2. PPGI - Wikipedia

   en.wikipedia.org/wiki/PPGI

   However, only "pure" zinc coated steel is typically referred to as PPGI. For example, PPGL may be used for pre-painted 55%Al/Zn alloy-coated steel (pre-painted GALVALUME(r) steel*) Over 30 million tons of such coated steel is produced today in over 300 coating lines just in Boxing which is a little county in North of China.

3. Hot-dip galvanization - Wikipedia

   en.wikipedia.org/wiki/Hot-dip_galvanization

   Galvanized fumes are released when the galvanized metal reaches a certain temperature. This temperature varies by the galvanization process used. In long-term, continuous exposure, the recommended maximum temperature for hot-dip galvanized steel is 200 °C (392 °F), according to the American Galvanizers Association.

4. Galvanization - Wikipedia

   The life expectancy of galvanized piping is about 40–50 years, [12] but it may vary on how well the pipes were built and installed. Pipe longevity also depends on the thickness of zinc in the original galvanizing, which ranges on a scale from G01 to G360.

5. ASTM A53 steel - Wikipedia

   en.wikipedia.org/wiki/ASTM_A53_steel

   Scope of ASTM A53 Standard ASTM A53 is standard specification for pipe, steel, black and hot dipped, zinc-coated, welded and seamless. This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1⁄8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 ...

6. Corrugated galvanised iron - Wikipedia

   en.wikipedia.org/wiki/Corrugated_galvanised_iron

   Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

7. Pipe (fluid conveyance) - Wikipedia

   en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

   The number system, like Sch 40, 80, 160, were set long ago and seem a little odd. For example, Sch 20 pipe is even thinner than Sch 40, but same OD. And while these pipes are based on old steel pipe sizes, there is other pipe, like cpvc for heated water, that uses pipe sizes, inside and out, based on old copper pipe size standards instead of steel.

8. Piping and plumbing fitting - Wikipedia

   en.wikipedia.org/wiki/Piping_and_plumbing_fitting

   A galvanized coating of metallic zinc was often used to protect steel water pipes from corrosion, but this protective coating eventually would dissolve away, exposing the iron to deterioration. Pipes used to convey fuel gas are often made of "black iron", which has been chemically treated to reduce corrosion, but this treatment does not resist ...

9. Lead service line - Wikipedia

   en.wikipedia.org/wiki/Lead_service_line

   As of March 2019, contractors excavated 21,000 sites, they found and replaced 8,000 lead or galvanized steel service lines. A computer model was used to identify the next batch of excavations. It is estimated that 2,500 more lead or galvanized steel service lines will be found and replaced. [48] United States: Framingham, Massachusetts: 15: ...
