1. Introduction
ASTM A269 is a common industry standard for stainless steel tubes.
Our ASTM A269 seamless steel pipes have no weld lines. They have even wall thickness and good pressure resistance.
They stop liquid leak and slow down rust. They fit well for liquid transport, heat exchange and simple instrument use.
2. Standard Basic Info
- Product: Seamless & welded stainless steel tube
- Min inner size: 6.4mm, min wall thickness: 0.51mm
- Made by hot rolling or cold drawing, with standard heat treatment
- All goods pass strict defect checks before delivery

4. Basic Physical Strength
- Pull strength: Over 515 MPa
- Yield strength: Over 205 MPa
- Stretch rate: Over 35%
- Hardness: Below 200 HB
The pipes are strong and easy to bend for installation.
5. Main Advantages
1.No weld seam, safe to use under high pressure
2.Resist rust, acid and salt, long service time
3.Work well in very cold and high heat places
4.Exact size, easy to match other pipe parts
6. Common Usage
- Chemical factory: Move corrosive liquid
- Heating equipment: Heat exchange pipes
- Machine parts: Small hydraulic and air pipes
- Food and medicine: Clean fluid delivery
- Sea project: Anti-rust marine pipes
- Power plant: High temperature auxiliary pipes
7. Factory Quality Check
We test all pipes strictly:
- Check material content
- Test physical strength
- Do water pressure and air tight test
- Use machine to find inner cracks
- Check size and surface condition
8. Simple Difference: A269 VS A312
- ASTM A269: Thin wall pipe, for daily general use
- ASTM A312: Thick wall pipe, for high pressure heavy work
9. Easy Buying Tips
- Choose TP304 for normal use; choose TP316L for bad working places
- Mark size as outer diameter * wall thickness * length
- Ask for factory test report when placing order
- Choose plain white pickled or bright polished surface
10. Summary
ASTM A269 seamless stainless steel pipe is cheap and reliable.
It has good anti-rust ability and exact size. It can meet most common industrial pipe needs.

Simple FAQ
Q1: Can it be used for food delivery?
A1: Yes. Polished 304 and 316L type are safe for food use.
Q2: How much pressure can it take?
A2: 10 to 40 MPa, based on different wall thickness.
Q3: Can you make custom sizes?
A3: Yes. We can change pipe size, length and surface finish.
