From mill-certified raw stock and seamless fittings to high-strength titanium hardware, Jovzi Titanium provides fully traceable solutions engineered for demanding process environments.
In modern process engineering, flanged connections represent both an essential maintenance point and a potential failure risk. For chemical processors, biotechnology facilities, and agricultural refineries operating in Chiang Mai and the wider Upper Northern Thailand region, the management of aggressive aqueous chlorides, high-temperature organic acids, and variable pH wash streams necessitates an uncompromising approach to piping metallurgy.
Titanium stub ends (manufactured to ASTM B363 and dimensioned to ASME B16.9 or MSS SP-43) provide an optimal balance between process metallurgy and structural capital economy. Used in tandem with loose lap-joint backing flanges (carbon steel, 304, or 316L), the titanium stub end forms the only wetted surface within the flanged junction. This configuration isolates aggressive media within the inert passivated titanium circuit while completely eliminating the excessive cost of solid titanium loose backing rings.
The spontaneously formed, dense rutile/anatase titanium oxide (TiO₂) protective film heals instantly in oxygenated and wet environments, providing unmatched resistance to localized pitting and crevice corrosion.
Lap-joint configurations allow the loose backing flange to rotate freely 360 degrees around the stub end barrel, speeding bolt-hole orientation and eliminating rotational stress in complex piping arrangements.
By confining premium Grade 2 or Grade 7 titanium solely to the flared contact stub and utilizing hot-dip galvanized or epoxy-coated carbon steel backing rings, overall joint capital costs drop by up to 60%.
Historically recognized for cultural tourism, the Upper Northern Economic Corridor (encompassing Chiang Mai, Lamphun, Lampang, and Chiang Rai) has rapidly transformed under Thailand’s Bio-Circular-Green (BCG) Economy Model. The region hosts specialized advanced agro-industrial facilities, herbal and botanical extraction laboratories, high-tech sanitary processing plants, and zero-discharge industrial wastewater installations. Each sector imposes severe challenges on standard austenitic stainless steels:
Chiang Mai’s expanding nutraceutical facilities utilize supercritical fluids, warm ethanol extractions, and natural organic acids (citric, oxalic, tartaric) to process medicinal plants. Stainless steel 316L suffers ion leaching that contaminates purity runs; Grade 2 titanium stub ends ensure zero metallic pick-up, maintaining ultra-pure pharmacopeia grade outputs.
High-density electronic manufacturing, metal plating, and chemical finishing lines situated in nearby Lamphun require piping systems that endure hot acidic vapors and rinse washdowns containing metal salts. Jovzi’s Grade 7 (Ti-0.15Pd) stub ends deliver critical protection against reducing acid attack where conventional alloys fail prematurely.
With stringent environmental restrictions preserving the Ping River watershed, northern industrial parks deploy complex multi-effect distillation (MED) and mechanical vapor recompression (MVR) systems. Titanium stub ends and elbows eliminate chloride stress corrosion cracking (SCC) under boiling, high-salinity brine conditions.
All titanium stub ends supplied by Jovzi Titanium to Chiang Mai process contractors are manufactured under rigorous QA regimes according to international standards. Seamless types are formed from ASTM B338/B861 raw stock through precision hot-die flaring and CNC face profiling, while welded configurations conform to ASTM B363/ASME B16.9 with 100% radiographic or liquid penetrant inspection.

* Custom wall thicknesses, modified stub lengths (e.g., custom weld-neck clearance for automated orbital welding), and bespoke cladding rings can be machined directly against client CAD prints (.dwg / .step).
Procurement engineers across Southeast Asia frequently grapple with the initial price delta between Grade 2 titanium and conventional 316L or 2205 Duplex stainless steel. However, an analysis of the Total Cost of Ownership (TCO) across a 15-year lifecycle in high-chloride, acidic, or high-purity environments demonstrates decisive financial returns favoring titanium.
Unlike carbon steel or low-alloy stainless steels where engineering design requires 2.0 mm to 4.0 mm excess wall thickness to account for wall thinning, titanium systems are designed with zero corrosion allowance. This yields thinner wall requirements (Sch 10S vs Sch 40S) and dramatic structural weight reductions.
In continuous agricultural refining and pharmaceutical extraction facilities in Chiang Mai, an unscheduled gasket blowout or stress-corrosion leak causes production shutdowns costing tens of thousands of dollars per day. Titanium stub ends provide permanent metallurgical peace of mind.
Thailand’s national policy heavily incentivizes industrial technologies with extended operational lifespans and low environmental disposal footprints. Titanium’s 100% recyclability and 40+ year lifecycle completely satisfy ESG and BCG regulatory frameworks.
