Description
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?
SMLSCO maintains 2000 tons of TP304L pipe year-round (Sch5s – XXS), with standard specifications shippable within two weeks. Centralized procurement of high-alloy billets and scaled cold-drawing processes optimize cost efficiency – empowering distributors with dual competitive edge in pricing and lead time for high-corrosion applications.

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.
