PROCESS & DOCUMENTATION

Manufacturing quality, at its most fundamental, is compliance to specifications. The fundamental basis for managing operations to produce quality products is the quality of design and compliance to standards.

Poor manufacturing quality comes at a significant cost. Through inefficiencies, delays, direct expenses, and customer dissatisfaction, rework, scrap, product failures, and recalls may significantly harm a manufacturing.

Quality assurance in manufacturing contains three major functions: quality design and engineering, quality control, and quality management.

Today, INOVATERM manufactures goods on time, the first time, and every time in order to attain and maintain a competitive position in worldwide markets by sticking to its core principles.

In each project, INOVATERM provide the quality control documentation indicated below in accordance with customer specifications.

Pickling & Passivation

Pickling and Passivation are essential surface treatment processes for stainless steel fabrications to ensure long-term corrosion resistance and durability. During welding, cutting, or heat treatment, oxide layers, heat discoloration, and iron contamination can form on the stainless steel surface, significantly reducing its corrosion performance. Pickling is a chemical cleaning process that removes these unwanted layers, restoring a clean and uniform metal surface and preparing it for optimal protection.

Following pickling, the passivation process allows a protective chromium oxide layer to form naturally on the stainless steel surface. This invisible but critical layer is what gives stainless steel its corrosion-resistant properties. Passivation enhances resistance to rust, pitting, and environmental attack, especially in aggressive conditions such as marine, chemical, food, and pharmaceutical applications.

Pickling and passivation can be applied using different methods such as immersion baths, pickling gels, or spray applications, depending on component size and site conditions. These processes are particularly important after fabrication and on-site welding, ensuring that stainless steel components meet international standards and maintain their performance, appearance, and service life over time.
