Caulk (also known as caulking and calking) [1] is a material used to seal joints or seams against leakage in various structures and piping. The oldest form of caulk consisted of fibrous materials driven into the wedge-shaped seams between boards on wooden boats or ships. Cast iron sewerage pipes were formerly caulked in
The joint is then heated, typically by using a propane or MAPP gas torch, although electrically heated soldering tools are sometimes used. Once the fitting and pipe have reached sufficient temperature, solder is applied to the heated joint, and the molten solder is drawn into the joint by capillary action as the flux vaporizes. "Sweating" is a ...
In Section 17 states: "All Joints in cast Iron soil pipe shall be packed with picked oakum and run with molten lead well caulked. All connections of lead with iron pipe must be made with a brass ferrule of the same size as the lead pipe and caulked into the iron pipe as specified for cast iron pipe and connected to with the lead pipe with a ...
Thread seal tape used in plumbing applications is most commonly white, but it is also available in various colors. It is often used to correspond to color coded pipelines (US, Canada, Australia, and New Zealand: yellow for natural gas, green for oxygen, etc.). These color-codes for thread sealing tape were introduced by Bill Bentley of Unasco ...
A compression fitting 15 mm isolating valve. A compression fitting is a fitting used in plumbing and electrical conduit systems to join two tubes or thin-walled pipes together. . In instances where two pipes made of dissimilar materials are to be joined (most commonly PVC and copper), the fittings will be made of one or more compatible materials appropriate for the connect
Wiped joints were used for centuries to install water plumbing and similar joints can be seen in Roman plumbing. [3] As the wiping technique allowed a great deal of on-site flexibility for the style and dimensions of the work produced, this meant that plumbers needed few parts other than pipe, lead sheet and solder.
Shortly thereafter, the Victory Pipe Joint Co. was established in London, England and a second patent was filed in both names. Dr Hele-Shaw had numerous inventions including the multiple-plate clutch, stream-line filter, variable-pitch propeller, and Victaulic pipe joint. [12] Victaulic fittings were used in tunnels, ship work, and borings.
To obtain functional joints, the inside of the fitting and the outside of the copper pipe are cleaned using steel wool or cleaning tape, flux paste is applied, the pipe is inserted into the fitting and heat is applied from a portable butane torch or propane torch until a ring of solder shows at the edges of the fitting. To obtain a durable ...
