J-VALVES Basket-Type Strainers: High-Performance Pipeline Filtration Solutions Meeting JB/T 7538-1994 Standard

In modern industrial pipeline systems, pipeline basket-type strainers serve as critical components to ensure medium purity, equipment safety, and stable system operation. As a professional manufacturer of industrial valves, J-VALVES has been dedicated to providing high-quality filtration equipment that complies with both international and national standards since its establishment in 2009.

I. Introduction to JB/T 7538-1994 Standard

JB/T 7538-1994 is an industrial standard under China’s machinery sector specifically for pipeline-used basket-type strainers. It defines the product’s design requirements, structural dimensions, manufacturing processes, and testing methods.

The core purposes of this standard are:

1. To guarantee the reliability of strainers in environments with high pressure, high temperature, and corrosive media;

2. To unify the technical specifications of domestic basket-type strainers;

3. To enhance filtration efficiency and maintenance convenience.

Key technical requirements include:

1. Shell materials: Carbon steel, stainless steel, alloy steel, etc.

2. Nominal pressure rating: PN20 ~ PN100.

3. Filtration precision: Customizable based on medium characteristics, ranging from 20 mesh to 400 mesh.

4. Connection standards: In line with GB/T or ANSI flange connection specifications.

II. Structural Features of J-VALVES Basket-Type Strainers

J-VALVES designs and manufactures its products in strict adherence to the JB/T 7538-1994 Standard, and its products boast the following advantages in structure and performance:

1. High-strength shell design

   It adopts precision welding and fully automatic spraying technology, ensuring the equipment can withstand pressure without deformation for a long time and featuring excellent surface anti-corrosion performance.

2. Removable screen structure

   The filter basket allows for quick disassembly and assembly, facilitating cleaning and maintenance. It is particularly suitable for working conditions that require frequent maintenance.

3. Low-pressure loss design

   The internal streamlined structure reduces fluid resistance, maintaining efficient system operation while ensuring filtration effectiveness.

4. Multiple material options

   A variety of materials are available, including carbon steel, stainless steel (304/316), and duplex steel, to meet the needs of different media and working conditions.

5. Customization services

   Shell size, flange standards, and filter mesh count can be customized according to customers’ working conditions to achieve precise matching.

III. Application Fields

J-VALVES basket-type strainers are widely applied in:

1. Petrochemical pipelines: Used in crude oil, fuel oil, and lubricating oil systems;

2. Power generation and thermal energy systems: Protecting cooling water pipelines and heat exchange equipment;

3. Water treatment industry: Applied in reverse osmosis pretreatment and circulating cooling water systems;

4. Pharmaceutical and food industries: Used to remove liquid impurities and ensure product purity.

IV. Quality and Service Guarantee

J-VALVES has a comprehensive quality management system. All strainers undergo pressure testing and sealing testing to ensure compliance with the requirements of JB/T 7538-1994 and international standards.
