Varieties and requirements for the operation of pipeline fittings for petroleum products

Transportation of hydrocarbons through pipeline systems should be carried out taking into account the specifics of easily flammable liquid and gaseous media. The increased safety requirements can be fully satisfied if all elements of the raw material transfer systems are carried out using only high-quality pipe fittings.

Types of pipe fittings

Pipeline fittings for the oil and gas complex can be of the following varieties:

• Shut–off - provides an overlap of the movement of the medium.
• Regulatory – controls the physical parameters of hydrocarbons transported through the pipeline.
• Safety – stops and starts the movement of the working medium.
• Control – designed to monitor the main parameters of the environment being moved.

Shut-off valves in the form of valves are most often used when organizing the movement of hydrocarbons. Such elements perfectly cope with the task of controlling the flow of liquid and gaseous media, have minimal hydraulic resistance and allow for a high level of sealing.

Requirements for NPC pipe fittings

The following requirements apply to fittings for pipelines through which oil products will be transported:

• The strength of the body and the main parts.
• Corrosion resistance.
• Explosion safety.

Increased requirements are also imposed on the possibility of safe movement of hydrocarbons in conditions of a significant temperature difference.

Ensuring the necessary quality level of pipeline fittings for petroleum products allows not only to make the operation of pipeline systems safe, but also significantly extend the service life of shut-off devices.

Distinctive features of shut-off valves for petroleum products

Some distinctive features of shut-off valves for petroleum products depend on the operating conditions of pipeline systems. For example, if the pressure exceeds 1 MPa, it is recommended to use valves and valves made of steel.

With significant temperature differences, cast iron products should not be used, which can collapse under such an impact.
