MOD1_Lecture 3/5: Introduction - Hot tapping Functions3:14
Explore hot tapping functions, including tapping a new branch without shutdown and stoppling for a temporary bypass isolation, using fittings, sandwich valves, and bypass arrangements.
MOD1_Lecture 4/5: Introduction - Hot Tap Fittings5:31
Learn how hot tap fittings enable permanent and temporary branch connections using bolted or welded tees, valves, and tapping machines, with bypass and stopple options, full-branch and reduced-branch split tees.
MOD1_Lecture 5/5: Introduction - Hot tapping Machines , Cutter and Valves4:12
Explore hot tapping machines and cutters, including pilot drills, coupons, and valves. Learn how sizes, stopple cutters, and valve selection affect installation and flow losses.

Lecture 1/4: Hot tap Decision Making3:33
Explore hot tapping decision making using feasibility studies, surveys, and job safety analysis, guided by API 2201, to ensure safe, viable hot taps with proper procedures and permits.
Lecture 2/4: Feasibility Study8:20
Assess feasibility for hot tapping by weighing shutdown vs modification costs, considering welding suitability, materials, process fluids, operating conditions, site access, and safety risks such as burn-through and hydrogen cracking.

Survey run pipe and pipeline locations to plan hot tapping, checking diameter, ovality, thickness, welds, lamination, and corrosion; implement job safety plan and risk assessment.
Lecture 4/4: Job safety Analysis3:05
Conduct a job safety analysis for hot tapping, avoiding dead-end or stagnant systems, atmospheric-pressure sites, and thin-walled or lined pipes, especially when thickness is under 4.8 mm.

MOD3_Lecture 1/7: Codes and Standards4:44
Outline key codes and standards for hot tapping, including CSA Z662, API 1104 Appendix B, ASME IX and ASME B31.3, and explain fitting design, pressure requirements, and in-service welding.
MOD3_Lecture 2/7: Welding Design - Welding Processes and Electrodes3:13
Explain welding design for hot tapping using SMAW and GTAW, buttering layers, and electrode handling with low hydrogen basic coated electrodes, storage, backing, and 120 C bake.
MOD3_Lecture 3/7: Welding Design - Welding Sequence14:44

Description

Hot tapping is the technique of attaching mechanical or welded branch fitting to pipeline, piping or equipment in service while while it is under pressure or has been depressurized but has not been cleared for conventional construction method. , and creating an opening in that pipeline, piping or equipment by drilling or cutting a portion of the pipeline, piping or equipment within the attached fitting.

Hot tapping is usually performed when it is not feasible, or it is impractical, to take the equipment, Pipeline or Piping out of service, or to purge or clean it by conventional methods.

The decision should only be made when

(1) continuity of service is essential,

(2) shutdown of the system is impractical,

(3) documented procedures are followed,

(4) special equipment is used which will provide effective protection for employees.

A hot tap connection can often be safely made without interfering with the process operation.

Hot-tapping is potentially hazardous and therefore should only by undertaken when shown to be technically feasible and to offer a clear advantage over alternatives.

This advantage may be economic and, in some situations, the safety and environmental risks may be less than those associated with more conventional methods.
