1. Introduction

Stainless Steel 304/316 Pipe Caps are corrosion-resistant end fittings used to seal piping systems in demanding industrial applications. Manufactured to ASME B16.9/ANSI B16.11 standards, these caps provide leak-proof protection for pipelines carrying liquids, gases, or steam.

 

2. Key Features

 Material Grades:

• 304 Stainless Steel: Basic corrosion resistance (18% Cr, 8% Ni)

• 316 Stainless Steel: Enhanced with 2-3% Mo for acid/chloride resistance

 Manufacturing Standards:

• Complies with ASME B16.9 (welded) / B16.11 (threaded)

• Pressure ratings: Sch10S to Sch160 (150# to 2500# class available)

 Durability:

• Temperature range: -200°C to 800°C (varies by grade)

• Resists pitting, crevice corrosion, and oxidation

 Surface Finish:

• Polished (Ra ≤0.8μm for sanitary applications)

• Beveled ends for smooth welding

 

3. Advantages Over Alternatives

 Longevity: Outlasts carbon steel caps in humid/chemical environments.
 Hygienic: 316L variant is FDA-compliant for food/pharma use.
 Versatility: Suitable for high-pressure (oil/gas) and sanitary (biotech) systems.
 Low Maintenance: No coating or galvanization needed.

 

4. Typical Applications

 Oil & Gas:

• Sealing pipeline ends in refineries/offshore rigs

• Wellhead protection caps

 Chemical Processing:

• Acid/alkali transport systems

• Reactor vessel piping

 Food/Beverage & Pharma:

• CIP (clean-in-place) piping networks

• Biopharmaceutical fluid transfer lines

 Marine & Architecture:

• Boat fuel/water lines

• Decorative structural piping

 

5. Why Choose SS 304/316 Pipe Caps?

• Global Certifications: PED 2014/68/EU, NACE MR0175 for sour service

• Custom Options:

  • Threaded/socket weld connections

  • Special coatings (electropolishing, passivation)

• Inventory Ready: Standard sizes ½" to 48" (DN15-DN1200)

Technical Note: 316L (low carbon) is preferred for welded systems to prevent carbide precipitation.
