The ANSI Standard Cast Iron Strainer is a cost-effective and durable filtration solution tailored for industrial pipeline systems, designed to trap impurities (such as debris, particles, and sediments) and protect downstream equipment like pumps, valves, and meters from clogging or damage. With its rugged cast iron/ductile iron body and high-performance SS304 strainer element, this strainer excels in low to medium-pressure applications—making it a go-to choice for water treatment, HVAC, chemical processing, and general industrial fluid handling. Compliant with strict ANSI and API standards, it ensures seamless compatibility with global pipeline setups, while its wide size range (1/2”~24”) and dual pressure ratings (125LB/150LB) adapt to diverse flow rate and system pressure needs, delivering consistent filtration performance and extending the lifespan of your industrial equipment.
Key Features & Customer Benefits
Durable & Cost-Effective Construction: Body options of cast iron (high rigidity) and ductile iron (enhanced impact resistance) balance durability and affordability, suitable for budget-conscious projects without compromising performance.
Superior Filtration Element: Equipped with SS304 stainless steel strainer element—resistant to rust and corrosion, easy to clean/replace, and capable of filtering fine particles to maintain fluid purity.
Global Standard Compliance: Follows ANSI (design), ANSI B16.10 (face-to-face dimensions), ANSI B16.1 (flange), and API 598 (testing) standards, ensuring hassle-free installation with existing ANSI-compatible pipelines and meeting international quality requirements.
Versatile Application Range: Ideal for handling water, oil, mild chemicals, and other non-aggressive fluids in industries like HVAC, municipal water treatment, food processing (non-direct contact), and light manufacturing.
Low Maintenance: Simple structure with cast iron bonnet (secure sealing, easy to open) reduces disassembly time during element cleaning/replacement, minimizing system downtime and maintenance costs.

FAQ
1. What’s the difference between cast iron and ductile iron bodies, and how do I choose?
Cast iron is cost lower and has good rigidity, suitable for static, low-vibration environments (e.g., fixed water pipelines). Ductile iron has higher tensile strength and impact resistance, ideal for applications with mild vibration or temperature fluctuations (e.g., HVAC systems). Choose based on your environment’s vibration and load conditions.
Can this strainer handle corrosive fluids like acids or alkalis?
No. The cast iron/ductile iron body is prone to corrosion in acidic/alkaline fluids. This strainer is designed for non-corrosive fluids (e.g., water, mineral oil, mild detergents). For corrosive applications, we recommend stainless steel strainers—contact our team for alternatives.
3. How often should I clean or replace the SS304 strainer element?
Cleaning frequency depends on fluid impurity levels: for clean fluids (e.g., treated water), clean every 3~6 months; for fluids with high sediment (e.g., raw water), clean monthly. Replace the element only if it’s cracked, deformed, or has excessive wear (typically every 2~3 years with regular cleaning).
4. Is this strainer compatible with ANSI B16.1 flanges of all sizes?
Yes. It follows the ANSI B16.1 flange standard, so each strainer size (1/2”~24”) matches the corresponding size of ANSI B16.1 flanges. Ensure the flange size aligns with the strainer size for a secure, leak-free connection.
5. What does API 598 testing include, and why is it necessary?
API 598 testing includes hydrostatic pressure tests (to check for body/bonnet leaks) and pneumatic tests (to verify sealing performance), plus visual inspections of dimensions and surface quality. It ensures the strainer meets leak-tight and structural safety requirements, avoiding fluid leakage and equipment damage in operation.
6. Can I use this strainer for high-temperature fluids?
It’s suitable for fluids up to 204°C (400°F)—cast iron/ductile iron maintains stability within this range. For fluids above 204°C, we recommend high-temperature resistant strainers (e.g., cast steel models) to prevent material deformation.
7. Does the strainer come with a warranty?
Yes, we provide a 12-month warranty from the date of delivery. The warranty covers defects in materials and manufacturing (e.g., body cracks, defective gaskets) but does not include damage from improper installation, misuse, or corrosion from incompatible fluids.
8. Do you offer custom mesh sizes for the SS304 strainer element?
Our standard SS304 element uses 40-mesh (suitable for most industrial impurity filtration). For custom mesh sizes (e.g., 20-mesh for large particles, 100-mesh for fine filtration), we offer customization for bulk orders (minimum 50 units). Contact our sales team to specify your mesh requirement.
