Product Overview
The Coiled Tubing Surface Hanger wellhead coiled tubing long-term suspension assembly is a special wellhead fixture developed for permanent long-term hanging of coiled tubing string at the well surface, widely applicable to velocity string installation, gas lift production string running and casing inner wall patch repair remedial workover operations.
This surface hanger supports full live well under-pressure construction operation, the overall on-site rig-up and disassembly workflow is simple and fast, effectively shortening on-site operation cycle. The side outlet connecting flange configuration is fully customizable for users, with three optional standard structural forms: three-way integral connecting flange, threaded stud connecting flange, or fully no side outlet flange design. All standard specifications adopt PSL3 product specification grade, with wide working pressure range covering 5000 psi to 15000 psi, matching coiled tubing outer diameter size of 1.25 inch to 2 inch, standard upper/lower wellhead connecting flange size range 2 9/16" to 4 1/16". Customized raw material grade, high-low temperature resistance index and higher pressure resistance grade can be provided upon customer special construction environment requirements.
The Coiled Tubing Surface Hanger has no complex internal movable friction components, spring energy storage assemblies or differential pressure release mechanisms, with extremely simplified wellsite operation flow and low maintenance cost; construction crews only need to fix the surface hanger on the wellhead upper connecting flange, hang the coiled tubing string into the hanger inner cavity to complete stable long-term suspension locking, and carry out subsequent gas lift string, velocity string or casing patch construction work under live well pressure, no additional complex auxiliary operation steps such as drop ball delivery or shear pin impact jarring are needed, shortening wellsite operation time and reducing human error risks.
The standardized product lineup covers matching coiled tubing outer diameter size of 1.25" to 2", with complete supporting wellhead upper/lower flange size series and multiple side outlet flange configuration options to match different wellhead pipeline connection matching demands and various coiled tubing gas lift string & casing patch remedial workover construction demands. All standard specifications adopt PSL3 product specification grade; custom outer diameter matching size, side outlet flange structural form, raw material grade, temperature resistance index and pressure resistance grade customization are available upon customer technical drawing submission.
