X52 pipeline steel pipe is a common steel pipe material, often used in oil and gas pipelines, hydropower station water pipelines and other fields. Its performance characteristics mainly include the following aspects:
1. Physical properties:
The physical properties of X52 pipeline steel pipe mainly include the following aspects:
Hardness: The hardness of X52 pipeline steel pipe is relatively high, usually 120-135HBW in the Brinell hardness range.
Strength: The tensile strength of X52 pipeline steel pipe is between 360-530Mpa, which belongs to the medium-strength steel species.
Toughness: As a transmission pipeline, X52 pipeline steel pipe must have good toughness, and can quickly recover to its original state when subjected to a certain external force impact, so as to achieve the purpose of long-lasting durability.
2. Chemical composition:
The chemical composition of X52 pipeline steel pipe mainly includes carbon (C), silicon (Si), manganese (Mn), chromium (Cr) and other elements, among which the carbon content is between 0.16%-0.22%, the manganese content is between 1.4%-1.9%, the silicon content is below 0.5%, and the chromium content is about 0.5%.
3. Fatigue resistance:
X52 thick-walled spiral steel pipe has good fatigue resistance and can remain stable under frequent stress cycles.
4. Corrosion resistance:
In actual applications, X52 pipeline steel pipes are often exposed to corrosion from chemical substances, so good corrosion resistance is one of its necessary characteristics. X52 pipeline steel pipes are usually treated with coating materials such as passivation to enhance their corrosion resistance.
