Selecting the diameter and calculating the weight of the drill string

Tubing is used in industry to transport gas and liquid inside casing strings during the operation of gas and oil wells. They also find application in various types of hoisting and repair work.

These pipes are connected to each other by couplings with a threaded connection. These connections allow you to maintain the patency of the pipe in curved and places with a complex profile. They also maintain tightness at the joints and the ability to be easily replaced and repaired.

The plants of Pipe Metallurgical Company have adopted the ISO 9001-2000 quality system; API Q1 in accordance with post-operative control, and meets the following requirements: API Spec 5CT, Spec 5B; GOST 633-80 and consumer technical conditions. This system allows you to trace 100% quality of tubing pipes and their parts.

All pipes and couplings undergo non-destructive testing. The most modern technologies are used in their production. The pipes undergo appropriate quality control, also using modern methods.

Pipes are manufactured in accordance with the following range:

  • cold-resistant;
  • highly sealed;
  • corrosion resistant;
  • with a sealing unit made of polymer material;
  • with ends set outward;
  • with distinctive coupling markings;
  • standard version.

At the customer's request, they can be metal, polymer or a combination.

The pipes are marked and branded in accordance with current requirements. These products are supplied with threaded connections protected with a special grease, which extends the life of the pipes.

Computer program GEOFPRO Fluid

Calculation of well hydraulics

The computer program will calculate the pressure loss due to friction in the drilling fluid over the well intervals, calculate the EDS, and the wellbore cleaning index:

— inside sections of drill pipes and BHAs,

— between the walls of the well and the drilling tool,

— between the string of casing and drill pipes.

The hydraulic calculation of the well is presented in the form of a graphic report, with clear and simple diagrams and graphs.

On our website you can download a FREE computer program - a calculator for calculating the mass and weight of casing and drill pipes, tubing tubing.

Specifications

The pipe can be welded or seamless. In the first case, for the production of rolled metal, sheet steel and strips are used, which are joined at the joint by welding. The length of the pipe can vary from 1.5 to 20 meters; the material used is different grades of steel, including stainless steel.

Seamless pipes are produced by drawing, pressing, forging or rolling. Such products are characterized by versatility, durability, and wear resistance. Seamless pipe is able to withstand constant heavy loads, therefore it is used in the food, chemical and automotive industries. This assortment comes in thick-walled and thin-walled. The latter is used if high demands are placed on geometry accuracy and quality of material processing.

Pipes can be cold-formed or hot-formed. At the initial stage, the workpiece is heated to a soft state, after which it passes through the press. The required shape is obtained by rolling at the melting temperature of the metal (for hot-deformed), or below it (for cold-deformed). The diameter of the former varies from 20 to 550 mm, the latter – from 5 to 250 mm. The wall thickness also differs - 2.5 - 75 mm, 0.3 - 24 mm.

Depending on the purpose of the pipe, all products are classified into 6 classes: large-diameter pipes are mainly used for the installation of gas pipelines, oil pipelines and the arrangement of protection of utility lines.

  • Class 1 – used as fences, supports, local gas supply systems. Manufactured from high-carbon steel grades.
  • Class 2 – designed to work with high and low pressure, used in supply systems for gas, fuel, and petrochemical products.
  • Class 3 - characterized by resistance to elevated temperatures, they are used in heating boilers, chemical and nuclear industries.
  • Class 4 – pipes for drilling wells, casing, etc.
  • Class 5 - used for the manufacture of supports, masts, structural elements and other equipment.
