Directly engineered in-house to comply with EN 13445, TEMA Class R/B/C, and ASME Section VIII directives for high-stakes Swiss deployments.
Founded in 1992 in Shanxi—China’s world-renowned forging capital—Shanxi Yuxin Casting & Forging Co., Ltd. (YUXIN) operates an integrated 10,000-ton annual capacity manufacturing facility dedicated to heavy industrial forging, precision heat exchanger tube sheets, and flange systems.
For Swiss engineering groups, original equipment manufacturers (OEMs), and EPC contractors operating across Basel, Zurich, Zug, and Lausanne, YUXIN serves as an authoritative Tier-1 supply partner. We bridge the gap between heavy forge capability and ultra-precise Swiss dimensional expectations (tolerances within ±0.02 mm, micro-finish Ra < 0.4 µm).
Every tube sheet produced is fully backed by EN 10204 3.1 / 3.2 certifications, meeting strict European Pressure Equipment Directive (PED 2014/68/EU), AD 2000-Merkblatt W0, and TEMA (Tubular Exchanger Manufacturers Association) Class R, B, and C standards.
Switzerland holds a unique global position in advanced manufacturing, high-value pharmaceuticals, micro-precision engineering, and clean hydro-electric infrastructure. Supply requirements differ drastically from standard global markets.
Swiss bio-pharma giants require tube sheets manufactured from super-austenitic stainless steel (316L, 904L, Hastelloy C276, Titanium Grade 2). Clean-in-Place (CIP) and Sterilize-in-Place (SIP) systems demand zero-contamination risk, polished surfaces (Ra ≤ 0.38 µm), and electropolished tube-hole grooves to prevent bacterial buildup.
Hydropower accounts for over 60% of Switzerland's domestic electricity generation. Massive turbine oil coolers, high-pressure transformer heat exchangers, and pumped-storage thermal management units rely on heavy-section forged carbon steel (A105, A350 LF2) and duplex stainless steel (2205/2507) tube sheets resistant to cyclic fatigue and vibration.
With Switzerland’s stringent Energy Strategy 2050, municipal district heating networks utilizing industrial heat pumps demand high-efficiency shell-and-tube exchangers. Precision-drilled tube sheets ensure optimal fluid dynamics, minimal pressure drop, and 30+ years of operational durability under sub-zero Alpine conditions.
Achieving absolute alignment across thousands of tube holes requires state-of-the-art CNC deep-hole drilling technology, multi-spindle gantry milling, and rigorous non-destructive examination (NDE).
YUXIN utilizes heavy multi-axis CNC drilling rigs capable of machining tube sheets up to 3,000 mm in diameter and thickness up to 800 mm. Drilled holes maintain ligamental width consistency within ±0.02 mm tolerance, eliminating tube wall compression during strength expansion.
To withstand extreme pressure differentials, tube holes are machined with single, double, or triple internal annular retention grooves. Machined according to TEMA and DIN 28182 standards, these grooves guarantee leak-tight mechanical expansion joints.
For cost-effective corrosion resistance in aggressive media, YUXIN supplies clad tube sheets combining high-strength carbon/alloy steel bases with thin layers of Titanium, Nickel Alloys (Inconel 625), or Monel 400. Ultrasonic testing (UT) guarantees 100% shear bond strength compliance.

The global heat exchanger market is rapidly shifting toward micro-channel layouts, ultra-high thermal efficiency designs, and digital twin manufacturing verification.
With Switzerland accelerating its transition toward clean energy storage, high-pressure hydrogen electrolysis systems require specialized tube sheets capable of operating at elevated pressures without hydrogen embrittlement. YUXIN’s vacuum-degassed low-alloy steels provide superior resistance to gas penetration.
Modern Swiss EPC projects require complete digital traceability. Every YUXIN tube sheet undergoes full coordinate measuring machine (CMM) scanning. Inspection laser maps are delivered digitally alongside physical shipments, allowing instant integration into 3D plant CAD models.
To optimize raw material costs without compromising corrosion protection, advanced explosion-bonded and automated laser-cladded tube sheets are replacing solid high-alloy forgings in geothermal and chemical recovery heat exchangers across Central Europe.
Addressing core technical questions regarding standard compliance, logistical routes to Switzerland, material certifications, and custom manufacturing capability.
Shanxi Yuxin Casting & Forging Co., Ltd. brings 33+ years of direct forging experience, complete single-site manufacturing (from raw billet heating to multi-axis CNC drilling), and ISO 9001 / PED 2014/68/EU certification. We offer direct factory pricing, zero agency markup, ultra-precise machining matching Swiss engineering standards, and complete EN 10204 3.1/3.2 material traceability.
We manufacture tube sheets and matching baffle plates fully compliant with TEMA (Class R, B, and C), EN 13445, AD 2000-Merkblatt W0/HP0, ASME Section VIII Division 1 & 2, and DIN 28182 specifications. Custom drawing-based manufacturing (DWG, STEP, PDF) is fully supported.
Export orders for Swiss clients are securely packed in ocean-worthy, fumigation-free plywood crates with anti-corrosion VCI wrapping. Typical transit times from Shanghai/Tianjin port to major European gateways (Rotterdam, Antwerp, Hamburg) range from 28 to 35 days, followed by inland rail or truck transport directly to Swiss industrial hubs (Basel, Zurich, Geneva, Bern).
Yes. We offer explosion-bonded clad tube sheets and weld overlay cladded units featuring Carbon Steel (A105/A350 LF2) bases bonded with Titanium (Gr. 1/2), Nickel Alloys (Inconel 625, Hastelloy C276), or Stainless Steels (316L, Duplex 2205). 100% Ultrasonic Bond Testing is performed in accordance with ASTM A578.
