Solar galvanized pipe connection method China

How to connect galvanized steel pipes?

Galvanized steel pipes should be connected with threads. The surface of the galvanized layer and the exposed threaded parts that are damaged when threading the threads should be treated with anti-corrosion. Flanges or ferrule-type special pipe fittings should be used for connection.

What are the different types of pipe connection methods?

Depending on the purpose and pipe material, commonly used connection methods for the construction of steel pipes include threaded connection, flange connection, welding, groove connection (clamp connection), ferrule connection, compression connection, hot melt connection, socket connection, etc. 1.

How are solar pipes dimensioned?

This expansion in length must be taken into account through appropriate fastening (compensators) and the installation of expansion bends or bendable joints in the pipe. Solar pipes are dimensioned in the same way as heating pipes.

How to choose a hot water storage tank for a solar circuit?

Suitable materials for the pipes of the solar circuit offer: the necessary weathering and corrosion resistance for outdoor use (no galvanised pipes). The hot water storage tank should have a volume of 1.5 to 2 times the daily consumption of hot water per person, i.e. about 100 litres per person, to store hot water for days with less radiation.

How do you crimp a steel pipe?

Card sleeve connection: Aluminum-plastic composite pipes generally use threaded clamp sleeves for crimping. Put the fitting nut on the end of the steel pipe, then put the inner core of the fitting into the end, and use a wrench to tighten the fitting and nut. Copper pipes can also be connected using threaded ferrules.

How to connect copper pipes?

Special joints or welding can be used to connect copper pipes. When the pipe diameter is less than 22mm, socket or casing welding should be used. The socket should be installed against the flow direction of the medium. When the pipe diameter is greater than or equal to 2mm, butt welding should be used.
