KEPUNI pushes global orbital welding expansion with patents, service network and high-yield claims

Shanghai-based KEPUNI is expanding in orbital welding as demand rises for high-purity pipe joining in pharma, semiconductor, food and energy markets. The company says its patented equipment, global service footprint and 99%+ first-pass weld acceptance rate are helping win customers and approvals across regulated industries.

Why it matters: - KEPUNI is targeting industries that depend on clean, repeatable welds, including pharmaceuticals, semiconductors, food and beverage, oil and gas. - The company’s pitch centers on verified quality, which matters in regulated manufacturing where contamination and rework can delay production. - KEPUNI says its equipment helps customers improve qualification rates and reduce reliance on manual welding.

What happened: - Shanghai-based KEPUNI said it is strengthening its position in automated tube welding through 26 authorized patents, a broad product lineup and service coverage across Germany, Japan, the United States, India and Brazil. - The company was founded in 2014 and says it has 280 employees, including 36 R&D engineers and technicians. - KEPUNI reports annual production capacity of 3,000 units and a 10,000 m² production park in Shanghai. - The company counts BYD and PetroChina Pipeline Bureau among its designated customers.

The details: - KEPUNI’s product range includes closed orbital weld heads, open pipeline weld heads, tube-to-tube-sheet welders, orbital cutters, cold welding machines and ultrasonic metal-welding machines. - The company says its patent portfolio covers technologies in closed tube-to-tube weld heads and tube-to-plate weld head positioning devices. - Its intelligent power supply control systems use a 10-inch high-definition touchscreen and a built-in welding database that matches procedures based on inputs such as tube material and wall thickness. - The equipment uses real-time closed-loop feedback with automatic arc length control and weld seam tracking. - KEPUNI says its modular K-76, K-170 and K-325 weld head series cover tube diameters from 3.175 mm capillary tubes to 325 mm and above. - The dual cooling system combines circulating water cooling to support longer duty cycles and multi-pass welding. - The XD-20PRO power supply for closed orbital weld heads features a 12-inch color touchscreen, Siemens PLC control, dual cooling and storage for up to 600 welding programs. - The XD-20PRO is compatible with weld heads covering pipe diameters from 3.175 mm to 168 mm and wall thicknesses from 0.5 mm to 3 mm. - The K Series and XD-K Series open weld heads handle outer diameters from 19 mm to 325 mm and wall thicknesses up to 13 mm for oil and gas, petrochemical and power generation uses. - The TB-35 and TB-65 tube-to-tube-sheet welders serve heat exchanger, boiler and condenser manufacturing. - KEPUNI also lists U-tube weld heads, split-type weld heads, girth welding systems, orbital cutting machines, tube facing machines, hand-held laser welding machines, cold welding machines and ultrasonic metal-welding machines in its broader ecosystem. - The company says its systems maintain a first-pass weld acceptance rate above 99%, weld accuracy of ±0.05 mm and a non-destructive testing pass rate above 99%. - KEPUNI says the systems comply with FDA, GMP and ASME standards. - The welding process uses TIG, or GTAW, technology and is compatible with stainless steel, carbon steel, alloy steel, titanium alloy, nickel-based alloys and copper alloys. - KEPUNI says closed weld head designs help reduce particle generation for semiconductor applications and support leak-proof joints for pharmaceutical water and CIP/SIP systems.

Between the lines: - The company is positioning itself at the intersection of two strong demand pools: high-purity clean piping and heavy-duty industrial piping. - That dual focus helps KEPUNI address both the fastest-growing semiconductor and pharmaceutical applications and the larger oil and gas market. - KEPUNI’s claims of high yield, documented quality and multi-country support are aimed at winning specification approvals in regulated buying environments. - Third-party market data cited in the release shows the orbital welding market was worth about $1.32 billion in 2024 and could reach $2.07 billion by 2030. - The release also says oil and gas was the largest application segment in 2024, while semiconductor and pharmaceutical high-purity piping were the fastest-growing segments. - KEPUNI says it has a customer satisfaction rate above 95% and a core customer repurchase rate above 88%. - The company says it has provided on-site repair support in Turkey and ranked among the top three domestic equipment manufacturers in China for three straight years in sanitary piping and industrial circumferential welding.

What’s next: - KEPUNI is using exhibitions and overseas service coverage to broaden awareness among international buyers. - In July 2026, the company showcased LNG, chemical processing and power generation welding systems at the BEW exhibition in Shenzhen. - The company says its strategy is to keep expanding its verified quality footprint through patent-protected technology, a wider product matrix and stronger global service coverage. - Future competitive gains will depend on continued customer audits, third-party testing and service scale in key markets.

The bottom line: - KEPUNI is trying to turn technical verification, patents and global service into a moat in a market where documented weld quality increasingly drives purchase decisions.
