pipes that release water back into the river. The strength and durability of steel pipes make them ideal for withstanding the high pressure and heavy loads involved in hydroelectric power generation.

Q: How are steel pipes protected during transportation?: To ensure the safety and integrity of steel pipes during transportation, various measures are taken. One effective approach involves applying protective coatings to the pipes' exteriors. These coatings, such as epoxy or polyethylene, act as barriers against moisture, corrosion, and physical damage. Additionally, bundling the pipes together and securing them with strapping or bands prevents movement and potential collisions while in transit. To provide extra protection against impact and handling, wooden crates or containers may also be used. Furthermore, careful loading and unloading procedures are followed to minimize stress or strain on the pipes. By implementing these protective measures, steel pipes can safely reach their destination without compromising their quality or structural integrity.

Q: What are the common methods for inspecting the integrity of steel pipes?: Common methods for inspecting the integrity of steel pipes include visual inspection, ultrasonic testing, magnetic particle testing, radiographic testing, and pressure testing.

Q: Can steel pipes be bent or shaped?: Yes, steel pipes can be bent or shaped using various methods such as cold bending, hot bending, or using hydraulic or mechanical equipment.

Q: How do steel pipes handle chemical substances?: Steel pipes are highly resistant to chemical substances due to their high strength and corrosion-resistant properties. They can safely handle a wide range of chemical substances without undergoing any significant degradation or damage.
