24″ Diameter Tivar 88 Pipe Lining

The pictures below are of an application completed at our Langley, BC facility. This involved lining a steel pipe with an internal diameter of 24″ inches and is a job we’ve done several times before. It’s innovative work and we wanted to share some details and pictures in case the application might be of interest to other companies. The customer ships their pipe segments to our facility where the lining is done on site. We have fabricated 3/4″ thick Tivar 88 sheet that comes pre-scored to permit bending. This is important since Tivar 88 is not available in pipe format, so the solution must be made from sheet stock.

As you can see in the second picture there are not too many fixation points. There is a middle strip of plastic serves as a wedge, and the pressure alone holds the lining solution in place (though the strips on either side of the wedge also have fixation hardware, to help secure the wedge). Tivar 88 is a premium grade of UHMW polyethylene and its blue color is readily identifiable. It provides additional strength and slickness that virgin or reprocessed grades of UHMW do not. Tivar 88’s primary benefit is increased material flow and less material hangups. Secondarily, Tivar 88 provides a wear surface that protects the steel from wearing out.

Tivar 88’s lifespan will vary in applications but it is sacrificial, meaning that it will need to be replaced at some point. The performance benefits and increased life of the pipe do make up for the cost of the lining. While not important in this application, Tivar 88 does include UV stabilizer in its chemistry and is suitable for long-term outdoor use. The product also has a long history of success in hopper lining applications

BRAXX Anti-Slip Surfacing

After decades research and design, several “anti-slip” plastic options are now available and BRAXX should not get lost in the shuffle. BRAXX is a standardized UHMW based anti-slip plastic which comes in 36″ x 108″ sheets that are 0.30″ thick. The material comes in two forms “BRAXX Sand” which has a base color of blue dotted, with a sand-impregnated surface and “BRAXX Luns” which has a high-visibility safety yellow colored base and is dotted with LUNS clean coal slag anti-slip grit. BRAXX serves as a heavy-duty replacement for anti-slip tapes and paints. Both types of BRAXX are comparable in price and effectiveness, it comes down to personal preference for color and grit.

Applications for the two materials have few limitations. At 0.30″ thick, BRAXX is non-load bearing and is meant to be placed on top of another surface, typically flooring, stairs, etc. As the plastic is UHMW nothing sticks to it and mechanical fixation is required: you will not to bolt or screw into the substrate. Advantages of BRAXX are that it will not rot, rust, absorb moisture, or otherwise corrode. It is impact resistant and easy-to-install on top of other substrates such as wood, aluminum, or steel. Originally developed for the U.S. military, BRAXX is now available to the general public.

Application Spotlight: Redco HDPE “Play” As Outdoor Tabletops

Recently Terrapin Brewing Co (www.terrapinbeer.com) approached us with an interesting application. They wanted to create a plastic table surface for use at their brewery but this offered some unique challenges. For one, the tables were outside which meant that a UV-stable plastic was in order. Secondly, a variety of properties were important: wear, impact, anti-slip and non-fading color would be desirable. But most importantly the color had to be green and a green that was fairly close to the branding of Terrapin Brewing Co. This is difficult in the world of industrial plastics where custom colors can mean extra costs, long lead times, and minimum order sizes. In addition, an industrial plastic such as UHMW would be overkill for this application and would even have some undesirable characteristics, such as being very slick.

But our representative working on the application made an intuitive leap. We had access to a specialized HDPE material Redco “Play” board designed for playgrounds. In our world of sawmills, mines, and heavy construction this isn’t something we focus on! Nevertheless, Redco Play satisfied all the requirements of the application: it was green, UV-stable, impact-resistant, wear-resistant and had an “orange peel” textured surface so glasses wouldn’t slide around. They were supplied pre-cut into 24″ x 24″ x 1/2″ (thick) squares with a minimum order of 16. Terrapin quickly installed these and you can see a picture they sent us below. They have said they are very satisfied with the material and this application.

Specifying Outrigger Pads

When customers consider a switch to plastic outrigger pads they sometimes don’t know where to start in how to get their quotation. Often we’ll be told that the customer has a certain piece of equipment and to spec a pad size and thickness for them but this over-complicates things a little. Regarding the size of the pad the simplest way is to just get the plastic pads with the same dimensions as the stock pads that came with your rig. If you don’t have your stock pads we can help you out but we do need to know the area of your outrigger feet (length x width and are the feet square or round?).

Thickness is a little trickier to specify. UHMW plastic, commonly used for outrigger pads, is virtually unbreakable but having a pad that is too small and thin may lead it to bend around the outrigger foot as it is more flexible than wood and this may destabilize the rig. A general rule of thumb for most vehicles in the 20-50 ton range is to go with 1.5″ thick pads. 2″ thick is usually good for 50-70 ton but using 2″ pads for lighter equipment will result in less flex with the pad and a more stable lift. Above 70 ton 3″ thick pads are strongly recommended. To reiterate: the plastic will most likely not break on a thinner pad; however, the amount of flex may be undesirable. This is partially dependent on where the pads are being used – we have certain customers who only ever lift on concrete surfaces and thus can use a thinner pad because it has more support. Customers who lift on soggy soils may need thicker pads. As always, we refer to OSHA in that lifts should only ever be done on stable, level, ground.

Plastic Plow Blades & Cutting Edges – Saving The Paving!

One of our employees recently took a couple photos after parking at an area we won’t disclose in Metro Vancouver a day after a recent snowfall. Upon pulling into his parking spot he noticed that every single stall had a large pothole where the snow had been pushed. Having been a weekly visitor to this lot he knew the holes were not there a few days before and therefore must have been caused by the snow removal contractor. The damage is extensive and will be a huge headache to fix! How much money will it cost to repair? What will happen to the reputation of this snow removal vendor?

And it was a completely avoidable disaster that never needed to happen.

Industrial plastic plow blades (or “cutting edges”) have been used for years to prevent this sort of issue. The cutting edges, made of polyurethane, rubber, or UHMW, are simple rectangular strips that are bolted to the bottom of a metal plow or bucket. Therefore it is this softer, non-damaging, plastic surface that actually touches the ground as the equipment scrapes and pushes the snow instead of the metal blade. There are multiple ways the metal-on-pavement contact can cause damage as besides creating potholes the blade can also destroy things like lights or reflectors embedded in the asphalt. Such as is common at airports for example.

The blades are an investment: even the least expensive blade will be at least a few hundred dollars. But how much is that few hundred dollar investment compared to losing contracts, a hit to your reputation as a contractor, and even potential lawsuits? The simple fact is you are “playing with fire” if you don’t have a high-quality plastic cutting blade – it’s an investment that must be made! Several plastics with different prices, properties, and suitability to applications are available so please contact us with the details of your application.

And save the paving!

UHMW Extrusions vs. Machined Lengths

Requesting a quote on a UHMW extrusion is a common request but the option of getting the part machined should not be discounted. Each type of manufacturing process has its pros and cons and a custom extrusion is not always the best method for parts where it is requested. An extrusion is best when you 1.) Have time to permit tooling and initial run manufacturing (8+ weeks) and 2.) Have a very high, ongoing volume of extrusion needed (24,000+ feet per year). If you do not require such a high amount of extrusion than machining can be an option in certain cases, particularly with larger, simple extrusions like rail caps or channel. In regards to channel, we’ve had success adapting our sawmill chain channel extrusions (commonly stocked by our branches) for different applications. A list of our channels can be found by clicking here.

Machined UHMW profiles will likely be more expensive per-piece than extruded profiles. However, the lead time will be less and you will save on tooling costs. The tooling costs of a custom extrusion – often in excess of $5,000 – can make small runs impractical. In those cases, even at a higher per-piece cost, a machined profile will save the customer money. For more information or to discuss a UHMW extrusion or machined profile contact us today.

Anti-Slip Multipurpose Plastic

Slipping is a major hazard. According to the National Safety Council injuries from falls account for 20% of workplace injuries. In many cases, if you’re an employer, you could be liable for damages that can reach into the tens of thousands of dollars. Redwood Plastics offers three anti-slip plastic sheet materials which may help prevent injury. Redco “LUNS” is a UHMW based plastic sheet with a clean coal-slag surface. The surface is non-toxic and wears extremely well: the first application ever was as the floor of a US Navy tank carrier in 1989 – the floor is still in use and has not required replacement or significant maintenance!

Redco BRAXX is another, similar, product. Redco BRAXX is also UHMW based and is available in yellow with LUNS slag surface “buttons” and blue with sand buttons. Both products (BRAXX and LUNS) are available in just one size: 36″ x 108″ and 0.3″ thick. But what you can do with the product, besides using it in load bearing applications, is almost up to the imagination. Potential applications include:

-Subway/Bus stop curb top

-Stair treads

-Floor covering

-Boat deck surface

-Trailer bed cover

-Flooring top surface in wet environments

For answers to your questions on Redco LUNS or BRAXX’s anti-slip properties and suitability for your application, please contact us today.

We also can supply gritted, soft anti-slip interlocking matting for other applications. For details on that product click here.
