Sleeve Boring
Sleeves are boringBoring sleeves are used for pumping of oil on drilling rigs under big pressure. Also they are used as anti - vibration inserts, at workover. Thanks to wear resistance the boring sleeve can be used as a sleeve for betononas.
Boring sleeves of GOST 28618 - 90 (anti - vibration, metalcord) have internal diameters:
Boring sleeve of Du 50;
Boring sleeve of Du 63;
Boring sleeve of Du 89;
Boring sleeve of Du 102.
On the ends of a sleeve are pressured up by unions or flange connection. Sleeves meet nuts on the ends. Such sleeves it is made under the order. The most often used lengths of boring sleeves - 6, 12 and 18 meter pieces. Sometimes use 3 m, 4.5m, 16 m, 22 m, 24 m.
Working pressure upon this type of boring sleeves – 150 atm. , 200 atm. , 250 atm. , 300 atm. , 350 atm. Sleeves have 4 layers of a heavy - duty braid, small weight, the minimum radius of a bend, a large supply of durability (koeffitsent 2,5), temperature condition - minus of 45 degrees to plus 120 degrees Celsius.
Boring sleeves perfectly proved thanks to high wear resistance, big service life, work in adverse climatic conditions.
The Hydraulics Trade company makes sleeves boring:
● 38 mm (1.1/2 inches)
● 76 mm (3 inches)
● 50 mm (2 inches)
● 100 mm
● 150 mm
The complete set various quick disconnect connections is possible:
BRS 2 inches, BRS 4 inches, flanges, naves, etc.
Sleeve boring with a diameter of 38 mm
Sleeves are used both for drilling and for workover.

Sleeve boring with a diameter of 50 mm
The sleeve boring with a diameter of 50 mm can be applied both when drilling, and at workover.
Our company makes a sleeve boring with a diameter of 50 mm with a length up to 40 m in four executions:
Sleeve of boring Ø50 Rrab. = 80 atm (dolivochny sleeve)
Sleeve of boring Ø50 Rrab. = 250 atm (a standard sleeve for KRS)
Sleeve of boring Ø50 of elevated pressure Rrab. = 350 atm
Sleeve of boring Ø50 of elevated pressure Rrab. = 420 atm
