Product Description
Custom Size Pickled Passivated Stainless Steel Butt Weld Pipe Tee ISO 9001
Custom Size Pickled Passivated Stainless Steel Butt Weld Pipe Tee ISO 9001 Certified

The Custom Size Pickled Passivated Stainless Steel Butt Weld Pipe Tee combines flexible dimensional customization with professional surface treatment to meet specialized project requirements. Manufactured under an ISO 9001:2015 certified quality management system, each custom size tee fitting undergoes a dual-stage pickling and passivation surface treatment process.

The pickling stage uses nitric-hydrofluoric acid solution to remove weld scale, heat tint, and surface contaminants from manufacturing, while the subsequent passivation treatment forms a protective chromium oxide passive layer for maximum corrosion resistance. Our custom size capability spans non-standard diameters, special wall thickness requirements, unique reducing combinations, and customer-specified dimensional tolerances.

Each pickled passivated stainless steel butt weld pipe tee is fully traceable with heat number identification, surface treatment certification, and material test reports.

Key Advantages & Application Fields
  • True Custom Manufacturing: Our custom size pickled passivated stainless steel butt weld pipe tee can be produced to your exact dimensional requirements, including non-standard ODs, special wall thicknesses, and unique reducing configurations not available from standard catalog items.
  • Professional Surface Finishing: The dual-stage pickling and passivation treatment removes all manufacturing-related surface contamination and weld discoloration, leaving a clean, uniform, and fully passive stainless steel surface optimized for corrosion resistance.
  • Aerospace & Defense: Custom-sized, pickled and passivated tees with full traceability meet stringent surface cleanliness requirements for aerospace fluid systems and defense applications.
  • Semiconductor & High-Purity Systems: Pickled and passivated surface finish meets BA (Bright Annealed) equivalent cleanliness levels for ultra-high-purity gas and chemical delivery systems in semiconductor fabrication.
  • Pharmaceutical & Biotechnology: ISO 9001 certified manufacturing with full material and process traceability supports validation requirements for pharmaceutical process piping under cGMP guidelines.
  • Specialized Industrial Projects: Custom sizes and surface treatment serve one-off engineering projects, prototype development, and specialized industrial installations requiring non-standard fitting dimensions.
Frequently Asked Questions
Q: What is the difference between pickling and passivation for stainless steel tee fittings?

A: For our custom size pickled passivated stainless steel butt weld pipe tee, pickling and passivation are complementary but distinct processes. Pickling uses an acid solution (typically nitric acid + hydrofluoric acid) to remove the thin chromium-depleted layer, weld scale, heat tint, and embedded iron contamination from the surface of the stainless steel fitting. This exposes the fully alloyed base metal beneath.

Passivation follows pickling, using nitric acid or citric acid to oxidize the surface chromium into a dense, protective chromium oxide (Cr2O3) passive film. Together, they ensure the custom size stainless steel tee fitting achieves optimal corrosion resistance with a clean, uniform surface appearance. We certify both processes per ASTM A380 and ASTM A967 standards.

Q: How do I specify custom sizes for stainless steel butt weld tee fittings?

A: When ordering our custom size pickled passivated stainless steel butt weld pipe tee, you can specify non-standard dimensions including: outside diameter (OD) for each end, wall thickness for main run and branch, center-to-end dimensions (C and M values), and end preparation type.

Simply provide your dimensional drawings or specification sheet, and our engineering team will review manufacturability and provide a quotation. Custom sizes outside the standard ASME B16.9 range are common in equipment manufacturing, retrofit projects, and specialized industrial systems. Minimum order quantities for truly custom dimensions may apply, and lead times are typically 15-30 working days depending on complexity and material availability.

Q: Is the pickled passivated surface treatment permanent, and what maintenance is required?

A: The pickled and passivated surface on our custom size stainless steel butt weld tee is self-healing under oxygen-containing environments. The chromium oxide passive film formed during passivation will naturally regenerate if the surface is exposed to air. For most applications, no maintenance is required beyond normal cleaning.

However, in aggressive environments (high chloride, reducing acids, or oxygen-depleted conditions), periodic inspection is recommended. After field welding of pickled passivated tees into a piping system, we recommend local pickling paste treatment of the weld area followed by passivation to restore the protective surface condition at heat-affected zones, ensuring uniform corrosion resistance across the entire installation.
