ASME B16.11 ASTM A234 WP91 Cap
Overview
ASME B16.11 ASTM A234 WP91 pipe cap (also known as plug or cap) is a pipeline terminal sealing fitting designed specifically for high-pressure, high-temperature, and corrosive industrial environments. It is made of high-quality WP91 chromium molybdenum alloy steel and forged into one piece, strictly following the ASME B16.11 forged pipe fitting standard and ASTM A234 alloy steel pipe fitting specification. It has excellent mechanical strength, extreme temperature adaptability, and corrosion resistance. It is the core sealing fitting for pipeline systems in key fields such as petrochemicals, power generation, nuclear power, and offshore oil and gas extraction, ensuring safe sealing and long-term stable operation of the system.

Application Highlights
ASME B16.11 ASTM A234 WP91 pipe caps are widely used in the following key industries due to their high pressure, high temperature, and corrosion resistance characteristics:
Petrochemical/Refining
Sealing of crude oil transportation pipelines, reactor outlets, and chemical medium pipeline terminals.
Electric power generation
Steam pipelines for thermal/nuclear power boilers, cooling systems for steam turbines, waste heat recovery devices.
Offshore oil and gas
Pipeline extraction on offshore platforms, pipeline sealing in corrosive marine environments.
Metallurgy/Steel
High temperature flue gas pipelines, smelting medium transmission systems.
Pharmaceutical/Semiconductor
Aseptic sealing of high-purity medium transmission pipelines.
Other
Special pipeline systems such as aerospace, military, and nuclear power that require extremely high safety and reliability.
Core strengths
01
Extreme temperature tolerance
It maintains good toughness even in low temperature environments (-20 ℃), adapts to alternating high and low temperature working conditions, and has no risk of deformation or failure in high-temperature steam and heat medium transmission.
02
High pressure bearing capacity
With high tensile strength and excellent creep strength, it can be adapted to perfectly meet the sealing requirements of high stress pipeline systems and eliminate leakage hazards.
03
Super strong corrosion/oxidation resistance
Contains chromium (Cr) and molybdenum (Mo) core alloy components, effectively resisting corrosion and oxidation from acidic and alkaline media, crude oil, and high-temperature flue gas, extending pipeline service life, and reducing maintenance costs.
04
Welding compatibility
The forging process ensures that the material is uniform and dense, without any weld defects, and forms a firm sealing surface after welding with pipes of the same material, which is suitable for on-site welding construction needs.
