Meta: How EMT Piping's cavitation jet pig cleared fused wax and hardened scale from a long-distance multi-product pipeline — without chemical batching.

A mid-sized operator in Central Asia was experiencing a 12% flow reduction on a 320 km crude oil pipeline during winter months. After inspection, heavy wax deposition was identified. The operator selected a mandrel pig with spring-loaded steel brushes and dual sealing cups, running it at a controlled speed of 2 m/s with increased differential pressure. Three consecutive pigging runs removed approximately 1.2 tons of wax and restored the line to within 3% of the original design capacity. This single intervention delayed the need for chemical treatment and extended the operating cycle by more than eight months.

At EMT, we take pride in delivering precision-engineered corrosion monitoring solutions that meet the highest industry standards. In this recent case, we successfully completed a large-volume order of corrosion probes for a long-term international client in the oil and gas sector. This shipment highlights our attention to detail, modular packaging capabilities, and commitment to quality assurance throughout the production and delivery process.

As part of our commitment to delivering high-performance pipeline monitoring solutions for the global oil and gas industry, Shenyang Emt Piping Technology Co.,ltd. is proud to announce the successful completion of a new batch of pig signal indicators, precision-engineered for use in critical petroleum and natural gas pipeline systems. These units have successfully passed factory testing and are now awaiting final packaging and international shipment.
