45° Sanitary Welded Elbow
SDFL
Our 45 degree sanitary welded elbow is a hygienic pipe fitting for changing fluid direction at 45° in sanitary pipeline systems. Made of 304 / 316L stainless steel with mirror internal & external polishing, it eliminates dead corners, avoids material residue and bacterial growth. It complies with DIN11850 and ASTM A270 standards, widely used for food, dairy, beverage, brewery and pharmaceutical fluid transfer pipelines.

In-house manufacturing with a mandrel cold push forming line and polishing equipment supports controlled lead times.
100% PMI spectral inspection per batch, traceable to the mill heat number, verifies material identity.
Dual product lines for industrial heavy-duty and sanitary high-purity fittings allow one supplier for both systems.
Special alloy processing for corrosion and high-temperature conditions supports demanding media.
Seamless one-piece forming with uniform wall thickness is compatible with orbital welding.
Production to international standards with documented certifications simplifies compliance review.
Mechanical, mirror and electropolishing options match specified cleanliness levels.
Raw tube PMI and dimension inspection → precision cutting and sizing → mandrel cold push forming → end trimming and beveling → internal and external polishing → degreasing and high-purity cleaning → dimensional and surface inspection → final QC (size, roughness, leakage test) → clean packaging.
