L360M Material Performance
L360M is a high-strength pipeline steel grade corresponding to the X52 strength level, with a minimum yield strength of 360 MPa and tensile strength in the 460–600 MPa range according to the applicable specification. Its thermomechanically controlled delivery condition provides a refined balance of strength, toughness, and weldability, making it suitable for demanding transmission and energy infrastructure. Huayang manufactures L360M LSAW pipe through plate forming and double-sided submerged arc welding. The company's LSAW capability covers large diameters and wall thicknesses up to 50 mm, while inspection can include 100% ultrasonic testing, radiographic weld examination, hydrostatic testing, dimensional inspection, and mechanical testing according to project requirements.

Pipe Protection
Pipe-end protection is advisable in case the pipe-ends are bevelled at the pipe manufacturer. In the case of overseas transport, there is an especially increased risk of damaged pipe-ends. This is caused by extra handling procedures in ports and shifting of the pipes onboard vessels.
In addition to end caps or protective rings, external wrapping with protective cloth can be applied along the pipe body. This wrapping helps to safeguard the coating surface from scratches, moisture, and contamination during long-distance transportation or prolonged outdoor storage. Especially for coated or painted pipes, the additional protective cloth layer significantly reduces the risk of mechanical damage, UV exposure, and corrosion initiation, ensuring the pipes arrive at the destination in optimal condition.
