It is a special component of trunk transportation in the unified transportation network, so the transmission pipeline is one of the indispensable equipment in the oil transmission line.

[0003] However, the current pipelines still have some shortcomings. For example, the existing pipelines have poor anti-freeze and anti-cracking effects, which makes the pipelines very prone to freezing and cracking when used in winter or cold areas, which can easily interfere with the subsequent oil transportation and increase the maintenance costs of the staff, resulting in certain usage defects.
