API 5L line pipe, no matter seamless steel pipe or welded type, is now mainly used for conveying gas, water, and oil in the natural gas and oil industries. And thus we need to face some troubles for thinking all situations. High complexity would be one of them.
Oil and gas pipelines have features of long kilometers transport, complex terrain like climbing high mountains and crossing rivers, even passing through the marshes or dessert. Under this situation, we need to guarantee the long transmit for pipelines once we connect the tube with urban and rural construction. So we should produce the steel pipes which can adopt the situation of addressing a large number of temporary problems, such as supplies, transportation vehicles, roads, water, electricity, communications, construction, pipe prefabrication plant and livelihood security, all of which make the pipeline project is more complex.
