CHS pipe sizes follow specific standards and codes. For instance, in the United Kingdom, the British Standard (BS) 4360 outlines the preferred dimensions and tolerances for CHS. In the United States, the American Society for Testing and Materials (ASTM) provides specifications that are widely adopted, such as ASTM A500 for cold-formed steel structural tubing. Familiarity with these standards ensures that engineers and contractors select pipes that comply with local regulations and industry norms.

In 1845, a surgeon named Dr. Horace Day made the first crude surgical tape by combining India rubber, pine gum, turpentine, litharge (a yellow lead oxide), and turpentine extract of cayenne pepper and applying that mixture to strips of fabric. It was the first “rubber-based” adhesive and Dr. Day used it in his practice as a surgical plaster. Larger scale manufacturing of similar medical tapes began in 1874 by Robert Wood Johnson and George Seaburg in East Orange, NJ. That company would soon become the Johnson & Johnson Company we know today. Later in 1921, Earle Dickson who bought cotton for Johnson & Johnson noticed that the surgical tape kept falling off his wife Josephine’s fingers after cutting them in the kitchen. He fixed a piece of gauze to some cloth backed tape and the first Band-Aid ® was invented. It took almost 75 years from Dr. Day’s first crude tape until the early 1920’s when the first industrial tape application appeared. The application was electrical tape (although the adhesive was more of a cohesive film than the electrical tape we know today) to prevent wires from shorting. The second major industrial tape application was a result of the rise of the American automobile in the 1920’s. Two-toned automobiles were becoming popular and automakers needed a way to produce clean, sharp paint lines while using the new automatic paint spray gun. They started using the surgical tape that was available but the paint wicked through the cloth backing and caused defective paint jobs. Richard Drew, an engineer at Minnesota Mining and Manufacturing (3M) happened to be at a local body shop testing their WetorDry® brand sandpaper in 1925 and he saw the workers struggling to get clean paint lines. He went back to his lab and created a 2-inch wide crimp backed paper tape that became the first “masking tape” for painting. Jumping ahead to 1942 and World War II, Johnson & Johnson developed duct tape to seal canisters and repair equipment for the military. The tape was a basically a polyethylene coated cloth tape with good “quick stick” properties that made it easy to use in the field for emergency repairs. The world never looked back and duct tape can be found in almost any home or toolbox.

- Reasonable temperature resistance; between silicones (high resistance) and rubber (low resistance)
-
Most types of electrical tape have a maximum operating temperature between 80°C and 130°C.
- One of the main benefits of rubber tape is its flexibility and durability. Unlike traditional tapes, rubber tape is specially designed to withstand extreme temperatures, moisture, and UV exposure without deteriorating or losing its adhesive properties. This makes it ideal for outdoor and indoor use, as it can effectively seal leaks in a variety of surfaces such as metal, plastic, glass, and wood.
The Advantages of Silicone Self-Adhesive Tape
The Importance of Fire-Resistant Electrical Tape
Self-amalgamating tape is most commonly used to seal hoses, pipes and cables as well as to repair and protect them. It is particularly useful for protecting outdoor electrical joints in outdoor situations and, as mentioned above, it can protect sails from chafing in the marine industry. Plumbers will use self-amalgamating tape when fixing domestic leaks and car mechanics use it in radiator hose repairs. Closer to home, the tape is useful for adding more grip to sports equipment (racquets and bats), bicycle handles and much more!
Familiarize yourself with your area’s building codes. Select tapes that have been meticulously tested for reliability to ensure you’re getting tools that are worthy of your investment. It’s a good idea to opt for these tapes, too, as they are most likely to comply with building code.
Industrial Control Boxes
Electrical tapes are typically made with a polyvinylchloride (PVC) backing and a non-corrosive rubber-based adhesive. The backing is what gives it the ability to stretch and conform to cables and wiring. This stretch is a critical characteristic of electrical tapes because it allows the tape to wrap tightly around cables for long-lasting insulation. Most cloth, film, and other types of tapes do not possess the elongation characteristics that allow electrical tapes to function properly.
One of the key features of white PVC insulation tape is its flame-retardant properties. This quality is crucial when working with electrical systems, ensuring that the tape does not ignite easily, thus providing an additional layer of safety. Moreover, its flexibility and ability to stretch mean that it can be applied to irregular surfaces and shapes, making it an excellent choice for both intricate wiring jobs and larger repairs.
Conclusion
Split bolt connection. Protection of a split bolt connection begins with installing the connector and wrapping it with two layers of varnished cambric tape. Next, wrap the splice with four half-lapped layers of rubber or rubber mastic tape. Complete the job by over-wrapping with at least two half-lapped layers of premium vinyl electrical tape.
Double-Coated Polyethylene Foam Tape
The first commercial tape for electrical insulation was cotton friction tape, which became available in the early 1930s. Vinyl electrical tape was introduced in the mid 40s. This advanced material provided dramatic advantages over friction tape, including improved adhesion and moisture protection. Vinyl tapes have been refined substantially over the years, and other tape products have been added as well. Today's tapes offer long-term performance, excellent adhesion, and temperature resistance — not to mention smooth unwind from the roll. Resistance to adhesive transfer, superior conformability, high tensile strength, good elastic memory and recovery, and wider installation and operational temperature ranges characterize premium products.
The benefits of butyl rubber rolls extend beyond their physical properties. Their long lifespan and low maintenance requirements make them a cost-effective solution for various industries. By reducing the need for frequent replacements or repairs, businesses can allocate resources more efficiently.
In general, rubber based adhesives are not UV or oxidation resistant which is why they tend to be used predominantly in interior applications. Having said that, antioxidants and UV stabilizer packages can be added to the formulation to help mitigate these weaknesses. Some synthetic elastomers exhibit vastly improved UV stability over natural rubbers. Chemical resistance can also be problematic as is resistance to elevated service temperatures (typically 180- 200°F at the top end). The great strength of rubber-based adhesives is their wide formulation latitude. These adhesives can be compounded to be removable, repositionable, or extremely permanent. High strength foam bonding tapes can be made from rubber based adhesives or easily removable masking products can also be offered. Rubber based adhesive adhere to many surfaces including low surface energy plastics such as polypropylene and polyethylene. And to top it all off, rubber based adhesives are economical. They get the job done at a very fair price! Adhesive tapes made from rubber based adhesives have come a long way since Dr. Day’s first surgical tape and they still offer a cost-effective way to bond, seal, and protect.
