- Q: DN80 seamless steel tube, what is the standard thickness?
- Generally speaking, the diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter. Tubes are made of seamless steel tubes. The outer diameter of the tubes is indicated by the letter D, followed by additional outer diameter dimensions and wall thicknesses such as seamless steel tubes with an outer diameter of 108.
- Q: What is the weight and strength of steel pipes?
- The weight and strength of steel pipes differ based on their dimensions and the specific steel grade utilized. Typically, the weight of steel pipes is measured in pounds per foot or kilograms per meter. The strength of steel pipes is commonly evaluated in terms of yield strength and ultimate tensile strength. The weight of steel pipes can range from a few pounds per foot for smaller sizes to several hundred pounds per foot for larger diameters and thicker walls. Various factors, including the pipe's outer diameter, wall thickness, and length, impact the weight. For example, a 1-inch diameter steel pipe with a wall thickness of 0.125 inches may weigh approximately 0.67 pounds per foot. Conversely, a 12-inch diameter steel pipe with a wall thickness of 0.5 inches can weigh roughly 142 pounds per foot. The strength of steel pipes is determined by the grade of steel used, which can vary depending on the specific application and requirements. Commonly used steel grades for pipes include ASTM A53 for general purposes, ASTM A106 for high-temperature service, and API 5L for oil and gas transportation. These grades possess different yield strengths and ultimate tensile strengths. Yield strength denotes the amount of stress a steel pipe can endure before it starts to deform plastically. It is usually measured in pounds per square inch (psi) or megapascals (MPa). For instance, ASTM A53 Grade B steel pipe has a minimum yield strength of 35,000 psi (240 MPa), while API 5L Grade X65 steel pipe has a minimum yield strength of 65,000 psi (448 MPa). On the other hand, ultimate tensile strength signifies the maximum stress a steel pipe can withstand before fracturing. It is also measured in psi or MPa. For example, ASTM A106 Grade B steel pipe has an ultimate tensile strength of 60,000 psi (415 MPa), whereas API 5L Grade X65 steel pipe has an ultimate tensile strength of 77,000 psi (531 MPa). In conclusion, the weight and strength of steel pipes can vary based on their dimensions and the grade of steel used. The weight is influenced by factors like the pipe's diameter, wall thickness, and length, while the strength is determined by the steel's yield strength and ultimate tensile strength.

The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)
- Q: What is the difference between internal lining and external coating of steel pipes?
- The difference between internal lining and external coating of steel pipes lies in their respective purposes and locations. Internal lining refers to the material applied inside the steel pipes to protect the inner surface from corrosion, abrasion, or other forms of damage. It acts as a barrier between the transported fluids or substances and the steel pipe, preventing them from coming into direct contact and causing deterioration. The internal lining is typically made of materials like epoxy, polyethylene, or cement mortar, depending on the specific requirements and the nature of the transported substances. It ensures the longevity and integrity of the steel pipe by reducing the chances of internal corrosion and minimizing the risk of contamination. External coating, on the other hand, is applied to the outer surface of the steel pipes. Its main purpose is to provide protection against external factors such as weathering, soil corrosion, and mechanical damage. The external coating acts as a shield, safeguarding the steel pipe from environmental conditions like moisture, UV radiation, chemicals, and physical impact. Common materials used for external coatings include fusion-bonded epoxy, polyethylene, polypropylene, or bitumen. The choice of coating depends on factors like the exposure conditions, temperature, and the type of soil or surroundings the steel pipe will encounter. In summary, while internal lining protects the inner surface of steel pipes from corrosion and damage caused by transported substances, external coating acts as a barrier against external elements and physical stresses. Both internal lining and external coating play vital roles in ensuring the durability and reliability of steel pipes in various applications, such as oil and gas pipelines, water supply systems, or industrial processes.
