Product Q&A

Q:Difference between hot-dip galvanized and black pipe?

1) Surface: Hot-dip galvanized pipe has silver-white zinc layer, black pipe surface is black scale; 2) Anti-corrosion: Hot-dip galvanized pipe 20-30 year life, black pipe no anti-corrosion (outdoor 1-2 years rust); 3) Price: Hot-dip galvanized pipe RMB 800-1200/tonne more expensive than black (galvanizing fee);

Q:Can hot-dip galvanized pipe be welded?

Yes, but not recommended. Welding damages zinc layer in welding area, produces zinc fumes (toxic), and welded area prone to rust. If must weld: 1) Remove zinc layer in welding area before welding (grinding); 2) Strengthen ventilation during welding, avoid inhaling zinc fumes;

Q:How to test hot-dip galvanized pipe zinc coating thickness?

Hot-dip galvanized pipe zinc coating thickness tested with magnetic thickness gauge (non-destructive), test multiple points on pipe surface and take average. GB/T 13912 specifies: pipe thickness >=6mm, average zinc coating >=85um, local >=70um; pipe thickness <6mm, average >=65um, local >=55um.

Q:What are hot-dip galvanized pipe connection methods?

1) Threaded connection: Threaded then fittings (elbows, tees, flanges etc.), suitable for DN15-DN100, detachable, standard connection for water supply/drainage and fire; 2) Grooved connection: Roll grooved then clamp connection, quick installation, detachable, suitable for DN65-DN200 fire and water supply/drainage;

Q:MOQ and lead time?

Stock from 1 pipe 3-7 days, common sizes same-day pickup; special sizes and custom lengths from 5 tonnes 7-15 days. Cutting, threading, grooving, welding flanges etc. fabrication services available.
