Easiest way to connect lead to copper /brass is a wiped joint consisting 40 - 60 solder alloy as this gives a longer pasty range
When I have to connect copper to lead "D" I usually solder the copper to the lead or wipe a lead joint depending on the diameter To connect copper to cast iron ,.... If there is a hub I caulk the copper directly into the CI with oakum and poured lead (molten) OR one can solder / braze a female adapter fitting and screw the copper into a CI female fitting
To make a lead or copper pipe all you need is sheet copper/ lead and either lead wipe /solder /braze the end or if copper use a Pittsburg found in sheet metal shops to make the seam
Use a lead-free silver solder. It is the only thing that can handle the pressure and bond with the copper pipe.
For copper pipe, lead-free solder is recommended to ensure safe and effective connections.
A dehumidifier is a device for the removal of moisture from the air. The copper pipe that is not connected is almost certainly a drain pipe. As the dehumidifier removes moisture from the air, it has to collect and then drain in some way. A drain pipe would handle the latter chore. Consult the manufacturer or a distributor for a manual or just some information.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
YES there is
tig or mig depending on the wall thicknessCopper to copper is either soft soldered, or silver solderedSilver solder is a bad term as "solder" normally means lead content according to the AWS
To connect copper to PEX pipes, you can use a fitting called a PEX-to-copper adapter. This adapter typically has a PEX side that can be crimped onto the PEX pipe and a copper side that can be soldered or connected using a compression fitting to the copper pipe. Make sure to follow the manufacturer's instructions and use the appropriate tools for a secure and leak-free connection.
I am sorry, but can you PLEASE rephrase your question? Can WHAT be used for copper pipe? When? How? Why?
Grooved method? Threads on the end of the pipe? There is no tube or pipe in copper with threads. You can end a copper pipe with a connection that is threaded to accept steel pipe.
The melting point of copper is approximately 1,984°F (1,085°C), but this can vary slightly depending on the specific composition of the copper alloy used in the pipe. It is important to note that the melting point of copper pipe should never be reached during regular use, as it could lead to structural failure and potential safety hazards.
