Tubing Head Spools with Two Control Lines and ESP Penetrator

• Seals in bothdirections
• The pre-loading activates the sealing mechanism
• It seals at small loading Loading
• 50 % of pipe body’s yield strength
• Can be designedfor greater loading ifrequired
• Loading depends on the toughness and the thickness of the casing

• Seals in bothdirections
• The pre-loading activates the sealing mechanism
• It seals at small loading Loading
• 70 % of pipe body’s yield strength

• Seals in bothdirections
• Sealing is replaceable with load on hanger

• Used for casings cemented up to surface
• Lifting thread: casing thread
• Bottom thread: casing thread

• Assembly time is essentially shorter than in case of slip type hangers

In general all tubing hangers can be manufactured
• With upper thread from 2 3/8" to 4 ½" NV/EU/TB and
•  lower thread from 2 3/8" to 4 ½" NV/EU/TB
• Eith BPV 2" - 4" H type

Several main types are manufactured by Csepel Techno Ltd.

Wear Bushing Combined Tool

The same tool can be used for mounting wear bushings and can beused as a test plug for the BOP as well

• Size: from 5 ½” up to 13 3/8”

• Size: from 5 ½” up to 13 3/8”

A slip type casing hanger can be seated in the place of the mandrel casing hanger (using an adapter bushing)

- the different hangers can be replaced within short time in the same wellhead
