    Corrosion Resistant SS Stub Ends

    Corrosion Resistant SS Stub Ends
    Product Overview

    The Corrosion Resistant SS Stub Ends are specially processed stainless steel lap joint fittings engineered for chemical processing and other aggressive media applications. Manufactured to ASME B16.9 and MSS SP-43 standards, these SS stub ends combine dimensional accuracy with long-term durability through passivated stainless steel surfaces.

    Every corrosion resistant stub end is produced from verified stainless steel plates and pipes with full material traceability. After forming and machining, each fitting undergoes pickling and passivation treatment to remove surface contaminants and restore the protective chromium oxide layer. This process significantly enhances anti-rust performance, extending service life even in humid, acidic, or chloride-containing environments.

    Quality Assurance

    Corrosion resistance starts with material quality. We source stainless steel from certified steel mills and verify the chemical composition of every heat before production. Our passivation process follows ASTM A967 standards, and we can provide salt spray test reports to demonstrate anti-rust performance.

    The production line is managed under an ISO 9001:2015 quality system, with dimensional inspection, surface inspection, and pressure verification performed at multiple checkpoints. With 15 years of experience supplying corrosion resistant pipe fittings to chemical and marine projects worldwide, we ensure material integrity and reliable performance.

    Frequently Asked Questions
    Which grade is best for seawater service?
    For seawater and chloride-rich environments, we recommend SS316L corrosion resistant stub ends. The addition of molybdenum in SS316L provides significantly better pitting and crevice corrosion resistance than SS304.
    How is the passivation treatment performed?
    The fittings are first pickled in a nitric acid solution to remove scale and surface contamination, then passivated to promote the formation of a uniform chromium oxide layer. The treated surface is tested to confirm corrosion resistance.
    Can you supply stub ends for high temperature acid service?
    Yes, but the grade selection depends on the acid type, concentration and temperature. Please provide your service conditions and our engineers will recommend the most suitable stainless steel grade for your application.
    Do you offer salt spray test reports?
    Yes. Salt spray testing per ASTM B117 can be arranged for each batch, and the test report will be included in the shipping documentation. Third-party testing is also available.
