The oil pipeline is a complex engineering and technical design of the pipeline, which is needed to transport oil at huge distances. You can distinguish main and commercial oil pipelines. These are kilometers of ground and underground pipelines that are subjected to corrosion destructive phenomena every second. In the pipeline, any system requires appropriate isolation to ensure the safety of the functioning of the system for a long period. Special communications of the main and industrial purpose is a network of pipes that are always subjected to temperature extremes, pressure, condensate, as well as trivial rust. In order to prevent aging of communications, special isolations are used for pipelines.The insulation of oil pipelines is very important in order to maintain the speed of oil transportation and its final quality, because oil passes hundreds of kilometers of the way. The oil pipeline has high requirements for insulation of communications, which also depends not only on insulating materials, but also on compliance with the technology for their installation. Different materials are aimed at protecting against a certain action on the pipeline: excessive heating, moisture, hypothermia, natural metal corrosion, etc.D.
The insulation of the oil pipeline is bilateral protection. In addition to the protection of oil from the environment, because it is also necessary to protect the environment itself from the harmful effects of chemicals. Under isolation for this purpose, they also understand protection against spontaneous combustion and fires, which means that it should have a constant temperature inside the pipes.
The main requirements are, first of all, the correct choice of suitable materials for isolation of oil pipelines. Materials for insulation should serve as protecting the pipeline from pressure drops, exposure to critical temperatures, always hold the working temperature inside the pipes, withstand the desired mechanical load, prevent the spread and fire of fire, lower the noise level and much more.
Materials necessary for the isolation of oil pipelines. In old gas and oil pipelines, the use of vatine or asbestos fabric is very often found to insulate the pipeline, which are covered with polyethylene or foil for greater tightness. Currently, these materials have ceased to be used because they have low reliability and they are short -lived compared to the current technological coatings.
Polyuertan foam is an inexpensive, easily mounted and durable protection for a metal pipeline. Applying this material, absolute safety for human health is ensured, which is difficult to say about asbestos tissue. This coating has high fire resistance.
Another type of material for isolation is a bitumen mastic, which is used as a good protection against corrosion of metal pipes. This material is based on alternative additives or polymers.
