Relevance

The oil refining industry is invaluable for the development of the industrial complex of each state. That is why the normative documentation, regulating the main provisions of production and standard sizes of drilling and tubing parts, is constantly revised and finalized. The tubing transports the extracted "black gold" from the productive zone to the surface of the earth.

Installation

This pipeline is made up of a number of disparate elements by means of threaded connections. At the production stage, therefore, special importance is attached not only to the size and mechanical properties of the tubing, but also to its threaded parts. As a rule, a drill pipe has threaded sections on both of its ends. A special connection sleeve may be screwed onto one end of the product at the factory. At the wellhead of the drilled well, a gushing fitting is attached, with the help of which the string itself, formed of such pipes, is reliably fixed. Submersible pumps are connected to the bottom of the entire structure.

Production Standards

The main normative document governing the production of these products is the state standard No. 633-80, but the enterprise in agreement with the consumer may apply and other technical documentation, both domestic and foreign origin. When manufacturing tubing it is important to ensure strict adherence to norms of technological process and control of each production stage. After rolling and finishing, each pipe is subjected to non-destructive testing. Today there are many variants of this type of tubular products available. The most common variants are: pipes resistant to low temperatures, products with increased tightness of joints, products with individual marking of couplings. According to the type of performance of such a pipe can have as a drop-out ends, and a standard profile or polymer sealing assemblies.

Reliable operation and durability of tubing string directly depends on high-quality manufacturing and proper operation of each structural element. When selecting tubing it is necessary to take into account specifics of its operation and peculiarities of climatic conditions.

It should be noted that all pipes of this type should be marked or branded. And the tightness of the column is provided by the presence on the product protective safety threads, treated with a special resin with high anti-corrosion characteristics.
