Casing Steel Pipes

Casing Steel Pipes

Uraltrubprom produces steel casing pipes that meet specifications of GOST 31446.


Casing pipes with SL, LC, BC, OTTM, OTTG types of connection.


D 146,05-323,85 mm, wall thickness from 5,87 to 16,5 mm.


Longitudinal electric-welded round pipe produced according to GOST 31446 is used as initial pipe for casing pipes.


Pipe of round section is produced only from coiled steel and its weld is made by induction welding with HFC (high-frequency currents), type 1.


Couplings are produced and coated according to GOST 31446.

 

Main characteristics:

  • Plain or threaded ends
  • Local heat treatment of the weld
  • Casing pipes with plain ends are supplied with anti-corrosion protection or in uncoated condition. The kind of delivery should be chosen by the customer.
  • Casing pipes with threaded ends are delivered with screwed-on couplings and protectors, with anti-corrosion protection.
  • Couplings are of the same type and the same level PSL (PSL-1) as the casing pipes.
  • Kinds of pipe end processing:
    • P — without a thread;
    • SC – short triangular thread;
    • LC - long triangular thread;
    • BC - buttress thread;
    • ОТТМ - trapezoidal thread;
    • ОTTG - trapezoidal thread with "metal-metal" packing assembly.
 
 

Delivery, shipping, order.

  • Pipes are shipped with motor and railway transport. Self-delivery is possible.
  • Pipes are produced under specific order.
  • We accept only wholesale orders from 20 tons (one item or combined order).
