Tubing Heads

The Tubing Head is the top spool on a surface wellhead. It is typically installed over the last string of pipe suspended in the well, the production casing. These heads come in a wider range of types and sizes than any other head in a conventional wellhead system. The Tubing Head will provide for well fracturing and allow for the well to be completed using an almost innumerable variety of tubing hangers and tubing head adapters.

• Allows for suspending the production tubing in the wellbore.
• Provides a seal bore for the Tubing Hanger
• Incorporates Lock Down Screws to retain the Tubing Hanger and energize its seals in the seal bore
• Supports the blowout preventers (i.e. ”BOP’s”) while drilling
• Provides outlets for fluid returns
• Provides a means to test the blowout preventers while drilling
• Has flanges on both the top and bottom of the assembly
• Has a seal area in the bottom flange for a secondary seal between the casing annulus and the flanged connection
• Utilize a test port in the bottom flange that allows for the secondary seal and the flanged connection to be pressure tested

TCM–ET Tubing Heads

The TCM-ET tubing head is one of the most widely used tubing head designs in the wellhead industry. It incorporates a straight bowl design and can accommodate almost any TC tubing hanger that does not require an alignment pin. This includes the TC-1W Wrap-around pack-off used on BO-2 and BO-10 coupling type completions.

• The TCM-ET tubing head utilizes ”ET”style Lock Down Screws (LDS) in the upper flange to retain a tubing hanger or tubing wraparound pack-off
• It does not utilize any alignment pins
• It is available with either threaded or studded outlets
• The TCM-ET tubing head has a secondary seal area in the lower flange
• It has a test port in the lower flange to test the secondary seals and the flanged connection

TC-ET Tubing Heads

Yancheng Cyber’s TC-ET Tubing Head has the same features as the TCM but adds a single alignment pin to the bowl area. This pin provides an orientation point in the head for tubing hangers that have alignment requirements.

• The TC-ET tubing head incorporates a straight bowl design
• It utilizes Lock Down Screws (LDS) in the upper flange to retain a tubing hanger
• It is flanged top and bottom
• Has outlets for access to the annulus
• The TC-ET Tubing Head has a secondary seal area in the lower flange
• It has a test port in the lower flange to test the secondary seals and the flanged connection

TC-60-ET Tubing Heads

Yancheng Cyber’s TC-60-ET Tubing Head has the same features as the TC but adds two additional alignment pins to the head. These larger alignment pins are located below the bowl area and allow for dual tubing hangers that are split into separate halves, to be run separately, aligned and landed in the bowl of the TC-60-ET tubing head.

• The TC-60-ET tubing head design can accommodate any TC style tubing hanger
• It utilizes Lock Down Screws (LDS) in the upper flange to retain a tubing hanger
• The TC-60-ET Tubing Head has a secondary seal area in the lower flange
• It has a test port in the lower flange to test the secondary seals and the flanged connection
