Anti-pollution stopper
Pronal anti-pollution stoppers have been designed to remain permanently fitted in water and sewer pipes so as to quickly stop the pipeline when accidental contamination occurs.
To do this, simply trigger stopper inflation using a remote-operated system.
Once inflated, it will prevent any toxic fluid spill or spreading of firefighting water in the pipeline. |
|
PRONAL inflatable stoppers are used:
- to test pipes for leaks under pressure
- to isolate pipes during maintenance operations
- to make temporary seals to avoid run off of toxic products.
Thanks to the materials employed and the suitability of their design, PRONAL inflatable stoppers are ideal for all types of pipes.
Advantages:
- simplicity and speed of installation,
- completely leakproof,
- safe to use,
- suitable for a wide variety of pipes : concrete, cast iron, steel, stainless steel, PVC,
- sturdy and long service life.
A highly diversified range of products :
- one of the widest range of products on the market,
- from standard to made-to-measure : models for low pressure and high pressure environments (over 100 bar depending on requirements)
- a choice of shapes : cylindrical, ovoid, square...
- no size limits : up to 3,000 mm in diameter,
- specific models which comply with particular specifications. |

Float-in Bags are fitted with a reinforced front cover and tension lugs. The CR material ensures increased resistance to chemicals. Working lines are secured to the tension lugs using carbine hooks and the pipe sealing bag can be floated into the pipeline without any difficulty.
Only four sizes are needed in order to seal pipe dimensions ranging from 70 mm to 1200 mm (2.8 inch to 47 inch). The float-in bag program is rounded off by a chemical variation in addition to the basic design.
In this case, all metal parts on the float-in bag are made of stainless steel and the integrated inflation hose (10 m/32 ft.) guarantees the corresponding safety distance to the area of danger. |

An Expansion joint of rubber is a made flexible union with natural or synthetic elastómetros, weaves of reinforcement designed to compensate extensions and contractions by temperature variations, damping and absorption of vibrations in facilities of transmission of fluids.
The problems of vibration, noises, shock, corrosion and tensions can be solved early incorporating the Expansion joints of rubber in the systems of conduction of fluids. |

Why seal drains permanently with cement? Use our Conical Drain Plug instead.
- Seals drains from 2" to 4" in diameter
- Removable-allows your drain to function normally when plug is not in place
- Non-mechanical-just wedge Plug in drain; ideal alternative to permanently sealing your drains with cement
- Durable polyurethane plug forms a tight, chemical-resistant seal; removes easily with hand tools to restore drain function
- Perfect for general maintenance use-you can keep the Plug in the drain with the drain cover in place |

Excessive levels of noise can damage the sensory "hair" cells that process mechanical energy into the tiny electrical nerve impulses that our brain perceives as sound.
Hearing loss caused by exposure to noise at work continues to be a significant occupational illness. 3M offers a wide range of ear plugs including disposable, reusable and banded ear plugs. There is also the option to choose from corded or uncorded within disposable or reusable ear plugs. |

| E·A·Rsoft is made from a slow expanding, environmentally friendly, polyurethane foam material. We have successfully developed an earplug that provides evenly distributed pressure, giving flexibility, a good seal with optimum comfort. E ·A ·Rsoft Yellow Neons are also available with a blue vinyl connecting cord, for use in food manufacture and food process industries. |

Selecting the right protection for your workers means more than choosing the earplug with the highest NRR. A better way to ensure that hearing protection is used consistently and properly is to select earplugs by Comfort Profile. That means considering all the features that make one earplug work and fit differently than another: material, shape, size and NRR. Howard Leight makes it easy to compare products and ensure that all your workers receive the right fit and protection.

Hands off the foam!
What could be easier? These bright purple earplugs are soft, shaped and ready for immediate use - right out of the packet. No roll down required. Just grab the LiveWire stem for a firm, deep and hygienic insertion. |

UNISORB® Heavy Duty JAKEBOLTS®
Constructed entirely of steel, the Heavy Duty JAKEBOLTS® are tough, durable, and MIG welded watertight to prevent contamination of internal components during installation. Each JAKEBOLT® comes supplied with a centralizing bushing which doubles as a seal and protects against contamination during grouting.
JAKEBOLTS® are manufactured with retractable studs to allow a clear floor condition at any time. Anchor studs can be adjusted to project above the floor from 0 to 6" or 0 to 12", depending on the bolt specified for the installation. The entire internal anchor assembly can be adjusted laterally as well as vertically to compensate for normal construction variances in both hole location and machine foot thickness.
The Heavy Duty JAKEBOLT® incorporates 90,000 psi tensile strength steel in the bolts. The all steel anchor assembly is designed for service under the most severe conditions. |

The Inflatable Pipe Purge Systems have a number of distinct advantages leading to big cost savings:
Use Less Inert Gas
The volume to be purged is localized. For a typical pipe run, the volume of gas used is less than 2% of that required for a conventional purge.
Faster
The system is quick + easy to install. It can be positioned accurately and the dams inflate instantly. Purging time is a fraction of that required to purge by conventional methods.
Easy to Use
'Inflatable Pipe Purge Systems' simplify the process of inert gas purging, Training is Minimal.
Improved Quality of Welds
Leading to bright, shiny, coke and oxide-free welds very quickly. The process involved is highly reliable. It gives regular, controlled high quality results.
Fast Payback
The 'Inflatable Pipe Purge System' pays for itself in just a few welds.
Highest Standards
We manufacture to Nuclear Quality with Nuclear approved materials.
High quality circumferential butt welding of pipe to pipe and pipe to fitting requires inert gas to be used inside the bore to prevent oxidation and notching of the root penetration weld bead.
The best system devised for this is the Inflatable Pipe Purge System.
It is quick, reliable and easy to use, the volume of purging required is kept small, resulting in significant savings in both time and the volume of inert gas used.
|
|
Each Quick Purge is covered with heat protective materials on the inside, so as the higher temperatures closer to the weld do not damage the device.
Central Sleeve - Reduces purge volume typically a 36" pipe diameter will purge below 0.1% oxygen in less than 10 minutes.
Sizes from 8inch to 72inch (200mm - 1800mm)
Feedback off the end users of the quick purge have reported savings of up to 83% ! on the purge time!
Saves on purge gas, as the volume needed to be purged is greatly reduced.
This system pays for itself in a few welds!
