Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998. Our Oil and Gas Pipeline Strainer Cap in Stainless Steel 316 with 2" NPT and 40 Micron filtration is engineered for high-pressure applications. This strainer cap is designed to protect your pipeline equipment by removing solid particles from fluids, ensuring smooth operation and extended service life. With our decades of expertise in wire mesh and filtration products, we deliver reliability that meets the rigorous demands of the oil and gas industry.
Crafted from premium Stainless Steel 316, this strainer cap offers superior corrosion resistance, making it ideal for harsh environments, including offshore and chemical processing. The 2" NPT male thread provides a secure, leak-proof connection, while the 40 micron stainless steel mesh element effectively captures fine particles without excessive pressure drop. Each unit is machined to tight tolerances and pressure-tested to ensure performance under high-pressure conditions.
Key Features
- Material: Stainless Steel 316 – excellent resistance to chlorides, acids, and high temperatures.
- Connection: 2" NPT (National Pipe Thread) – standard taper thread for easy installation.
- Filtration: 40 micron (0.04 mm) – suitable for removing sand, rust, scale, and other particulates.
- Pressure Rating: Designed for high-pressure systems (up to 6000 psi, customizable upon request).
- Temperature Range: -20°C to +400°C (depending on sealing material, optional).
- Surface Finish: Smooth, passivated surface for reduced fouling and easy cleaning.
- Custom Options: Available with different micron ratings (20–1000 micron), alternative thread sizes, and elastomer seals (NBR, Viton, PTFE).

Our strainer cap is manufactured using precision casting and CNC machining, ensuring consistent quality and dimensional accuracy. The 316 stainless steel body withstands corrosive fluids and high-pressure environments, reducing maintenance frequency and downtime. The 40-micron mesh element is replaceable, offering cost-effective filtration over the long term.
Compared to plastic or carbon steel alternatives, our SS316 strainer cap provides superior strength and longevity, especially in sour service or offshore applications. The NPT thread design conforms to international standards, making it interchangeable with existing piping systems. Optional customizations include different thread types (BSP, BSPT), larger/smaller micron ratings, and special coatings for enhanced corrosion resistance.

Frequently Asked Questions
Q1: What is the maximum working pressure of this strainer cap?
A: The standard design is suitable for high-pressure applications up to 3000 psi. For higher pressures (up to 6000 psi), please contact us with your specific requirements – we can customize the wall thickness and thread reinforcement.
Q2: Can I use this strainer cap for natural gas pipelines?
A: Yes, the 316 stainless steel material is compatible with natural gas, and the 40 micron element can remove condensates and solid particles. However, for gas applications, we recommend selecting a suitable seal material (e.g., Viton or PTFE) to avoid swelling.
Q3: Is the 40 micron mesh replaceable?
A: Yes, the strainer cap is designed with a removable cap and a replaceable mesh element. You can order replacement 40 micron mesh baskets separately. We also offer other micron sizes (20, 50, 100, 200, etc.) upon request.
Q4: What is the difference between NPT and BSP threads?
A: NPT (National Pipe Thread) is a tapered thread standard widely used in North America. BSP (British Standard Pipe) is parallel or tapered used in Europe/Asia. Our strainer cap is available with NPT as standard, but we can produce BSP or BSPT versions if needed. Please specify when ordering.
Q5: Do you provide certificates of material (MTC) or pressure test reports?
A: Yes, we can provide Material Test Certificates (MTC) for 316 stainless steel, as well as hydrostatic pressure test reports upon request. These are available for an additional fee. Please contact our sales team for details.
Q6: What is the typical lead time for this product?
A: For standard 2" NPT 40 micron strainer caps, we usually ship within 15-20 working days after order confirmation. For custom orders, lead time may vary from 25 to 35 days, depending on quantity and specifications.
Q7: Can this strainer cap be used in seawater or brine environments?
A: Yes, 316 stainless steel offers excellent resistance to chloride-induced corrosion, making it suitable for seawater, brackish water, and brine. However, for long-term immersion, we recommend a higher grade (e.g., 316L or duplex) – please consult our engineers.
Q8: Do you offer a warranty?
A: We provide a 12-month warranty against manufacturing defects. Our after-sales team is available to assist with any installation or performance issues. We stand behind the quality of our products.
