Mechanical Access System

Mechanical Access Fitting Assemblies are designed for intrusive corrosion monitoring applications that require the insertion and retrieval of probes, coupons, and chemical injection devices against full system pressure. These fittings are engineered to meet stringent Oil and Gas industry standards, ensuring safe and reliable operation in both onshore and offshore environments.

Various type of Mechanical Access System:

Mechanical Access System without Tee

Used for standard corrosion and erosion monitoring installations.

Mechanical Access System with Tee

Designed for chemical injection or sampling applications, featuring a side outlet for fluid injection or process sampling.

Welded Access Fitting

Suitable for applications requiring a direct welded connection to the pipeline or vessel

Various type of mounting options:

Flareweld Access Fitting

Buttweld Access Fitting

Socketweld Access Fitting

Hydraulic Access Fitting Assemblies

(For Intrusive Corrosion Monitoring Systems)

Hydraulic Access Fitting Assemblies are designed for intrusive corrosion and erosion monitoring applications that require the safe insertion and retrieval of probes, coupons, and chemical injection devices while the system remains fully pressurized. These assemblies enhance operator safety, enable quick and efficient handling, and ensure reliable pressure containment, making them suitable for both onshore and offshore installations.

Hydraulic Access System

The Hydraulic Access System allows retrieval operations to be carried out hydraulically under pressure, eliminating the need for mechanical threading operations during insertion or removal. It provides improved control, sealing integrity, and reduced operator effort.

Various type of Hydraulic Access System:

Hydraulic Access System without Tee

For standard corrosion / erosion monitoring and
inspection tasks.

Hydraulic Access System with Tee

Designed for chemical injection or sampling applications, featuring a side injection point for fluid or inhibitor.

Welded Access Fitting

A specially engineered design intended for permanent installation where direct welding to the pipeline or vessel is preferred.

Various types of Welded Access Fitting:

Flareweld Hydraulic Access
Fitting

Buttweld Hydraulic Access
