For pipelines having short launcher / receiver barrels, VKVC designs, manufactures, tests, installs and commissions extension barrels for existing pig barrels. These barrels extend the length of the launcher / receiver. Adaptors are custom made to suit any make of quick opening end closure (QOEC) / quick opening closure (QOC) available over extension barrels. VKVC extension barrels enables intelligent pigging to be carried out on the existing barrels. A major advantage is that no hot work is required for installation of the extension barrels. VKVC pig extension barrels are custom designed by the engineering team at VKVC. The entire unit is precision machined in house at the VKVC machine shop and fabrication facility. Please contact us for more information.

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. VKVC 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.

• 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)

A VKVC pipeline coupling is one of the safest ways to couple pipelines in the oil, energy and gas sector. They allow the pipeline to resume operation immediately so that costly downtime is avoided. VKVC couplings provide a safe and reliable method to join low, medium and high pressure pipelines. Please contact us to find out more.

In addition to pigs and launchers and receivers, VKVC also provides pig handling systems and jib cranes. Being equipped with pig handling systems is a must for pig stations and facilities. Loading and unloading the pigs are key points where accidents resulting in danger to manpower and equipment damage can occur. The pig handling system can be manual or hydraulic. A crane alone is not sufficient to handle pigs as it is difficult to maneuver the pig in and out of the pipeline. Also a jib crane alone cannot ensure if the front cup is correctly positioned in the reducer at the pig launcher. VKVC pig handling systems are designed and engineered to ensure safe operation.

Multiple pig launchers are designed to allow the sequential launching of pigs and spheres. Using our automatic multiple pig launching system a series of pigs can be launched into a pipeline without having to repeatedly depressurise and re-pressurise after each pig launch. The process can also be controlled from a remote location. This is particularly relevant on unmanned platforms such as offshore platforms and sour service applications. Sphere release fingers on sphere launchers are used to control the release of a series of spheres into a pipeline.

In addition to the supply of newly manufactured pig launchers and pig receivers, VKVC provides an inspection, maintenance and refurbishment service to existing in service pig launchers and receivers.Quick Opening and closures .

VKVC flow tees are used in pipeline systems at branched connections and pig launcher and receiver systems. The tees can be barred or sphere. Barred tees help the pig to negotiate the branch. Tees are available customized as per customer request.

A Pin-Hole Leak Repair Clamp is a pipeline repair technology that is used when the leakage in the pipeline is of very small or minute size. Installation of these clamps is very simple. VKVC offers installation services for the clamps as well. Pressure and class range of VKVC Pin-Hole Clamps are given in the following table. VKVC provides custom sizes and configurations depending on client need basis.

Unavailability or lack of proper dedicated pig/scraper launcher and receiver facilities may cause a pipeline that is traditionally accepted as piggable to be considered non-piggable. Conventional pigging methods and technology are not suitable for such systems.Unavailability or lack of proper dedicated pig/scraper launcher and receiver facilities may cause a pipeline that is traditionally accepted as piggable to be considered non-piggable. Conventional pigging methods and technology are not suitable for such systems.
HOW TO PIG NON PIGGABLE LINES? The best or ideal pipeline for pigging is when the following conditions are met

• A straight pipeline
• A uniformly round internal diameter without any change in wall thickness and weld penetration
• Internal surface is polished
• No valves or offtakes

In reality all of these conditions are rarely met and in certain cases none are met.
In certain cases if proper considerations are not taken into account then the line can be completely unpiggable.

Pig Signals are devices which detect the passage of a pig and then inform the operators about this passage at crucial points of the pipeline. Pig signals are located at the pig launching, pig receiving and other critical points along the pipeline. Majority pipeline owners chose VKVC pig signals for their pigging needs due to the ease of operation and installation along with an uncomplicated design. Moreover the experienced pig locator professionals from VKVC make the pigging operation fast and efficient.

Insulating Joints are used on pipelines to provide electrical isolation to prevent corrosion. They provide current spreading on cathodic protection systems. They provide electrical separation between pipeline section and the adjoining neighboring structures and pipelines. Wherever practical, the VKVC insulating joint is intended to be installed above the ground, or in an inspection pit in dry conditions to limit the possibility of electrical bridging across the joint. It is intended to be girth welded between two pipeline sections.

• No loss of integrity due to thermal expansion or ground stress as is common with flange isolation gasket kits.
• In-factory tested hydrostatically and electrically, to 1.5 times their working pressure. Non destructive testing is also available.
• Maintenance-free, reliable cathodic isolation of equipment in required isolation applications such as compressor stations.
• No labor intensive, complicated installation procedure required as is the case with isolation gasket kits,
• No inspection pits, vaults or maintenance needed - weld into place and direct bury - reliable, worry-free cathodic isolation.
• Non-conductive epoxy coatings help prevent shorts, both internally and externally.
• Isolation stray currents impressed on the pipe from exterior forces such as electrical transmission systems, earth currents and currents flowing from point to point.
• Excellent bending and torsional resistance.
• Earthquake resistant - acts as a thrust block or joint.

Composite wraps or bandages are similar to tapes; they are wrapped over the defective pipes in layers in conjunction with a putty after surface preparation of the pipe. VKVC composite leak repair bandages are used for repair of metal, plastic, PVC, copper, rubber, concrete, composite pipes etc. The composite generally used is fiberglass reinforced material with a water-activated polyurethane resin coating. Composite wraps or bandages are used extensively in oil & gas, water pipelines etc. Typical advantages include:

• Quick & simple to use, no mixing required
• 30 minutes for successful repair
• Flexible adhering to complicated shapes
• Cost efficient
• Hand-mixable putty; moldable in any shape to fill and seal leaks or cracks of any shape
• Environment friendly material
• Suitable on wet and dry pipes
• Underwater application
• Upto 15MPa of pressure resistance
• Available in various sizes from 5cm to 15cm width

O-rings are available is Viton, Buna N. These O-rings are usable for line stop applications with products: oil, crude oil, diesel, gasoline, GPL, natural gas, hydrocarbons and chemical industrial products.

Cups, brushes, discs and scrapers are spare parts that can be used with older pigs saving cost on purchasing fresh new pigs. These spare parts scrape the pipeline interior while running through the pipe, this loosens up already deposited debris and prevents buildup of new deposits.

Sandwich Valves use a variety of design features used to assist the linestop operations.
