A Complete Guide to Coalescing Filters

In industrial manufacturing and chemical processing, maintaining the purity of fluids and gases is critical. The presence of moisture, vapor, oil droplets, or solid particles in a system can not only compromise product quality but also damage downstream equipment. Coalescing filters are specialized devices designed to remove liquid droplets and vapor particles from fluids and gases. They operate by merging small droplets into larger ones, making contaminants easier to separate and discharge. This...

Guide to Selecting Oil & Gas Three-Phase Separators

In early oil and gas production facilities, three-phase separators are indispensable pieces of equipment for handling wellhead production. Their main function is to efficiently separate the mixed phases of oil, gas, and water, delivering single-phase fluids suitable for subsequent processing steps. Despite being considered standard equipment in industry specifications, the performance of three-phase separators in actual field operations often deviates from design expectations. Operational challenges...

Spiral Heat Exchanger Guide: Design, Benefits & Applications

Spiral heat exchangers are uniquely engineered heat transfer devices, composed of two metal plates wound in a spiral formation to create two separate concentric flow channels. This innovative design allows two fluids at different temperatures to exchange heat efficiently without any direct mixing. Structurally, the primary fluid enters through a flange at the front and exits at the top, while the secondary fluid enters from the top and exits at the rear. The spiral configuration of the internal...

Carbon Steel Storage Tank vs. Stainless Steel Storage Tank

In industrial production, storage tanks are core equipment for storing liquids, gases, and solid materials. The choice of material directly determines how long the equipment can be used, how high the maintenance cost is, and how safe it is. Carbon steel and stainless steel are currently the two most common materials for storage tanks, but many people are not clear about their differences, and even have some misunderstandings, for example, thinking that stainless steel is always better than carbon...

Abnormal Pressure in Multi-Media Filter: Causes & Solutions

Multi-media filters are essential components in industrial water treatment systems. They are widely used in pre-treatment processes, circulating water filtration, and other applications where high water quality is required. These filters rely on layers of different media, typically anthracite, sand, and garnet, stacked in decreasing particle size to achieve optimal filtration performance. Despite their robust design, pressure abnormalities are among the most frequent operational issues. Pressure...

Selection Guide for Underground and Aboveground Storage Tanks

In petrochemical projects, urban fuel supply systems, and various industrial facilities, the location and type of storage tank are critical decisions. In recent years, more projects have tended to adopt underground storage tanks, primarily to save surface space, improve visual aesthetics, and reduce exposure to external risks. However, an underground storage tank is not simply a tank buried in the ground. It fundamentally changes the structure of risk rather than eliminating it. This article analyzes...

A Complete Guide to Storage Tank Hydrostatic Testing

Hydrostatic testing of storage tanks, often referred to in the industry simply as a water test, is a mandatory and critical verification procedure conducted after tank fabrication and installation are completed. In simple terms, the process involves filling the tank with water and applying a specified pressure to verify its sealing performance, structural strength, and operational safety. The core objectives of hydrostatic testing can be understood at three levels. First is safety: filling the tank...

Spherical Storage Tanks: Design, Structure & Installation

Spherical Storage Tanks (commonly referred to as sphere tanks) are steel pressure vessels with a perfectly spherical shape, often compared to a giant soccer ball or watermelon. This design is widely used in petroleum refining, petrochemical processing, and liquefied product terminal storage, primarily for storing liquid or gaseous materials. Most sphere tanks feature a single-shell structure; however, when storing liquefied gases under low-temperature and low-pressure conditions, a double-shell...
