Connection of drill pipes

Connection of drill pipes

Are you interested in the characteristics of the drill pipe joints from the supplier Avek Glob? We guarantee high quality products and a large selection of rolled metal products with worldwide delivery.

general information

In practice, composite drill pipes are often used. Pipe connections usually have a length of about 9 m with a threaded connection at each end. The specification of the tubular material, the geometry of the pipe, and the construction of the connecting thread are selected in accordance with the conditions of the formation fluid and the well.

Drill pipes with welded couplings are installed in the drill string and connected to the top cover of the kelling, as well as to the drill string and the drill bit or tool at the bottom.

Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a diverse range of drill pipe connections that meet all technical requirements. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Requirements for drill pipe connections

Regulated by the provisions and norms of TU 1324−137−0147016−01. This specification covers seamless steel pipes with broken ends and welded joints of tools.

Drill pipes with welded couplings are installed in the drill string and connected to the top cover of the kelling, as well as to the drill string and the drill bit or tool at the bottom.

The use of compound drill pipes

Pipes should be used to drill oil, gas and test wells, overhaul and emergency maintenance in appropriate casing strings.

The climatic zone of the use of composite drill pipes from I1 to II12 according to GOST 16350. The alloys of the tool for welding pipes are supplied in accordance with TU 3663−128−01470016−00.

Pipes integrated into the tool are considered repairable. The indicated service life (initial service life) of the tool joints is not less than 1200 cycles of screw-unscrewing.

Dimensions of drill pipes with welded joints of tools and threads with the connecting elements comply with the API standard, Spec. 7, which allows expanding the range of drill pipes not covered by GOST R 50278−92.

Pipes have the optimum values of the ratio of the torques of the tool joint and the pipe, they also have optimal moments of resistance of the body and pin, and tensile deformations of the tool joint and the pipe.

In the design of the pipe, the optimum values of the end-of-pipe tipping coefficients are always selected, which leads to good pipe characteristics with respect to reduced pipe weight.

Supplier — AvekGlob Company — offers to purchase joints to drill pipes in the assortment that meet the technical requirements. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
