Description

​1541 Grade Drilling Pipe – Simple, Strong & Affordable​​
Need a ​​reliable, budget-friendly drilling pipe​​ for standard wells? 1541 grade is your go-to.

​​Why It Works​​
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

​​Applications include mine blasting, water well drilling, geothermal well drilling, fore poling (advance support), and coal and nonferrous metal mining.​
