In the process industries, pigging refers to technology that uses specialist projectiles to recover, rather than waste, residual liquid in pipelines or industrial tubing. It has progressed from basic equipment used to clean oil pipes, to advanced, fully automated industrial product recovery and liquid transfer technology used today.

Pigging technology has been around in different forms since the early part of the twentieth century. Today, a wide variety of sectors, industries and applications that process liquids use pigging to reclaim liquids from pipelines and tubing, reduce waste and improve the efficiency of their manufacturing and production processes.

Pigging has many benefits, but its basic purpose is to remove or recover residual liquid that remains in a pipeline or tubing after liquid has been transferred from one location to another. The main reasons organizations in process industries use it is to recover product, which increases yields and reduces waste. Process industries also use pigging to clean the inside of pipes and tubing, transfer liquids, reduce the use of cleaning fluids, use less water, save time, improve process efficiency and ultimately increase profits. In addition, because pigging saves resources, product and time, it also helps towards sustainability.


HPS designs and supplies high quality launch, receive, return and drop-off stations to meet the precise needs of your system. Each type of station consists of a variety of specialist valves, solenoids, uniquely designed pipework and other components to enable smooth and efficient system operation.

HPS patented process pigs are specially designed for highly effective, reliable and efficient hygienic pipe line pigging, Used by many of the world’s largest liquid processing companies and suitable for a wide range of products. These include food and beverages, chemicals, paints, coatings, lubricating oils, household and homecare products, personal care liquids, pastes and gels, cosmetics and many other applications. Ideal for product recovery, liquid transfer and pipeline cleaning, HPS pigs have a typical recovery efficiency of 99.5%. They’re guaranteed for 30 000 metres or 18 miles of use (unmatched in the industry), and travel around bends while maintaining full body contact.

A pig detector is a device that determines the presence of an HPS pig when in it’s in close proximity. An essential component of pigging systems, pig detectors are usually located close to launch and receive stations, enabling highly efficient, safe and reliable operation – whether automated, semi-automated or manual.

The Solid Seat Ball Valve can withstand the demanding environments of process applications. The robust design has minimum wearing components, and the valves offer low maintenance, ease of operation and reliability. The valve can be completely dismantled and offer a clear passage, which means no pressure loss. It provides optimum efficiency for pigging situations and has been designed for use with HPS pigs, although it can be used in installations without pigging to aide process routing.

Piggable Product Distribution System that replaces traditional flow plates or bend panels. It offers fully flexible product distribution and product recovery (pigging) from any source to any destination. It incorporates the use of full bore hygienic Swivel Joints (Roto-Couplings) to enable each arm to be manoeuvred easily to the desired position.

The Inflatable Seal Ball Valve (ISBV) has been specially designed and developed for use in sanitary and hygienic pigging applications. Sometimes referred to as a Clean In Place or “CIP-able” ball valve, it incorporates unique inflatable seal technology and has many benefits over a regular ball valve.


Whatever control system that customer prefer; Standalone or Integrated Automatic Pigging System, We will supply the design and construction to meet the requirement in every project. To automate the pigging system, even it was simple or complex, will increase process speed, productivity, and efficiency. It also enhances safety and reduces the chances of human error. The closed-loop design also ensure extremely high levels of safety, efficiency and reliability, while maintain the maximum microbiological, hygienic and sanitary levels of cleanliness.
