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.

celup panas paip lancar

Paip yang lancar adalah untuk membuat tindak balas logam dan besi substrat lebur, lapisan aloi, supaya substrat dan lapisan gabungan kedua-duanya. Hot-dip galvanizing adalah penjerukan keluli yang pertama, dalam usaha untuk menghapuskan permukaan paip keluli oksida besi, penjerukan, larutan ammonium klorida atau zink klorida atau ammonium klorida dan zink klorida campuran larutan pembersihan tangki, dan kemudian menghantar ke dalam panas tangki berenang. Hot dip salutan tergalvani keseragaman, melekat kuat, dan sepanjang hayat.

lancar paip sejuk saduran

Sejuk Tergalvani, elektrik Tergalvani, galvanized jumlah kecil, hanya 10-50g / m2 rintangan sendiri kakisan daripada tergalvani panas paip banyak perbezaan. Biasa pengeluar paip bergalvani, untuk memastikan kualiti, paling tidak menggunakan elektrik galvanized (sejuk saduran). Hanya mereka kecil, peralatan ketinggalan zaman dan perniagaan kecil dengan elektrik Tergalvani, sudah tentu, harga mereka adalah agak murah. Kementerian Pembinaan mempunyai secara rasmi di bawah, paip bergalvani sejuk untuk menghapuskan mundur teknologi, masa depan tidak akan dibenarkan untuk paip bergalvani sejuk untuk air, paip gas.

 

3. Galvanized seamless mechanical properties

Sifat-sifat mekanikal keluli adalah untuk memastikan bahawa penunjuk penting keluli penggunaan akhir hartanah (sifat-sifat mekanikal), ia bergantung kepada komposisi kimia dan haba rawatan keluli. standard keluli, mengikut keperluan yang berbeza, peruntukan sifat tegangan (kekuatan tegangan, kekuatan alah atau titik alah pemanjangan) dan kekerasan, kekuatan, keperluan pengguna, prestasi 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.
