Damaged stainless steel drums do not necessarily have to be replaced. Depending on the nature of the damage, damaged drums can often be professionally repaired. Stainless steel drums are designed for a long service life. Nevertheless, damage is inevitable in industrial use. Dents caused by contact with forklifts, cracks in weld seams, worn sealing surfaces, or corrosion damage often result in containers being removed from the production process. However, not every instance of damage requires replacement. In many cases, the functionality of a stainless steel drum can be restored through professional repair. Whether a repair is possible and economically feasible depends on the condition of the vessel and the requirements for its future use. A technical condition assessment therefore forms the basis for any decision. Typical Signs of Damage in Industrial Use Transportation, cleaning, and daily handling leave their mark even on high-quality stainless steel drums. The most common types of damage include: - Dents and deformations on the shell or bottom - Damaged flanges and sealing surfaces - Cracks in welds or in the tank…

BOLZ INTEC develops stainless steel vessels for the storage, transport, and processing of pharmaceutical active ingredients (APIs), powders, granules, and... In pharmaceutical manufacturing processes, vessels must meet stringent requirements for hygiene, product safety, and cleanability. At the same time, when handling powders and bulk solids, factors such as discharge performance, product residues, and contamination risks play a crucial role. BOLZ INTEC manufactures stainless steel vessels for a wide range of applications throughout the process chain. The portfolio includes transport and storage containers, mixing and reaction vessels, fermenters, and WFI tanks for high-purity media. The containers are designed according to specific process requirements in terms of material grade, capacity, surface finish, and equipment. For use in GMP-regulated production environments, the containers are designed in accordance with hygienic design principles. The aim is to minimize dead spaces and hard-to-access areas, thereby supporting reproducible cleaning processes and safe operation. Depending on the application, FDA-compliant…

In many areas of the pharmaceutical, chemical and fine chemical industries, the demands on materials and process reliability continue to increase.... In many areas of the pharmaceutical, chemical and fine chemical industries, the demands on materials and process reliability continue to increase. Especially when handling aggressive media, high temperatures or high-purity applications, conventional stainless steels often reach their limits. For these demanding environments, BOLZ INTEC develops customized Hastelloy drums and vessels and equipment solutions. Hastelloy is one of the most high-performance nickel-based alloys used in industrial drums and vessel construction. Due to the specific combination of nickel, chromium and molybdenum, these materials offer outstanding resistance to chloride-containing media, oxidizing and reducing acids, as well as pitting, crevice and stress corrosion cracking. Even under high thermal loads, Hastelloy vessels maintain their structural stability and ensure long-term process reliability. In sensitive production environments, material selection plays a decisive role. Even…

In pharma production, internal liquid transfer is often seen as logistics, but it directly impacts process reliability, product quality, and reproducibility. In pharmaceutical production, internal liquid transfer is often still viewed as a purely logistical step. In reality, however, it has a direct impact on process reliability, product quality, and reproducibility. The CSTS (Closed Liquid TransferSystem) from Bolz Intec has been used in this context for years. It enables the closed transport of liquids between process stages such as reactors, filters, or dryers—without contact with the environment and without opening the system. During operation, several requirements are addressed simultaneously: The transfer is emission-free, the product remains in motion during transport, and both emptying and cleaning can be performed within the closed system. - Emission-free liquid transfer - Closed-loop process control without opening - Gentle mixing during transport - Complete emptying and integrated CIP cleaning - ATEX-compliant design for hazardous areas The combination of these functions reduces interfaces…

Asymmetrical drum funnels for controlled filling and emptying of drums and similar containers. Asymmetric funnels are used primarily in the chemical, pharmaceutical, and food industries and are designed for applications with high requirements for material resistance, hygiene, and process reliability. Manufactured from austenitic stainless steel 1.4404 (AISI 316L). This material offers high corrosion resistance to aggressive media as well as good mechanical properties and is suitable for contact with sensitive products. The asymmetrical design supports targeted material flow and facilitates largely complete emptying, thereby reducing product residues and losses. To improve cleanability, the inner surfaces are treated using the Optimized Grind Finishing (OGF) process. The resulting surface roughness of Ra < 0.25 µm reduces particle adhesion and supports hygienic cleaning processes. In addition, the drum funnels are electropolished to further increase surface smoothness and corrosion resistance. The design of drum funnels complies with GMP guidelines…
