The Sight Glass is designed, manufactured, and tested in accordance with ASME B16.34 / BS 3463 / Manufacturer Standard. Compliance documentation and Material Test Certificates (EN 10204 3.1) are provided with every order.
Standard construction is carbon steel, stainless steel (CF8 / CF8M), and special alloy grades. Alternative and upgraded grades -- Duplex, Super Duplex, Inconel, Monel, Hastelloy, and NACE MR0175 trims for sour service -- are available on request.
It is offered in DN15 (1/2") to DN300 (12") with Class 150# / Class 300# / PN16 / PN40. End connections include flanged (RF / RTJ), butt-weld, socket-weld, and screwed ends as per specification.
Yes. Supreme Valves India is an established exporter of industrial valves to Saudi Arabia (KSA), the UAE, Qatar, Kuwait, Oman, Bahrain, and across the Gulf. We provide sea-worthy export packing, EN 10204 3.1 / 3.2 certification, certificate of origin, and support for SABER / SASO conformity on KSA shipments.
Every valve undergoes hydrostatic shell and seat testing per API 598 / ISO 5208. Documentation includes EN 10204 3.1 MTC (3.2 on request), NDT reports, and fire-safe (API 607) or NACE MR0175 certification where applicable. Third-party inspection by TÜV, SGS, Bureau Veritas, or Lloyd's Register can be arranged.
Order quantities are flexible -- from single units for stocked items to bulk volumes for project requirements. Lead time depends on size, material, and quantity; please contact our team with your specification for a firm delivery schedule and quotation.
