Q&A about Copper: Products, Construction, Processing, Surface Treatment
Advice on preventing and addressing issues related to the use of brass and bronze fittings, as well as measures to prevent and mitigate discoloration phenomena, is also included!
On the Japan Copper Center's website, we have published a Q&A regarding copper related to "products, construction, processing, and surface treatment." We introduce topics such as, "We use 15.88 insulated copper pipes for hot water heater piping, but are the water piping and air conditioning refrigerant copper pipes the same?" Additionally, we provide answers to questions like "What points should be noted when connecting existing galvanized steel pipes to copper pipes during water heater replacement?" and "Why does a 10-yen coin become clean due to the acidity of cola?" 【Published Q&A (excerpt)】 ■ We use 15.88 insulated copper pipes for hot water heater piping, but are the water piping and air conditioning refrigerant copper pipes the same? ■ What points should be noted when connecting existing galvanized steel pipes to copper pipes? ■ When bending 1/2 copper pipes using a bender, an internal pressure of 2.9 MPa is applied; is the strength okay? ■ If green rust occurs due to the influence of flux during construction, does it mean poor workmanship? *For more details, please feel free to contact us.
