从India供应商批量进口A182 F22 Alloy Steel Ball Valve

The A182 F22 alloy steel ball valve from SQK Valves Fittings & Automation Private Limited is a full-bore, forged alloy steel valve designed for high-pressure, high-temperature service in hydrocarbon and steam systems. The A182 F22 grade is a 2.25% chromium, 1% molybdenum ferritic alloy steel, providing creep resistance to approximately 540 degrees Celsius and tensile strength of 515-690 MPa in the normalised and tempered condition. The full-bore design maintains identical internal diameter to the connecting pipeline, minimising pressure drop and turbulence for pigging operations. The valve body is forged rather than cast, eliminating casting porosity risks and yielding superior grain structure for pressure containment.

Construction features include floating or trunnion-mounted ball designs depending on size and pressure class, with seat materials typically PTFE, RPTFE, or metal-to-metal for high-temperature service. Stem sealing uses live-loaded or gland-packed arrangements with graphite for fire-safe compliance. End connections are offered in raised-face or ring-type joint flanges per ASME B16.5, butt-weld per ASME B16.25, or socket-weld configurations. The F22 material offers markedly better oxidation resistance and elevated-temperature strength than carbon steel grades such as WCB or WCC, though below the 9Cr-1Mo (F91) or austenitic stainless ranges.

Primary applications span oil and gas production, refinery process units, power generation steam circuits, and petrochemical plants where thermal cycling and pressure spikes occur. The valve suits steam, hydrocarbon liquids and gases, and selected corrosive media within the limits of F22's chromium content. Buyers should confirm with SQK Valves Fittings & Automation Private Limited the available pressure classes (typically Class 150 to Class 2500), dimensional ranges, seat and seal material options, and applicable testing standards such as API 598 or API 6D. The supplier indicates customisable configurations, so engineering specifications should be transmitted for quotation.

SQK Valves Fittings & Automation Private Limited is an India-based supplier of industrial valves and automation equipment, currently classified under an imported tier with harbour trust status. The company has a 0.00% response rate with no logged average response time, indicating that direct communication may be unreliable or that the profile is not actively managed. No verified factory location, manufacturing certifications, workforce data, or financial details are available in the source material.

The supplier markets alloy steel ball valves for oil and gas, power generation, and marine sectors, with emphasis on customisable sizes and configurations. The available profile does not distinguish whether SQK manufactures these valves in-house or sources them through trading arrangements. Buyers should conduct due diligence on the company's production capabilities, quality system certification (ISO 9001展望, API Q1, or equivalent), and request references from comparable installations before committing to volume orders.
