Pipeline Closures from Drinkwater Products

Pipeline closures are of crucial importance in pipeline pigging. A pipeline closure must be opened up to provide access to pig trap during launch and recovery operations. Opening the pipeline closure during insertion or removal of a pig, presents a risk of gas and air mixing and resulting in an explosion. As suppliers of pipe pigs, Drinkwater Products aim to provide clients with pipeline closures that are designed to save time and improve operational safety during opening and closure of a vessel.

Pipeline closures require regular cleaning and maintenance, including greasing the hinges, sealing surfaces and O-rings in order to ensure smooth and effective operation over years of service.

Soluble pigs are solid sphere shaped balls or cylinder shaped plugs. Oil soluble pigs contain micro-crystalline wax, paraffin inhibitor and pour point depressant. Water soluble pigs contain a water-soluble surfactant and corrosion inhibitor.

Soluble pigs are used to clean out paraffin deposits and other unwanted accumulations inside of pipes.

Soluble pigs (oil-soluble type) contain paraffin inhibitor and pour point depressant. The residual traces of inhibitor help prevent re-deposition of paraffin for a short period of time. The pour point depressant helps the oil that contacts the pig flow easier at lower temperatures.

Soluble pigs can be used in any length lines and are very inexpensive as compared to other pipeline pigs. Pigs do not interfere with other production and pipeline chemicals.

The dissolving rate of pigs is a function of fluid temperature, relative fluid movement, friction, and absorb ability of the crude. These conditions vary greatly with each system. The melting point for our standard pig is about 145F. Special-order melt point pigs range from 125F to 180F. All pigs will dissolve in fluids with temperatures below their melting point (just at a slower rate). Some fluid movement past the pig is necessary to dissolve the pigs if the fluid temperature is below the pig’s melting point.

The number of pigs to be used is based on the amount of accumulation, length of pipe, temperature of fluid and other factors. Regular periodic pigging is recommended to keep lines clean and prevent paraffin from becoming too hard or thick to remove.

Drinkwater Products offers any of the chemical sticks below to meet your specific requirements.

Soap sticks in general are designed to foam the water in the tubing, therefore lightening the fluid column and allowing the formation of pressure to unload the fluid from the well.

Oil foam sticks are designed on the same principle as the soap stick, but used in wells that have a fluid column composed of 75% condensate or greater. 

Acid sticks are water-soluble sticks that release acid down-hole in water injection wells to remove carbonate scale and rust deposits. Acid sticks are a combination of acid, surfactant, dispersing agent, iron sequester, and inhibitor in solid form.

Acid caps are 100% active water-soluble tube sticks that release acid down-hole in producing and water injection wells to remove carbonate scale and rust deposits.

S&B pellets are water-soluble pellets designed to release acid down-hole in water injection and producing wells to remove carbonate scale and rust deposits. S&B pellets are a combination of acids, surfactant, dispersing agent, iron sequester and inhibitor in a solid pellet form.

Drill bit sticks are condensate-dispersible water-soluble sticks containing a combination of surfactants and friction reducer. Drill bit sticks will perform in the presence of salt and fresh water systems.

SAPP Sticks (sodium acid pyrophosphate) are condensate-dispersible, water soluble sticks containing a combination of surfactants, blended with a sodium acid pyrophosphate. SAPP Sticks will perform in the presence of salt, or in fresh water systems.

Gas sticks are water-soluble solid sticks designed to generate gas and provide agitation energy to the foaming agent in a totally dead watered-up gas wells. The gas stick is a water soluble tube containing a surfactant foamer and a gas producing agent.

Fizz foam sticks are water-soluble sticks containing a combination of surfactants and additional additives to self activate and speed up the foam stick dissolving rate and activation of the foam process down hole in the existing produced fluids. The self activating additive and surfactants react immediately upon contact with water and creates an effervescing effect to help establish the foam column required to help remove the fluids from down hole in most cases. The fizz foam stick has been found to be effective in speeding up the foaming process in wells with bottom hole temperature below 90 degrees Fahrenheit. In addition to the effervescing effect of the fizz foam stick, natural gas bubbling through the water-column and surfactants produces foam, which can help remove water from watered-up gas wells.

The well rescue pack was specifically designed as a last resort for your watered up gas well. Dead gas wells lack the agitation required to benefit from conventional soap sticks or liquid foamer. Generally, once a well is dead, unless you are able to shut it in for long periods and build up enough bottomhole pressure to unload the fluid, your options are limited to expensive mechanical methods (swab units, gas lifts, pumps, etc.)

Corrosion inhibitor sticks are available in both oil soluble and water soluble. They are primarily used to control common corrosion problems found in producing oil and gas well systems. 

Paraffin inhibitor sticks are oil-soluble sticks that release paraffin inhibitor to help reduce paraffin deposition from crude oil in production systems. Paraffin inhibitor sticks contain a combination of micro-crystalline wax and a special crystal modifier. These ingredients contribute to an effective inhibiting process on certain ranges of molecular weight paraffins.

Salt sticks help keep the salt in solution by salt cheleating action and helps prevent this build up from occurring or greatly reduce the situation.

Scale inhibitor sticks will prevent carbonate types of scale from depositing in casing, tubing and flow lines.

SI-403 is a blend of surfactants that produces high, stable foams in all brine and a wide range of pH’s. In addition to brine contamination SI-403 will tolerate up to 10% oil, a moderate amount of amine-based corrosion inhibitors, and 50% clay solids and still perform as an effective foaming agent. SI-403 is highly biodegradable.

Well cleaner sticks help with pressure build up, loss of vacuum, decrease injection rates and more.

SIP-100 exhibits what is known as the “threshold effect”. This happens when very small amounts of a scale inhibitor (SIP-100) can help keep large quantities of scalants in solution. The phosphonates in SIP-100 are very effective threshold scale inhibitors. Data shows that one molecule of phosphonate can inhibit 5,000 to 10,000 molecules of scalant. This appears to be done under present theory by the absorption of the threshold agent (SIP-100) on the “growth sites” of the scalant crystal; thereby the growth pattern is altered so that crystals are formed more slowly and are not as likely to clump together to form scaling problems on equipment. They can be considered as distorted.

CIP-25 pellets are water-soluble pellets designed to release corrosion inhibitor and control corrosion from various sources. CIP-25 pellets exhibit surface activity which aids in solids removal and control while helping the breeding grounds for micro-organisms. CIP-25 pellets contain ammonium quaternary salt in pellet form.

Antifreeze inhibitor sticks are special water-soluble sticks containing a combination of stabilizers and glycol-based antifreeze. Natural gas bubbling through the fresh water-column, glycol-based antifreeze and stabilizers produces an aqueous product, which can help reduce the freeze point of the produced water in the production string, flow lines and surface equipment.

H2S scavenger sticks are an organic sulfide scavenger designed to help down-hole with hydrogen sulfide that is entering the well from the bottom perforated area and creating problems for the well system.

CORSCAV sticks consist of a blend of a catalyzed sodium sulfite type oxygen scavenger and ammonium quaternary salt for corrosion inhibition, contained in a fast dissolving water soluble paper tube and dissolvable salt plug.

Oxygen scavenger sticks are a catalyzed sodium sulfite type oxygen scavenger that is compatible with high hardness brines. Oxygen scavenger sticks help control corrosion caused by the presence of oxygen by absorbing and scavenging the oxygen out of the fluid sources contaminated.

HA-FWF sticks are special foam sticks that contain 100% active surfactants, friction reducer and foam stabilizer in water-soluble tubes. Natural gas bubbling through the water column and 100% active ingredients produces foam which can help remove water from watered-up gas wells.


Drinkwater Products can provide a variety of probe rods and accessories to help you find those pipelines underground.

Foreman Night Caps are made of lightweight metal, so they generally can be installed by one person without assistance. A few turns of a single bolt forces disc plates together pressing a rubber gasket against pipe walls as a barrier to unwanted items. Night Caps, however, are not pressure-holding devices.

Field tested by major companies and practical pipeliners, Foreman Night Caps have been proven both durable and long-lasting. The rubber used on the Night Caps can withstand a temperature range from -40° to 260 °F. These Night Caps can also be vented when desirable.

Foreman Night Caps outperform inefficient caps, sacks, sheet iron plates and canvas covers, and are reusable indefinitely. Replacement parts such as gaskets and other components are available.

Foreman Night Caps are available in 1 1/2 to 48 inch sizes and guard against water, mud, rocks, skids, bottles, cans and other accumulation found in pipelines.

Portable holiday detectors are designed for various pipeline, plant, and other surface applications where the inspection surface remains stationary and the detector is moved over the inspection surface. High voltage detectors are used for thicker surface coatings, such as those used on pipelines and other industrial applications. low voltage, wet sponge detectors are used for thin film applications.

Various jeep meters are used to verify voltage of portable detectors.

Electrodes are used to transfer voltage from the holiday detector to a surface. Various designs are available to meet type and size requirements.

In-plant detectors are similar in design to the portable detectors. The key difference being, the inspection surface moves past the stationary detectors.
