1. What are galvanized pipes?
Galvanized pipes are steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust. Galvanized piping was commonly installed in homes built before 1960. When it was invented, galvanized pipe was an alternative to lead pipe for water supply lines. Today, however, we have learned that decades of exposure to water will cause galvanized pipes to corrode and rust on the inside.
2. Galvanized seamless pipe is divided into cold-plated steel seamless pipe and hot dip seamless pipe.
Hot paglangoy magkatugmang pipe
Ang tuluy-tuloy na pipe ay upang gawin ang tunaw metal at bakal substrate reaksyon, ang haluang metal layer, sa gayon na ang substrate at coating kumbinasyon ng pareho. Hot-lumangoy galvanizing ay ang unang bakal pag-aatsara, upang alisin ang bakal pipe ibabaw ng bakal oksido, pag-aatsara, may tubig solusyon ng ammonium klorido o sink klorido o ammonium klorido at sink klorido halo-halong may tubig solusyon tank cleaning, at pagkatapos ay ipadala sa mainit dip tank. Hot lumangoy galvanized patong pagkakapareho, malakas na pagdirikit, at mahabang buhay.
Cold-tubog magkatugmang pipe
Cold galvanized, electric-yero, yero ang dami ng mga maliliit na, lamang 10-50g / m2 ng kanyang sarili na pagtutol sa kaagnasan kaysa sa hot lumangoy galvanized pipe ng maraming pagkakaiba. Regular yero tagagawa pipe, upang matiyak ang kalidad, karamihan huwag gumamit ng electric-galvanized (cold-tubog). Tanging ang mga maliliit na-scale, hindi napapanahong kagamitan at mga maliliit na negosyo na may electric yero, siyempre, ang kanilang mga presyo ay medyo mura. Ang Ministry of Construction ay pormal ibaba, malamig galvanized pipe upang maalis paatras teknolohiya, ang hinaharap ay hindi pinapayagang malamig na galvanized pipe para sa tubig, pipe gas.
3. Galvanized seamless mechanical properties
Ang mekanikal katangian ng bakal ay upang matiyak na ang isang mahalagang tagapagpahiwatig ng ang bakal properties end-use (mechanical properties), ito ay depende sa chemical komposisyon at init paggamot ng bakal. Steel pamantayan, ayon sa iba't ibang mga kinakailangan, ang mga probisyon ng ang mga katangian makunat (makunat lakas, ani lakas o ani punto pagpahaba) at tigas, kayamutan, kinakailangan ng gumagamit, mataas at mababang pagganap temperatura.
4. How long do galvanized pipes last?
No piping system lasts forever, but galvanized pipes have a life span of between 40 to 100 years. If your home’s pipes are from the 1960s or earlier, they are likely nearing the end of their functional life span. However, there’s a reason galvanized pipes are no longer used in modern construction: the risk they pose to a home’s water supply and people’s health.
5. Are there safety risks or concerns with galvanized piping?
By far, the most significant problem related to galvanized pipes is the mineral deposits that accumulate within the piping. Over time, it causes a reduction in water pressure and pollutes your home’s water. And as rust and corrosion deepen, they compromise the piping system’s stability and cause leaks.
As old and corroded galvanized pipes age, they can release accumulated lead into your tap water. That lead can pose significant health concerns, as ingesting too much can result in lead poisoning, and its symptoms include fatigue, headaches, insomnia, nausea, constipation, abdominal pain, and reduced cognitive abilities. High doses of lead are of particular concern with children, as it can hinder their brain development and lead to lifelong health issues.

Ibabaw ng kalagayan ng yero tubes
First layer –electrically leached zinc (Zn) – acts as anode and in a corrosive environment it corrodes first and the base metal is cathadically protected against corrosion. The zinc layer thickness may be in the range of 5 to 30 micrometers (µm).
