Copper tube soldering tin
Are you interested in soldering copper pipes with tin from the supplier company AvecGlob? Here you will find the necessary information on this topic.
Scope of the process
Soldering copper pipes with tin is most often found in the repair or modernization of plumbing systems for individual use. For success, you need to properly use the possibilities of tin as the main consumable.
Choice of solder
For drinking water systems, it is necessary to use tin grades, which contain no lead. Usually this is 95/5 (95% tin and 5% antimony) or a tin alloy and a small amount of copper and / or silver.
Preparation of flux
Zinc chloride or rosin is usually used to clean and prepare the surface of a copper pipe. They complete the coating of the cleaned surfaces of the copper pipe before assembling and heating it. It is the stream function when heated that facilitates further purification, eliminates oxygen in the atmosphere, prevents re-oxidation and helps with the wetting of the solder.
Selecting a soldering iron
Typically, a traditional electric soldering iron will not be hot enough to work with copper pipes. A heat source of sufficient output power is required to heat the assembled fittings and tubing to a temperature above the required one. This is necessary in order to completely melt the filler, usually it requires a temperature of 200… 260 ° C. For this reason, the heat source is a propane / air cutter or acetylene / air, equipped with a tip of the appropriate size. To apply the necessary soldering materials to the soldering zone, clean, dry cotton rags and a can of water are used.
Supplier — AvekGlob Company — offers various types of products from tin of domestic and foreign production, which meets the requirements of standards. The products are offered at affordable prices from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Preparation of a copper pipe for soldering
In the bonding area, there should be no trace of oxide films. To do this, you can use sandpaper, emery cloth or special devices. All copper oxides must be carefully removed from both surfaces until they are completely clean, free of dirt, grease, oil, or other obstructions that will interfere with the wetting of the solder, which will lead to the leakage of the fitting.
The cleaned surfaces are treated with tin solder, after which it is necessary to assemble the fitting and the pipeline as soon as possible. The flux is applied inside and outside the copper tube.
Soldering
Light the torch and adjust it so that the flame is blue. Move the torch in the direction. The opposite length of the fitting, moving it around the components in the area that needs to be welded. The flame is used to heat and melt the solder. Then the flame is touched to the joint. The heated pipe will draw molten solder into the joint by capillary action. When moving the flame in the opposite direction, a small amount of solder is constantly fed. and move the torch until the solder completely covers the fitting.
Overheating of copper is inadmissible, in this case, copper darkens, and such a fitting will not be sealed. The connection should be disassembled and the process repeated. The joint site is checked for leaks and cooled.
Supplier — AvekGlob Company — offers to purchase tin in a wide range of profiles and technological applications. Products can be bought at a price formed on the basis of European and world standards. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
