Add branches and tie-ins while the system stays live and in service.
Hot Tapping
Pressurized branch connections on live systems so production keeps running while new tie-ins are made.
ES&C INC. — Energy Services & ConsultingIndustrial Service & Equipment Solutions
Precision Industrial Field Services
ES&C INC. solves critical in-place industrial work — hot taps, line stops, field machining and sealing-surface repair — backed by extensive field experience on demanding industrial systems. Practical field experience, responsive execution, and one objective: keep your downtime as short as the work allows.

Capabilities
Built around the work that cannot wait for a shutdown
Nine field-proven service lines, delivered by the same people who scope them. Equipment sales and rentals back the crews up when you want to run the work yourself.
Restore sealing surfaces without removing the equipment from the line.
Field Machining
On-site machining of flanges, valve seats, bores and sealing surfaces where removal to a shop is not an option.
Control thermal cycles in the field for weld and joint integrity.
Heat Treating
Pre-heat, post-weld heat treatment and stress relief in the field, with recorded thermal cycles.
Why operators call us
Field experience first, paperwork that follows
We work in place
Machining, tapping and isolation performed on the equipment where it stands, avoiding unnecessary removal and transport. Crane or lifting support is arranged when it is needed to mount, position or handle the machine safely.
Responsive execution
Scope reviewed quickly, tooling mobilized deliberately, and the work window respected. Downtime is the number we care about.
Technical judgment on site
Our consulting and execution come from the same team, so method changes get decided at the joint instead of over email.
Documented results
Torque values, thermal cycles and machining tolerances recorded and handed over with the work package.
Representative project experience
Selected in-place interventions
Case detail is structured as challenge, scope, execution and technical result. Work performed before ES&C was founded is labelled as prior-employer experience.
Hot Tapping / Line Stopping
36 in. Hot Tap & Line Stop
Hot tap and line stop on a live crude-oil transfer line at an offshore Gulf repump station, holding isolation through the repair window without taking the transfer system down.
Representative professional experience — performed by ES&C leadership prior to founding ES&C, while employed by another service provider. Not an ES&C contract.
Hot Tapping
8 in. Hot Tap on a Live Natural-Gas Line
An 8 in. hot tap performed on a live natural-gas line, allowing a new tie-in to be established while the line stayed in service.
Field Machining
8 in. Class 600 Cryogenic PSV — Gasket Surface Repair
A new 8 in. Class 600 cryogenic PSV required gasket-surface correction ahead of scheduled testing the following morning. ES&C mobilized portable field-machining equipment to the site and resurfaced the gasket sealing area as required, supporting the customer's time-critical test schedule.
Field Machining
Pressure Drum Repair
Field repair of a pressure drum: field machining equipment mounted in place to resurface the gasket sealing area and return the vessel to service.
