ASTM A312 TP304L Seamless Pipe High Pressure Sch40 for Power Plant

Power Plant Suitability of TP304L
TP304L seamless pipes excel in power generation due to ultra-low carbon content (<0.03%) preventing intergranular corrosion during welding and 400–550°C service. Their 18% Cr/8% Ni composition maintains oxidation resistance in boiler feedwater systems, while Sch40 heavy-wall design withstands 1,500+ psi steam pressure. Critical advantages include:

• Immunity to chloride stress corrosion cracking (SCC) in cooling water circuits

• Consistent toughness for thermal cycling in superheater headers

• PED/ASME B36.19 compliance eliminating post-weld heat treatment
  These properties ensure 100,000+ hour service life in coal/gas-fired plants, reducing unplanned outages by 40% versus carbon steel alternatives in condensate return systems.

SMLSCO Quality Control System:
Three-tier quality control:
① Raw material PMI verification
② Full-length ET + UT during production
③ 100% dimensional inspection with per-pipe photo documentation pre-shipment
All data is traceable with available SGS/TÜV third-party reports, ensuring consistent performance and stable quality across batches.

SMLSCO 304L Pipe Packaging Methods:
• LCL shipments: Plywood crates + end caps
• FCL shipments: Woven sacks with bundling + end caps
All wooden crates comply with automated US/EU warehouse requirements. Impact/moisture-proof packaging ensures transit safety, delivering shelf-ready products that eliminate customer reprocessing.
