Customer Background

A mid-sized chemical plant in Southeast Asia produces industrial cleaning agents and chemical additives. Their production line includes a liquid transfer pipeline that moves mixed chemical solutions from a reactor to a filling station. Over time, solid particles such as undissolved raw materials and pipe welding debris accumulated in the line, causing frequent valve jams and seal wear.

The Problem

The plant was facing several operational headaches. Solid impurities in the liquid ranged from 80 to 200 mesh in size. Their existing simple mesh filter could not capture these particles effectively. Valve clogging happened almost every week. Each cleaning required about 40 minutes of downtime, which directly affected their daily output. The plant needed a reliable filtration solution that could be installed without major pipeline modifications.

The Solution

After reviewing their pipeline conditions, we recommended the JYBF25-304 stainless steel basket strainer. The key specifications matched their needs perfectly. The strainer body and basket are made of 304 stainless steel with a blasted surface finish. The housing diameter is 108 millimeters. The filtration precision is 100 mesh, ideal for capturing particles in their range. The seal uses EPDM material, which is compatible with their chemical solution. The unit comes with a 1 inch flange connection following ANSI standards, a 1/2 inch drain port, a 1/4 inch vent port, and a standard pressure gauge.

The strainer was installed on the horizontal pipe section between the reactor outlet and the filling valve. Installation was simple and required no major changes to the existing piping.

The Results

The stainless steel basket strainer has been running steadily for more than four months. The customer reported the following improvements.

First, the valve clogging problem has been completely resolved. The 100 mesh basket effectively traps almost all solid particles. The filling valve now operates smoothly without any interruption.

Second, maintenance has become much easier. The plant cleans the strainer every two weeks by opening the drain port. Each cleaning takes less than 15 minutes, saving over 60 percent of the time compared to their previous solution.

Third, the pressure gauge allows operators to monitor the strainer condition in real time. The plant has set an internal rule to clean the basket when the pressure difference reaches 0.06 MPa. This prevents unexpected blockages and keeps production running.

Fourth, the EPDM seal has performed well with no signs of swelling or leakage. The chemical compatibility is fully satisfactory.

Customer Feedback

The production manager shared their experience. He said the stainless steel basket strainer looks compact but makes a big difference on the line. Before, they had to stop the line every week to fix valves. Now, they don’t worry about clogs for an entire month. The drain port and pressure gauge are very practical. Operators can tell at a glance when cleaning is needed.

Next Steps

Based on this successful trial, the customer has already installed the same stainless steel basket strainer on two other similar liquid lines. They have also added this model to their standard equipment selection list for future plant expansions.
