Design features

He drill pipes are connected with locks into the drill column, which creates a special axial load on the rock-cutting tool and delivers the torque to it, and also serves to feed the drill solution or compressed air to the well face.

During drilling, the drill pipes subject to significant loads that is why they are manufactured by means of seamless hot or cold rolling out of all high hardness carbon and alloyed steel grades. The pipe ends, which subject to maximal loads are manufactured, thickened with outer, internal or combined upset (when manufacturing from solid work piece with further mechanical and thermal processing). The ends of the articles of assembled design are equipped with thickened transmitters.

Classification of the drill pipes

According to their designation, the following drill pipes are defined: kelly bars, ordinary drill pipes and drill collars. The latter differ with bigger weight and increased strength (thanks to their increased wall thickness) and they are considered to create the additional load on the tool. The kelly bar has a square or multi-plane section to deliver the torch from the drill rig drive. According to the way of connection, the following drill pipes can be distinguished:

  • The drill pipes with ring tool joint by means of transition elements(couplings and locks with conic thread) – it is the most universal version;
  • The drill pipes with nipple joint. They are mainly used in exploratory core drilling for pipes with diameter up to 60 mm.;
  • The drill pipes with welded locks. The lock connections on the ends are not detachable, and this allows getting the smooth column outside.

The drill pipes with welded locks: specifications and technical features

The welding of nipple and couplings to the upset ends of the drill pipe allows combining the advantages of the ring tool and nipple joint. In this case, the factory labor hours increase and the requirements to the control of technological operations are higher. CJSC «Mining technologies» manufacture the customized articles of any complexity according to the drawings submitted by the customer, which meet the requirements of the domestic and foreign regulative documents, including:

  • GOST R 50278-92;
  • GOST 27834-95;
  • GOST R 51245-99;
  • API Spec 5D specifications;
  • API Spec 7 specifications.
  • API (American Petroleum Institute)- one of the leading standard developers in the sphere of equipment for oil and gas extraction.

Advantages of drill pipes with welded locks

The surface hardening with high-frequency currents (HFC) contributes to reduction of drill pipe wear during drilling and keeping straightness during the whole period of operation.

By means of carbonitriding the increased wear-resistance of the thread joint is achieved, and this prevents possible equipment fault due to the thread wear. The lock details are connected with the pipe body by means of the fraction welding on a special welding machine. Due to this drilling technology, the high alignment of lock and pipe is achieved. The ideal column balancing allows executing the drilling with a higher speed and less power consumption. The smooth housing and balance of the drill column significantly reduces the destruction of well walls. The column wear along the pipe and lock body occurs more evenly.

Payment and delivery

The payment is execute by means of the funds transfer to the settlement account. We conclude the contract for manufacture and delivery, where we establish the term of the batch manufacture, and the delivery way. After that, the invoice is issued, according to which the customer pays for the order. After the monetary funds reach the settlement account, the production is launched and the batch of the products is manufactured, which is shipped to the customer through the forwarder.

The approximate term of manufacture — 30 days, the exact term is defined by the scope and complexity of the order manufacture.

The order is delivered in a sea container. The delivery term is established by the forwarder.
