Hastelloy C-276 Wedge Wire Screen for Fine Chemical Processing

Product features:

The standout advantages of this wedge wire screen include its  and ultra-high screening precision. Made from Hastelloy C-276 alloy, it exhibits excellent resistance to a wide range of corrosive media, including hydrochloric acid, sulfuric acid, and chlorine gas, making it suitable for use in fine chemical plants where traditional stainless steel screens would corrode rapidly. The 0.05mm screen slot width provides a screening precision of 99.8%, ensuring accurate classification of ultra-fine catalyst particles and chemical intermediates, which is critical for maintaining product purity and process efficiency. The mortise and tenon joint system eliminates gaps between panels, preventing cross-contamination between different materials and simplifying cleaning, as there are no crevices where chemical residues can accumulate. It also holds ASME certification, guaranteeing compliance with international pressure vessel and chemical processing standards.

Product specifications:

This fine chemical wedge wire screen has a standard panel size of 1000mm (width) × 2000mm (length), with a screen surface thickness of 6mm to ensure structural stability while maintaining a lightweight design. The screen slot width is precisely manufactured to 0.05mm, enabling ultra-precise screening of particles as small as 0.05mm. The open area ratio of 22% balances screening precision and material throughput, ensuring efficient processing without compromising product purity. The screen can operate within a temperature range of -30℃ to 180℃, adapting to both low-temperature chemical storage and high-temperature reaction environments. Its mortise and tenon joint system uses precision-machined joints that require no additional fasteners, providing a seamless and leak-free connection between panels. Each panel weighs approximately 58kg, facilitating easy installation and replacement. The screen’s corrosion resistance ensures a service life of over 4000 hours in harsh chemical environments, reducing maintenance costs and operational downtime.

Product application:

This Hastelloy C-276 wedge wire screen is a versatile solution for a wide range of fine chemical and pharmaceutical applications. In catalyst manufacturing facilities, it is used to classify ultra-fine catalyst particles, ensuring consistent particle size distribution that maximizes catalytic activity and reaction efficiency. In fine chemical plants, it separates chemical intermediates from reaction mixtures, producing high-purity products that meet strict industry standards. It is also suitable for pharmaceutical drug production, where it filters active pharmaceutical ingredients (APIs) and excipients, ensuring product purity and compliance with FDA and ICH guidelines. Its corrosion resistance makes it particularly useful in processes involving strong acids, alkalis, or organic solvents, where traditional screens would fail to perform, leading to product contamination and production delays.
