Carbon Steel Mechanical Filter Housing – Epoxy & Rubber Lined Series (Heavy Duty)
Stark Carbon Steel Mechanical Filter (STK2 Series) offers a cost-effective solution for large-scale filtration. Manufactured from heavy-duty Q235B steel (up to 10mm thick), it features optional Epoxy Coating or Rubber Lining for superior corrosion resistance in municipal and seawater applications.
Product Description
Cost-Effective Solution for Mega-Scale Filtration.
For vessel diameters exceeding 1500mm, stainless steel becomes prohibitively expensive. The Stark STK2 Carbon Steel Series provides robust structural integrity at a fraction of the cost. With models ranging from Ø500mm up to a massive Ø3200mm, it handles flow rates up to 120 T/h per unit.
Anti-Corrosion Options:
1. Epoxy Coated: Economical choice for standard fresh water applications.
2. Rubber Lined (3-5mm): Premium protection for Seawater Desalination or abrasive sand filtration. The rubber layer effectively resists chloride corrosion and the physical abrasion of moving media.
Note: Price includes the pressure vessel only. External piping, valve manifolds, and media are sold separately.
Lining Specs & Spark Testing:
Quality assurance is critical for lined vessels. To view our rubber lining thickness standards, spark test reports (for pinholes), and detailed dimensional drawings, please reference the technical data at our manufacturing division:

Applicable Industry
- Seawater Desalination (SWRO):
Rubber-lined carbon steel vessels are the industry standard for SWRO pre-treatment, offering excellent resistance to high-salinity corrosion. - Municipal Water Treatment:
Cost-effective replacement for concrete sand filter pools. A single Ø3200mm vessel can handle 120 tons/hour, ideal for city water supply upgrades. - Large Industrial Cooling:
Robust side-stream filtration for power plants and steel mills, where durability and large flow capacity are paramount.
Advantage One
Advanced Corrosion Protection (Rubber Lining)
For harsh environments, paint isn’t enough. Our Rubber Lining Option involves bonding a 3-5mm layer of natural rubber to the interior.This lining provides dual protection: it is chemically inert to chlorides (seawater) and mechanically resilient, absorbing the impact of sand particles during backwashing to prevent abrasion.Advantage TWO
Massive Scale Engineering (Up to Ø3200mm)
We specialize in heavy-duty fabrication. Our flagship MMFC-D3200 model features a 3.2-meter diameter and 10mm wall thickness.Capable of processing 120,000 liters per hour, these mega-vessels reduce the footprint of your filtration plant by minimizing the number of tanks required.Related Products
