Product Advantages
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. Frequently Asked Questions Q1: Do SMLSCO's WP347 90-degree elbows comply with European market
access standards? A1: Absolutely. Our fittings hold PED 2014/68/EU and AD2000
certifications. For high-performance materials like WP347, we
strictly adhere to ASTM A403 standards to ensure seamless entry
into high-end global industrial projects. Q2: What is the standard lead time for a 4-inch elbow? A2: Thanks to our 200-ton inventory, common wall thicknesses from
Sch 10s to Sch 160 are typically in stock. Following 100%
pre-shipment inspection, we complete labeling, packaging, and
dispatch within 2 weeks. Q3: How do you guarantee the safety of WP347 fittings in
high-pressure environments? A3: All SMLSCO WP347 elbows are manufactured strictly according to
ASME B16.9. Seamless fittings undergo rigorous non-destructive
testing (NDT), while welded types receive 100% RT (radiographic
testing) to ensure weld strength matches base material
specifications. |
