The seamless carbon steel pipe for ships (gb5213-85) is the seamless carbon steel pipe for the manufacture of class I pressure pipe system, class II pressure pipe system, boiler and Superheater of ships. S690QL1 steel grades. The working temperature of carbon steel seamless pipe wall shall not exceed 450 ℃, and that of alloy steel seamless pipe wall shall exceed 450 ℃.

15CrMo alloy steel plate is pearlite structure heat-resistant steel, which has high heat strength (δb≥440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in steel, the hardening tendency of steel S690QL1 steel grades is obvious and the weldability is poor. 15crmo alloy steel plate is mainly used in petroleum, petrochemical, high-pressure boilers, etc.

Non-destructive flaw detection of steel plates is a test method for inspecting the S690QL1 steel grades surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used S690QL1 steel grades steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.

The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. S690QL1 steel grades, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability.
