API 602 Strainer

An API 602 strainer is a high-integrity, compact mechanical filtration component featuring a heavy-wall forged steel body (such as ASTM A105 or A182 F316), engineered to match the stringent design principles of small-bore forged valves. Designed primarily for high-pressure, high-temperature utility loops up to 2 inches in diameter, it contains a rugged internal stainless steel screen that intercepts solid particles to protect downstream instrumentation, steam traps, and miniature control valves. The forged construction eliminates the risk of porosity defects, providing maximum reliability under severe operational fatigue and thermal cycling. These strainers are standard specifications for high-pressure steam bypass lines, petrochemical processing systems, and hydraulic instrumentation panels. Sourcing managers and high-pressure pipeline contractors can eliminate sub-zero brittle fracture risks and protect downstream pumps by importing certified API 602 strainers directly from premier manufacturers in China via our B2B commercial platform.
