What This Sector Is Up Against

Water systems are long life assets where the pipe is buried, embedded or hidden in a riser, so replacement cost far exceeds material cost. Stainless is specified here for drinking water quality, for sprinkler reliability and for drainage that has to survive decades.

Pain Points

  • Secondary contamination of purified water in the distribution network
  • Corrosion in drainage and wastewater lines carrying aggressive effluent
  • Sprinkler systems that must work after years of standing water
  • Irrigation water chemistry attacking coated carbon steel

What Buyers Need

  • Pipe that will not contaminate drinking water in the riser
  • Corrosion resistant structural sections for tanks and launders
  • Welded and seamless options across a wide diameter range
  • Long lengths to reduce the number of buried joints

Typical Application Scenarios

  • Water supply and drainage mains and irrigation systems
  • Direct drinking water distribution from building purification stations
  • Fixed fire sprinkler piping
  • Water and wastewater treatment tank frames in 316 angle bar

Delivery Terms for This Sector

  • Lengths to 12000 mm on the 304 and 316L pipe programmes
  • Stock fittings in 7 days and non stock in 15 days
  • Packing in woven bags, wooden cases or to your specification
How an order runs

From Enquiry to Container

  1. Step 1

    Match the grade to the water chemistry and the chloride level

  2. Step 2

    Select welded or seamless according to pressure and buried service

  3. Step 3

    Order long lengths to cut the number of joints

  4. Step 4

    Supply matching elbows and tees so the run completes in one delivery

  5. Step 5

    Pack and ship with the mill test certificate

FAQ

Water and Fire Protection Questions

Why use stainless pipe for direct drinking water
Purification stations feed an independent circulating network, and stainless pipe carries the purified water to the user without the secondary pollution that other pipe materials can introduce.
Is stainless used in fire protection systems
Yes. Stainless fire fighting piping is a fixed fire protection facility widely used in China, working with the automatic alarm mechanism so a sprinkler system can control an initial fire.
Which grade suits wastewater service
316L where chlorides and aggressive effluent are present, and 304 where the duty is milder. For structural frames inside a wet plant, 316 angle bar resists chloride pitting that painted carbon steel does not.
Can you supply 6 m and 12 m lengths
Yes. The 304 and 316L pipe programmes run from 1000 mm up to 12000 mm.
Do you supply angle bar for tank structures
Yes. 316 equal angle bar is produced at 75 x 75 x 6 mm with thickness held to plus minus 0.02 mm, in 6 m lengths or cut as requested.
