Flanged
The ANSI flange fittings are manufactured in accordance with the ANSI B16.5 - specifications for Flanges and Flanged Fittings
Recent Access Fittings Projects
Some Access Fittings projects we have done for clients
Buttweld
Buttweld access fittings have been designed to be buttwelded directly on to a 2" pipe end
Flareweld
Flareweld bodies are the most commonly used. These bodies incorporate a reinforced welding neck and have a radius machined into the base to accommodate the curvature of the pipe or vessel to which the body is welded
Plug
The plug is a critical component to the Crystal high pressure access fitting assembly, since the plug body provides the seal in the access fitting, thus maintaining line pressure. The plug also serves the important function to hold the monitoring equipment which is exposed to the system.
Custom-built Access Fittings from India
Crystal's Access Fittings from India are specialized piping arrangements that allow internal access to production plant vessels and/or pipework operating under full process conditions. For such access systems, the corrosion monitoring industry standard is based on a 2-inch nominal bore design.
During operation along with a Retrieval Tool and Service Valve, high pressure access fittings from India allow the installation and retrieval of:
-Probes
-Coupon holders
-Sampling probes and chemical injection, nozzles and quills
These devices allow the installation and safe retrieval without plant shutdown, at working pressures of up to 3,600 psi.
Most frequently, high pressure access fittings are used in oil and gas production. In these kind of high pressure operations, users are reluctant to shut down and depressurize process systems to allow removal or installation of corrosion monitoring devices.
High pressure access fittings consist of five basic components:
- Cover
- Access Fitting Body
- Plug Assembly
- Service Valve
- Retrieval Tool
Access fitting body
This is permanently attached with the process plant vessel or pipework. It is a specialized pipe fitting. Access fitting bodies can also be flange mounted or welded.Plug Access
For the installed device, the Plug assembly is the carrier. Based on the type of device being used, a solid plug assembly or a hollow plug assembly is chosen. The plug assembly screws into the access fitting body and seals the fitting's bore to restrict line pressure.Cover
Together with its plug assembly, the access fitting body and cover (designed to protect the external thread) is called access fitting assembly.Retrieval Tool & Service Valve
The retrieval tool and service valve are components needed to perform online installation and retrieval of the plug assembly. When the plug assembly is removed during the retrieval procedure, the service valve is used to restrict line pressure. Just one service valve and one retrieval tool can be used to maintain multiple access fitting assemblies.A variety of devices have been designed for use with high pressure access fittings. Typically the following equipment can be installed into process lines using standard access fitting assemblies:
-Corrosion Coupons
-Linear Polarization Probes
-Thermowells
-Biological Probes
-Electrical Resistance Probes
-Hydrogen Probes
-Erosion Probes
-Sacrificial and Impressed Current Anodes
The following functions can be additionally undertaken with the use of access fitting bodies which incorporate a side-tee.
-Process Sampling
-Chemical Injection
-Sand Monitoring
Crystal Industrial offers two different styles of high pressure access fittings :
Generic design: This system is compatible and interchangeable with access fitting equipment produced by leading manufacturers.
Proprietary design: Incorporates various unique features which are an improvement on the generic design.
