Stainless Steel High Pressure Pipe 0.5in Wall, API 5LC,
Erosion-Resistant, Oil Drilling
Stainless Steel High-Pressure Pipes (0.5in Wall Thickness) by Jiangsu China Steel Union Industrial Co., Ltd are engineered for extreme oil and gas drilling operations,
offering unmatched erosion and corrosion resistance in abrasive,
high-pressure downhole environments. Compliant with API 5LC, these pipes combine high-strength stainless steel with a 0.5in
(12.7mm) wall thickness to withstand sand-laden drilling fluids,
H₂S sour gas, and acidic wellbore conditions. The seamless
manufacturing process ensures structural integrity under pressures
exceeding 10,000 psi, while chromium (16–18%) and molybdenum (2–3%) content provide
superior resistance to pitting and sulfide stress cracking (SSC).
Ideal for directional drilling, fracking, and deepwater
exploration, these pipes are designed for longevity in the harshest
oilfield applications.

and DNV-GL certification for offshore use.
- Custom Solutions: API threading (BTC, LTC), upset ends, and internal/external
coatings (Ni-P or Cr-C) for corrosive wells.
4. Key Applications
- Directional Drilling: Heavy-weight drill pipes (HWDP) and bottom-hole assemblies (BHA)
in abrasive formations.
- Hydraulic Fracturing: High-pressure frac lines and zipper manifolds for shale gas
extraction.
- Sour Gas Wells: Casing and tubing for H₂S-rich reservoirs, compliant with NACE
MR0175 standards.
- Offshore Rigs: Riser systems, choke/kill lines, and subsea Christmas tree
components.
- Enhanced Oil Recovery (EOR): CO₂ injection lines and steam-assisted gravity drainage (SAGD)
pipelines.
