Precision Hardfacing & Cladding for Valve Seats, Wedges, Stems & Bodies
Rooted in China's valve manufacturing heartland since 2006, HUAYAN has developed dedicated CNC welding and cladding machines for gate, globe, check, ball and control valves. Our systems deposit Stellite, nickel alloys and other hard-sealing materials onto seats, wedges, stems and bodies with stable, porosity-free metallurgical bonding — clamping range Φ10–Φ600, customizable.
Automated Welding & Cladding for Pressure Vessels, Tanks & Heat Exchangers
HUAYAN designs gantry, saddle and multi-axis welding systems for fabricating pressure vessels, storage tanks, reactors and shell-and-tube heat exchangers. From tube-to-tubesheet joints and longitudinal/circumferential shell seams to nozzle (saddle) intersections and head penetrations, our machines deliver single-side welding with back formation, full penetration and repeatable NDT-grade quality — handling carbon steel, stainless, nickel alloys and clad materials across thin- and thick-wall specifications.
Precision Welding & Cladding for Automotive, Motorcycle & Hydraulic Components
HUAYAN supplies circular-seam and cladding automation for the automotive, motorcycle and hydraulic-parts supply chain around China's "Auto & Motorcycle Parts Hometown" (Tangxia, Ruian). Our LS/WS girth welders and multi-axis CNC systems handle hydraulic cylinder bodies and rods, drive shafts, steering knuckles, pump bodies and impellers with consistent penetration and minimal distortion, while laser and hot-wire TIG cladding restore or hardface wear surfaces on shafts, buckets and teeth for longer service life.
Hardfacing & Cladding for Mining, Drilling & Oilfield Wear Parts
HUAYAN delivers hardfacing and cladding solutions built for the harsh duty of mining, drilling and oilfield service. From mining cutting bits, scraper conveyor components and hydraulic props to oilfield drill collars, rotor shafts and drill-pipe internals, our laser, hot-wire TIG and pipe-inner cladding systems deposit tungsten carbide, cobalt and nickel alloys that resist abrasion, corrosion and high temperature — extending part life far beyond the uncoated baseline.
Corrosion-Resistant Welding & Cladding for Chemical, Sanitary & Hardware Parts
HUAYAN serves the chemical, sanitary and hardware sectors with clean, corrosion-resistant joining and cladding. From chemical reactors and process piping to sanitary tubes, float balls and bellows — plus rollers, cylinders and general hardware — our girth, multi-axis and cladding systems work stainless steel, nickel alloys, copper/bronze and aluminum to deliver leak-tight, food- and corrosion-grade finishes with stable, repeatable quality.
Automated Welding for Ship Hulls, Piping & Marine Structures
HUAYAN supports shipyards and marine equipment makers with automated welding for hull structures, pipe spools and onboard systems. From flange-pipe-plate joints and T-pipes to saddle intersections, shafting and pump/impeller components, our saddle, girth and robotic welding systems handle carbon steel, low-alloy steel, stainless and aluminum alloys with the penetration, consistency and traceability demanded by marine-classification work.
