ASTM A312 TP304L Seamless Pipe High Pressure Sch40 for Power Plant
Material Properties
TP304L features ultra-low carbon design to significantly enhance
intergranular corrosion resistance. Its high Cr-Ni content
maintains strength and toughness during continuous operation above
400°C. The heavy-wall Sch40 construction provides higher pressure
tolerance, safely withstanding chloride corrosion and thermal
cycling in power plant steam and high-pressure feedwater systems.
Why Choose SMLSCO Pipe Stock?

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.
