Galvanized Steel Pipe

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 dip pipa seamless

The pipa seamless adalah untuk membuat reaksi logam dan besi substrat cair, lapisan paduan, sehingga substrat dan lapisan kombinasi keduanya. Hot-dip galvanizing adalah pengawetan baja pertama, dalam rangka untuk menghapus permukaan pipa baja dari besi oksida, pengawetan, larutan amonium klorida atau seng klorida atau amonium klorida dan seng klorida campuran tangki larutan pembersih, dan kemudian mengirim ke panas tangki dip. Hot dip coating galvanis keseragaman, adhesi yang kuat, dan umur panjang.

pipa seamless dingin berlapis

Dingin galvanis, listrik-galvanis, galvanis jumlah kecil, hanya 10-50g / m2 resistensi sendiri terhadap korosi dari hot dip galvanis pipa banyak perbedaan. Regular produsen pipa galvanis, dalam rangka untuk memastikan kualitas, paling tidak menggunakan listrik-galvanis (dingin berlapis). Hanya mereka skala kecil, peralatan usang dan usaha kecil dengan listrik galvanis, tentu saja, harga mereka relatif murah. Kementerian Konstruksi memiliki secara resmi di bawah ini, pipa galvanis dingin untuk menghilangkan mundur teknologi, masa depan tidak diperbolehkan untuk pipa galvanis dingin untuk air, pipa gas.

 

3. Galvanized seamless mechanical properties

Sifat mekanik baja adalah untuk memastikan bahwa indikator penting dari sifat penggunaan akhir baja (sifat mekanik), itu tergantung pada komposisi kimia dan perlakuan panas baja. standar baja, sesuai dengan kebutuhan yang berbeda, ketentuan sifat tarik (kekuatan tarik, kekuatan luluh atau titik luluh elongasi) dan kekerasan, ketangguhan, kebutuhan pengguna, kinerja suhu tinggi dan rendah.

 

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.
