CASING END SEALS:
Pipes are situated inside a casing near rivers, highways, railways or other such locations where safety is required.
The opening between the carrier and the casing needs to be protected to prevent foreign material to enter.
This opening is an attractive spot for corrosion and so is required to be kept dry.
Custom designs can be made depending on whether it is a new installation or for retrofitting. Nik-San casing end seal are economic, easy to install and a clean solution.
Nik-San's Pipe Rollers supports pipeline Teflon coated contact heavy duty pipe rollers â??Vâ?? type roller points prevent pipe contamination. Dual-roller style, moulded, oversized roller bearings, optional horizontal roller for small-diameter pipe, Forklift pockets and lift hooks for easy movement on jobsite. Lightweight rugged construction to withstand rough handling. Color coated to resist spatter. Helps protect exterior of pipe during crossing installations and reduces drag/pulling forces substantially.
SPIRAL WOUND GASKET
The spiral wound gasket is suitable for use across a wide pressure range and is therefore virtually applicable.
The spiral wound gasket can be used to seal fluid pressures up to 250 bar and cryogenic temperatures as low 200C and up to elevated temperatures 550C.
Due to its sturdy design the spiral wound gasket is simple to install without causing damage (although extra care should be taken during transportation and installation of large diameter gasket without guide rings).
The outer guide ring serves to locate the spiral element centrally on the flange faces and prevent blow-out.
By combining different winding materials and metals the gasket can be tailored to a wide variety of operating conditions.
Due to its non-adhesive character the gasket is easy to remove after service.
The gasket does not cause damage to the flange faces.
BENEFITS OF THE CENTRING RING
The spiral wound gasket outer centering ring provides the following benefits:
Optimum location between the bolts.
Protection of the spiral wound element.
Additional security against gasket blow-out.
Acts as compression limiter preventing overloading and over compression of the spiral wound element.
Prevents radial-flow of soft fillers, such as P.T.F.E. For these reasons it is preferable to use spiral wound gasket with outer centering rings. On the outer ring is marked with nominal size, pressure class, standard and materials.
BENEFITS OF THE INNER RING
The spiral gasket inner ring provides the following benefits:
Prevents radial-flow of soft fillers, such as P.T.F.E.
Reduces turbulence-minimizing flow resistance and crevice corrosion.
Acts as a heat shield when the spiral wound gasket is subjected to high temperatures. Inner and outer rings are particularly recommended for use on spiral wound gaskets exceeding class 600lbs, but specifically recommended for high temperatures and pressures to optimize the operational reliability of the spiral wound sealing element.
MATERIAL SELECTION
Material selected for the inner ring and winding metal is usually the same as the flange metal, in order to prevent corrosion and differential expansion problems. The outer centering ring is generally manufactured from carbon steel with an anti- corrosion treatment; however, the ring may also be manufactured in the same metal as the flange to prevent corrosion problems.

PIPELINE PIGS
Pigs are devices used to primarily clean Pipelines over the years they have been developed to do different functions. Nik-San is an experienced and renowned manufacturer of Pipeline Pigs. The strong reputation has been established over many years of manufacturing and supplying pipeline pigs to operators and contractors in the oil, gas and process industries. Quality, Reliability and Innovation are the main Pillars of our Company. Nik-San works closely with operators to design and produce Pigs which offer the best solutions to the pipelines where they will be used. To achieve this, Nik-San utilizes its design chemistry and engineering expertise to develop Pigs tools that are tailored to meet the specific requirements of each pipeline. Nik-San manufactures a full range of utility pigs including:
Bi-Directional Pigs, Cleaning Pigs, Four Cup Pigs, Batching Pigs, Magnetic Pigs, Gauging Pigs, Two Cup Pigs, High Density Foam Pigs, Medium Density Foam Pigs, Low Density Foam Pigs, HD PU Coated Foam Pigs.
CASING INSULATORS:
Casings are used to protect pipelines. These pipelines usually run along highways, railway lines or regions with high activity. The pipeline is needed to be separated from the pipeline. Nik-San casing insulators are tubular pipe supports; that electrically insulate the pipe and prevent damage. Electrical insulation is required to prevent shorting between the carrier pipe and the casing.
ADVANTAGES
Easy to install
Efficient to use
Requires no special tools or grease
Corrosion protection
Insulating
Leakage prevention
Not required to fill sand in the casing (labour intensive)
