Need a reliable, budget-friendly drilling pipe for standard wells? 1541 grade is your go-to.
1. Solid Strength – Handles wells up to 3,000m with 800–950 MPa tensile strength – enough for most jobs.
2. Tough Enough – 16% elongation absorbs minor shocks (like tripping or rotation) without breaking.
3. Easy to Weld – No special prep needed – just weld and go.
4. Wears Well – Better than basic carbon steel, great for soft to medium rock (sandstone, shale).
5. Low Cost – No fancy alloys – just affordable performance for everyday drilling.
Perfect For:
Shallow to mid-depth wells (≤3,000m)
Stable formations (low abrasion)
Projects watching costs
