Products Description

Our American Spiral Steel Pipe is fully up to American standards-ASTM A252, API 5L, and ASTM A139, all the ones that matter for your business.

The spiral welding process here has a big advantage: it spreads stress evenly, so the pipe's way more durable than regular ones.

Made with high-grade carbon steel, it resists corrosion, handles high pressure, and even stands up to extreme weather-super reliable for all kinds of jobs.

We've got every size you might need as a wholesaler: diameters from NPS 8 to NPS 100 mm, wall thicknesses from SCH 10 to SCH 160, and lengths from 1 to 30 meters. Every single American Spiral Steel Pipe also comes with a factory test report, so you can show your clients it's up to snuff.

Factory Processing

When we make American Spiral Steel Pipe, we focus on keeping things consistent and cutting down on defects-we know how important that is for your stock.

First, we unwind the steel coil, flatten it out, then cut it to the exact width we need. After that, our automated machines shape it into that spiral form you're after.

Next, we use submerged arc welding (SAW) to seal the weld-it's a solid method that meets API 5L standards. Once welding's done, every American Spiral Steel Pipe goes through 100% ultrasonic testing (UT) to check for internal flaws, plus a hydrostatic test to make sure it's leak-free.

If you need a specific surface treatment, we've got you covered: hot-dip galvanizing, painting, non-toxic coating for drinking water, PE coating, sandblasting for rust removal-whatever your clients need.

Finally, we stick a label on each pipe with its size, grade, batch number, and heat code, so you can keep your inventory organized easily.

Production Capacity

We've got six fully automated spiral steel pipe production lines, and they handle American Spiral Steel Pipe in sizes from NPS 8 to NPS 100.

All together, we can make up to 3,600 tons of these pipes every month-plenty to cover your wholesale orders.

We also keep common sizes in stock, so you don't have to wait around for standard orders. Our factory has ISO 9001 and API 5L certifications-total must-haves for doing business with clients in industries like oil and gas. And we get audited by BV every year, so you know we're sticking to the rules.
