Application Scenarios:
● High‑temperature and high‑pressure main steam pipelines in power plants, high‑pressure process pipelines for refineries and petrochemical plants, long‑distance oil‑gas gathering and transmission trunk lines, diameter transition sections for inlet and outlet of pressure vessels. Classified as special‑equipment pressure‑bearing pipe fittings.

Application Scenarios:
● Mainly used for process pipelines in petroleum, refining and natural gas industries. Different from conventional spectacle blinds, this three‑hole blind plate is equipped with 3 built‑in process holes while isolating the main pipeline, integrating multiple functions including isolation, pressure relief, condensate drainage, sampling and pressure measurement.
