Inventory Strength: 200 tons of fittings in stock, covering full specifications from 1/8" to 4", meeting urgent replenishment needs
Fast Delivery: Standard specifications shipped within 2 weeks using bulk raw material reserves and efficient production lines
Comprehensive Certifications: PED and AD2000 certifications meet European and North American market access requirements
Cost Efficiency: Competitive pricing through large-scale procurement from top-tier suppliers without compromising quality
Full Traceability: Unique identifiers support full-process data queries from raw material to final inspection
Zero-Defect Quality Promise
SMLSCO employs a rigorous "3-Step Inspection" system ensuring every WP347 elbow meets international standards. From PMI chemical analysis of raw materials to production monitoring and 100% final inspection, we maintain comprehensive quality control. All welded fittings undergo strict X-ray testing (RT), with archived test documentation supporting third-party inspections by SGS and TUV.
Packaging Methods
Customized protection solutions for different logistics scenarios. LCL shipments use high-strength plywood cases with internal plastic bags to prevent surface damage. FCL shipments implement tiered protection: fittings under 12 inches in plywood cases, larger diameters secured on pallets with multiple plastic film layers to ensure perfect condition upon arrival.
Material Properties
WP347 is a stabilized austenitic stainless steel with enhanced intergranular corrosion resistance due to niobium (Nb) addition. It performs exceptionally in sensitization temperature ranges (427°C to 816°C) and offers superior creep and stress rupture properties compared to 304 or 321 grades. Ideal for demanding applications in oil refining, power generation, and energy sectors, extending pipeline system life and reducing maintenance costs.
