Recommended Continuous Operating Temperature Range Note: The values below are general recommended continuous temperature ranges.Actual performance depends on compound formulation, media compatibility, pressure, and service conditions. Material Abbreviation Continuous Temperature Range Typical Applications Nitrile Rubber NBR –40°C to +100°C Hydraulic oil, fuel systems, general industrial oils Hydrogenated Nitrile HNBR –40°C to +150°C Automotive systems, high-temperature […]

In mechanical design and manufacturing, you often encounter tolerances marked on technical drawings, such as Φ20±0.02, 20+0.01/−0.03, or H7/g6. Almost everyone who has looked at such drawings has asked the same questions: Why are some tolerances so strict? Why are some dimensions given default tolerances, while others are specified individually? Why are geometric tolerances like

Gaskets are commonly used components in industrial equipment. But have you installed them properly? Incorrect installation can lead to gasket damage and even hazardous situations. Below is a step-by-step guide to ensure correct gasket installation. Tools You’ll Need for Installation Before starting, make sure to prepare the following tools: A calibrated torque wrench, hydraulic tightening

1. What is Sampling? Sampling refers to the process of measuring and recording a continuous-time analog signal at fixed intervals, thereby converting the continuous-time signal into a discrete-time sequence. Sampling transforms the time axis from a continuous domain into an integer-indexed domain, allowing the signal to be processed by digital systems. The sampling rate is

In the chemical industry, measuring the liquid level in sodium hydroxide (caustic soda) storage tanks has long been a challenging issue. Due to its strong corrosiveness, tendency to crystallize, and steam emissions, traditional instruments often “fail” in such conditions. In this article, we’ll explore how to address this challenge. Key Physical Parameters for Monitoring Sodium
