Oil, Gas & Petrochemical

Industry challenges· 01

What makes this application demanding.

Corrosive process fluids

Chlorides, H2S and acidic condensates accelerate failure when grade is under-specified — SS316L covers many duties but severe sour or chloride service may need duplex or nickel alloys. Send full fluid chemistry, concentration and peak temperature before quoting.

High temperature and pressure cycling

Lube oil, fuel gas and process streams see thermal swings that affect gasket materials, weld joints and pleated media collapse limits. Share normal and surge temperature, operating pressure and whether the element sees pulsating flow.

Skid footprint and differential pressure limits

Package space on compressors, lube skids and fuel polishing units constrains cartridge length and pleated area — undersized elements blind quickly; oversized units may not fit the housing. Provide housing model, port size and allowable ΔP rise.

Project documentation and traceability

EPC and operator QA files often require MTC, dimensional reports and defined inspection scope on first article. List required documents on the RFQ so lead time and cost reflect inspection and certificate preparation.

Why choose KAIFIL· 02

Why choose KAIFIL for this application.

Alloy selection for hot corrosive duty

SS316L is standard for many lube, fuel and chemical streams — we flag when chloride, H2S or acid exposure warrants duplex, hastelloy or other upgrade grades before you standardise on the wrong metal for the life of the project.

Cartridge and strainer sizing on ΔP

Pleated metal cartridges and inline mesh elements are quoted against flow, viscosity and allowable differential pressure — not only micron rating — so skid replacements do not blind faster than the incumbent element.

One RFQ for strainers, mesh and cartridges

Pump protection strainers, inline dutch weave inserts and polish cartridges often ship on the same project PO — layer stack, flange rating and cap interface are confirmed per line item on one specification review.

Products matched to this requirement.

Process notes· 05

Process notes for ordering.

Oil, gas and petrochemical filtration spans lube oil polish, fuel gas coalescing support, process liquid guard filtration and startup straining — each with different temperature, pressure and corrosion exposure. The table below is a quotation starting point; operating limits vary by equipment and must be confirmed per project before release.

Parameter	Typical range (O&G / petrochemical)	Notes for RFQ
Fluid type	Lube oil; fuel gas condensate; amine; glycol; process water	State chloride; H2S; acid type and concentration
Temperature	Approx. −20 °C to 200 °C+ (duty-dependent)	Share normal; peak and clean-in-place temperature
Pressure / ΔP	Skid-dependent; share allowable rise	Pleated area vs sintered choice — state housing limit
Retention	1–25 μm nominal common on polish duty	Absolute vs nominal rating method on RFQ
Material	SS316L default; upgrades for sour/chloride	Do not assume 316L covers all H2S exposure
Documentation	MTC; dimensional report; selected tests	Define scope on PO to align lead time

Operating limits vary by equipment — values confirmed per project.

For conical strainers, provide flange class, line size and whether temporary commissioning or permanent duty. For cartridges, send OD, length, cap style and bypass requirements. Unit price, MOQ and lead time are confirmed after specification review.

Operating limits vary by equipment — values above are typical ranges, confirmed per project.

Representative cases· 06

Representative supply cases.

FAQ· 07

Oil, gas and petrochemical questions.

Which cartridge media suits high-temperature lube oil?

Pleated SS316L mesh or sintered media depending on micron target, cleaning policy and ΔP limit. Send oil type, temperature, viscosity and housing model on the RFQ.

Can conical strainers be supplied to ASME flange ratings?

Yes — provide flange class, nominal size, mesh or perforation opening and whether temporary or permanent service. Dimensions and mesh support confirmed on drawing review.

Do you supply SS316L for sour service exposure?

SS316L covers many duties; severe H2S or high-chloride environments may need duplex or nickel alloys — send fluid analysis and temperature before quoting.

What inspection documents are available for project orders?

MTC (EN 10204 3.1 where agreed), dimensional reports and selected functional tests when listed on the PO — scope confirmed on quote.

Can mesh inserts and cartridges ship on one project PO?

Yes — common for skids needing startup strainers, inline mesh and polish cartridges together with aligned alloy and document package.

How do I specify corrosion resistance beyond SS316L?

Send chloride ppm, H2S partial pressure, acid type, concentration and peak temperature — we recommend grade and document limitations before batch release.
