Stainless steel tanks
Custom Manufacturing, Pressure Testing & Certified Welding with our focus on precision
At Steel Spirals, we specialize in the custom production of stainless steel tanks, tailored to meet the specific operational, technical, and environmental requirements of each client. Every tank is designed with a strong focus on functionality, durability, and long service life, suitable for industrial use as well as demanding applications requiring high hygiene standards, pressure resistance, or chemical stability.
We deliver single-wall and multi-wall tanks, tanks with integrated agitators, inspection openings, flanges, pipeline connections, and other custom-built features based on your project needs. Our manufacturing process is highly flexible – whether for one-off units or serial production – always with a focus on quality and individual solutions.
Hydrostatic Pressure Testing
For tanks intended for pressure operation or heavy-duty environments, we provide hydrostatic pressure testing as part of our quality control or on request. This ensures that every tank performs under high-stress conditions without leaks or structural deformation.
Welding Procedure Qualification (WPQR)
Weld quality is a critical factor in the performance and safety of any tank. That’s why we rely exclusively on certified welding procedures in accordance with international standards (such as EN ISO 15614-1), including full Welding Procedure Qualification Records (WPQR). This guarantees that every weld is executed by trained professionals under controlled conditions, with maximum attention to strength and sealing integrity.
Craftsmanship Meets Technology
Our production capabilities combine skilled craftsmanship with modern technology—from precision material cutting to robotic welding and final inspection. We serve clients across various sectors, including water treatment, food processing, chemical production, and energy.
Whether you need a stainless steel tank for potable water, a process vessel for production, or a corrosion-resistant tank for aggressive media, we’ll deliver the right solution. Reliable. High-quality. Tailor-made.
