The Workhorse Pipe You Can Build On
We’ve been producing ASTM A53 Grade B pipes for over 15 years, and we still get excited about them. Why? Because they’re the unsung heroes of carbon steel piping – tough enough for oil rigs, precise enough for chemical plants, and reliable enough that engineers keep coming back.
What makes Grade B special? The 35,000 psi minimum yield strength and 60,000 psi tensile strength hit that sweet spot between durability and workability. We see it used everywhere from offshore platforms to municipal water systems. The welded ERW/EFW versions make economic sense for larger diameters (we’ve supplied up to 48″), while seamless pipes (hot-finished or cold-drawn) are preferred for high-pressure steam lines and hydraulic systems where wall consistency is critical.
Where Performance Meets Practicality
- Our seamless pipes cover NPS 1/8″ to 26″ with wall thickness from SCH 10 to SCH 160 – that’s why power plants trust them for high-temp applications
- The welded versions use double-submerged arc welding for critical projects, with X-ray inspection available
- Every pipe gets hydrostatic tested at pressures exceeding working requirements (we’ve seen some hold at 3,000 psi!)
- The chemical composition (≤0.30% C, ≤1.20% Mn) gives you excellent weldability without preheating in most cases
One customer in the Gulf used our galvanized A53 pipes for a coastal refinery project – after 5 years, they reported zero corrosion-related maintenance. That’s the kind of real-world performance we build for.
Made in China, Built for Your Needs
Being a factory-direct supplier means we control everything:
– Custom lengths (from 5.8m to 12m standard, but we’ve done 16m specials)
– End treatments from plain to threaded-and-coupled (we keep NPT threads in stock)
– Special coatings like 3LPE or FBE for harsh environments
– Third-party inspection (SGS, BV, etc.) with full documentation
We don’t just cut pipes to size – we help solve problems. Need a 14″ OD with non-standard wall thickness? Done. Pipes for high-sulfur gas service? We’ll tweak the sulfur content below the standard 0.045% max. Our ISO 9001-certified process means you get consistency, whether it’s 10 pipes or 10,000.
When you need carbon steel pipes that balance strength, availability, and cost, we’re here to help. Give us your specs – we’ll make it work.
