Crystal Industrial’s High Pressure Access Systems from India

Crystal Industrial’s High Pressure Access Systems from India are special pipe arrangements which allow inward access to manufacturing plant vessels and piping working under full process conditions. These gadgets can be placed or recovered securely and without plant close down, at operating pressures up to 3,600 psi.

Crystal Industrial’s High Pressure Access Systems from India comprise of the following parts:

• an Access Fitting Body
• a Plug Assembly

Crystal Industrial’s High Pressure Access Fitting Bodies from India

Crystal Industrial’s High Pressure Access Fitting Bodies are accessible in styles that might be welded (Flareweld, Socketweld, and Buttweld), threaded (NPT), or flanged (API, ANSI RF, ANSI RJ) to the piping or vessel wall.

Flareweld bodies are the most extensively utilized. These bodies include a strengthened welding neck and have a radius machined at the bottom to suit the shape of the pipe or vessel to which the body is joined.

Crystal Industrial’s Access fittings from India are produced from materials which meet NACE MR-0175 descriptions for sour service. Selection of material for the access fitting body depends on least working temperature and process flow corrosion. “Standardized” temperature materials are suited for use above a least working temperature of – 20°F (- 29°C). “Low Temperature” materials must be chosen for least working temperatures less than this value.

Crystal Industrial’s Corrosion Monitoring Systems standard material description for Flareweld, Socketweld, Buttweld, and NPT bodies is AISI 1018 for standard temperature and ASTM A350LF2 for low temperature. For flanged connections, ASTM A105 is utilized for standard temperature and ASTM A350LF2 for less temperature. In any case, all access fitting parts can be made to arrange in any client-specific material; carbon or stainless steel, duplex materials, or other more exotic alloys.

All the Crystal Industrial’s access fitting bodies from India have an outer 3-inch ACME thread, which is utilized to connect the service valve while recovery operations. Access fitting bodies must always be fixed with a cover which is intended to secure both outer thread and even the service valve protective surfaces.

Crystal Industrial’s Hollow Plug Assembly from India

The standard Hollow Plug Assembly comprises of:

• Hollow Plug Body.
• Primary Packing.
• Hollow Plug Packing Retaining Nut.
• Probe Packing.
• Hollow Plug Seal Nut.
• Pipe Plug.

The hollow plug enclosure sustaining nut holds the main packing in place to permit an essential seal between the hollow plug and the access fitting body. The hollow plug seal nut holds the probe enclosure in place to permit an essential seal between the hollow plug and hollow plug seal nut.

The threads on the hollow plug which connect with the access fitting body are right-handed, while its bottom uses left-handed threads. This provision of right and left-handed threads assures that the operational parts of the observing gadget can’t get unscrewed amid the recovery procedure.

The inward bore of the access fitting narrows down so that if the observing gadget or the plug holding nut joined to the plug become loose, it can’t fall through the access fitting body into the line (however will stop at a narrowing just beneath the packing seat). It might then be recovered utilizing a fishing device intended for this purpose.

The below mentioned choices are accessible for the Crystal Industrial’s hollow plug assembly:
1) Metallurgy changes to ferrous and non-ferrous alloys for specific service.
2) Packing material is altered for specific service.
