Hot tapping a specialised service offered by us enables the pipeline owner to take a new branch connection from the existing pipeline, vessel or a tank, which is in service and under pressure.  We use a specially designed Hot tapping machines, a full bore valve and either a nozzle pad fitting or a full encirclement fitting (Split tee). Tapping machine uses a specially designed cylindrical cutter, attached to a telescopic boring bar, driven by a hydraulic motor cuopled to a precisely designed gear box. 

Our Specialised equipments are capable of executing

• Hot Tapping on Steel Pipelines for branch connections & Line Stops
• Lateral Hot Tap (Angle Hot Tap) on Steel Pipelines for brach connections
• Hot Tapping on Shells & Vessels (Tank Hot) to create new out lets on a tank/Vessel in service
• Drilling on Steel Pipelines & Vessels for Insertion of measurement probes

We can tap from ½” to 48, at any pressure ranging from vacuum to 110 Bar, at any temperature unto 350 Degree.

Line Stopple/Line Plugging is a specialised service designed for Repair, Modification, and replacement of a Pipeline without shutting down the flow. This Procedure requires In-Service Welding & Hot Tapping as primary operations, which is followed by insertion of plugging head with a sealing element into either ends of the pipeline intended for repair/replacement. This procedure usually requires a bypass connection to ensure that the fluid continues to flow in pipeline through the temporary bypass until the repair/modification work on mainline is complete.

With our specialised, precisely designed equipment set up, we can perform a Line Stopple Operation on pipelines ranging from 6” to 48”, at any pressure ranging from vacuum to 110 Bar, at any temperature unto 350 Degree. 

Our Rage of Line Stop Services covers:

• Line Stop Using Pivoted Plugging Heads (For High Pressure, Ambient & High Temperatures)

• Line Stop Using Foldable Plugging Head (For Low Pressure & Ambient Temperatures)

• Line Stop Using Nitrogen Gas  Baloons ( For Ultra Low Pressure & Ambient Temperaures)

In Service Welding is one of the most critial service to be ever executed on a Live Pipe Line. This enables fitment of Split Tee/Stopple Tees on a Pipiline intended for Hot Tapping or Line Stopple, which is in service and is under pressure. With a Team of Engineers, Quality Inspectors & Welders having an exoperience of more than 15 years in this field, we develop customised Welding Solutions considering the metallurgy of mainline and the fitments, in accordance with API 1104 - Appendix B, ASME Section IX.

Our Cusomised Welding Solutions Include: 

• Welding Procedure Specification (WPS), Prodedure Qualification Test (PQR) & Welder Qualification Test (WQT)

• Thermal Analysis

• Finite Element Analysys

• Positive Material Identification (PMI)

• Non Destructive Tests

• Destructive Tests

• Pre Weld Heat Treatment

• Post Weld Heat Treatment

When it is not possible to repair/replace the pipelines throgh Line Stop method, We offer the Pipe Repair Sleeves. These are placed on the pipelines in two halves and welded to become a permanent part of the pipe covering the damaged section of it. This operation also requires high precission and special care as we are operating on the weakest section of the pipeline. 

We adopt the same procedure used for In Service Welding, with extra preacutions and safety measure. Our Team of experts conduct a detailed survey on the pipeline to check its feasibility for this operation, which includes Thickness test, Positive Material Identification, Finite Element Analysis, Ultrasonic Lamination (Rolling Defect) Test etc.

Pipe repair sleeves can be used to regain the integrity of pipelines lost due internal corrossion, External Damages such as dents, drags and sufrace deffects such as cracks.

We manufacture and weld repair sleeves starting from 6” to 48” of different thickness and material to suit the mainline.

Cold Cutting is one more specialised service that we offer to cut the pipelines, which are taken off service. We use a specially designed Split Frame Cutting machine mounted on outer wall of the pipeline, with a Specially designed High Speed Steel Carbide tipped tool that rotates around the pipeline. Automatically driven feed screw advances the tool for a minute depth over every rotation, Thus avoiding frictional spark during the cutting operation.

Cold Cutting Operation is an essential part of Pipeline replacement works though Hot Tapping & Line Stopple method. After performing the Line Stop Operation, Eventhogh the Pipeline to be replaced/modified is free from hydrocarbons, Due to the presence of trcaes of Hydrocabons on the inner wall of the pipeline and due to presence of fumes, The Pipeline is not feasible for Cutting & Grinding operations using conventional methods.

Our Specialised equiipments & team of experienced operators ensure Spark free cutting & Beveling which eliminates the fire hazards.

Our Equipment Range is capable of carrying out cold cutting operation on various sizes of pipes starting from 6” to 48”

Horizontal Directional Drilling (HDD) is a Trench Less  method of installing underground pipeline Utilities using a surface-launched drilling rig. Directional Boring/HDD offers significant environmental advantages over traditional method of cut and cover pipeline installations.

This technique is generally used when conventional trenching or excavation is not practical or when minimal surface disturbance is required, Such as Laying a Pipeline across a river, Railway Track, Road Crossing, Freight Corridors, Runways etc.

We are fully equipped with drilling rigs that can enable trenchless laying of Pipelines from 2 Inch Upto 36 Inch.
