The oil-pipe from Lanzhou to Chongqing is the only pipe that transports product oil to the Western areas.

Based on the construction acceptance norms and the actual construction conditions of the product oil transmission pipeline, the paper introduced the key of supervision in the scope, inspection standards, inspection method and sampling ratio for three main sections of welding, repairing and mending, pipe tunnel digging and backfilling under the pipeline.

Numerical modeling of oil pipeline bending caused by migrating pingos in the permafrost on the northern Qinghai-Tibet Plateau;

A new method of synchronized design for oil pipeline and thermal insulation layer;

Design and implementation of the oil pipelines leak detection system based on wireless local area network;

The concept of synchronous design for oil transmission pipeline and its insulating layer is put forward from the angle of total expenses.
