Material Introduction

Stainless steel materials such as 304, 316L, and duplex stainless steel provide excellent corrosion resistance, temperature resistance, and mechanical strength. These properties make stainless steel flanges suitable for demanding industrial pipeline systems.

Production Process

Before installing the Stainless Steel Flange, it is essential to thoroughly clean the sealing surface of the flange. Use specialized tools to remove oil stains, oxide layers, dust, and any residual installation debris on the surface. Ensure that the sealing surface is smooth, flat, and free of scratches or damages, to prevent impurities from affecting the sealing effect and lay a solid foundation for stable connection.

When assembling the gasket and bolts, consider the material characteristics, usage conditions, and pressure level of the component. Select compatible and precisely sized matching products to avoid sealing failure or electrochemical corrosion due to incompatible parts. This ensures the structural stability and service life of the installation.

When tightening the bolts, follow the principle of symmetrical and uniform force application to ensure balanced force on each bolt and prevent excessive force on a single area from causing the flange to deform or pressure unevenness resulting in sealing gaps. This makes the flange connection more secure and tight, effectively preventing medium leakage.

After putting into operation, conduct regular inspections of the connection points, focusing on checking if the bolts are loose, if the gasket is aging or damaged, if there are any leakage marks on the sealing surface, and whether the stainless steel surface has rusted. Address any issues promptly to ensure the safe and stable operation of the pipeline system.

Installation and Maintenance

Logistics and Packaging

The packaging of Stainless Steel Flange adopts two mainstream methods: wooden packaging boxes or standard pallets. The packaging structure is sturdy and highly protective, which can effectively withstand the jolts and collisions during international transportation, preventing scratches and deformations on the products. It meets the strict requirements of cross-border transportation.

According to the special needs of customers, we can also provide customized packaging services. We can adjust the packaging specifications and protection methods as per requirements to meet the transportation and storage needs in different scenarios.

Each batch of products is accompanied by clear and standardized product labels, detailing key information such as product model, specification, material, and quantity. This not only facilitates the customers' receipt and verification but also fully complies with the relevant standards and requirements for international export, ensuring the smooth customs clearance and delivery of the goods.
