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.

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. Features of intrusive pig signals Can be used with a variety of pigs - Foam pigs, Metal bodied pigs, Polyurethane pigs, Spheres, Mandrel pigs Provided with mechanical and visual indicator, electrical indicator or a combination of both for maximum flexibility Can be fitted to all pipeline sizes over 1" Can be fitted on majority existing signaller bosses for best flexibility Does not use dynamic seals Low maintenance costs and emission controls Fitted on hot tapping systems Bi directional and omni directional trigger mechanisms

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. VKVC will design pig launcher and receiver systems which are 'tailor-made' to meet specific operational requirements.VKVC manufactures extension Pig Barrels to extend major barrel length of Existing Pig Barrels. Extension Pig Barrels consist of one quick opening closure and one adaptor to hook up the extension Barrel to existing Pig Barrel QOEC.

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.

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

Quick opening closures are pressure retaining structures designed to provide access to pipelines and pressure vessels.Our Quick Closures provide safe and quick access to pipeline and pressure vessels. They are built to meet all required international design codes and can be used in horizontal, vertical, inclined or declined applications. We offer Clamp, Bayonet and Ring lock Closures as required by Clients. Approved Design ASME VIII Div.1.states that "Quick-actuating or quick opening closures are those that permit substantially faster access to the contents space of a pressure vessel than would be expected with a standard bolted flange connection. The requirements of other pressure vessel codes, such as ASME VIII Div. 2 and PD5500 can be complied with as well as ASME U code stamps. This code stamping confirms that the quick opening closure has gone through rigorous shop inspection by an ASME Authorized Inspector. We offer EN 10204 3.1 & EN 10204 3.2 certification as required. Typical applications for the quick opening closure include, Filter vessels, Strainers, Separators. Pig launchers and pig receivers Metering skid systems We offer Inconnel / stainless steel cladding on our Closures.

  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.    

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.

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.

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. BENEFITS & ADVANTAGES 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.
