TIANYU Steel Fabricated Butt-Welded T-Type Strainer

In industrial fluid conveying systems, T-type strainers are key devices for ensuring pipeline cleanliness and long-term equipment operation. TIANYU steel fabricated butt-welded T-type strainers, with internationally standardized design, diverse adaptability and reliable filtering performance, are widely used in impurity interception for fluid pipelines, providing effective protection for downstream equipment. The following details the product overview, key parameters, features, manufacturing processes, advantages and application fields.

1. Product Overview

TIANYU steel fabricated butt-welded T-type strainer is an impurity interception device designed for fluid pipeline systems. It guides fluid through the filter screen via a T-type structure to efficiently trap solid particles, preventing downstream pumps, valves, heat exchangers and other equipment from failure due to blockage or wear. The product adopts a fabricated manufacturing process, supporting various connection methods such as butt welding and flanging, and is compatible with industrial pipelines of different diameters and pressure levels. It is a core component for fluid purification in petroleum, chemical, municipal and other industries.

2. Key Attribute Parameters

1. Size and Pressure

Nominal Diameter (DN): Covers DN15-DN1000, meeting the filtering needs from small-caliber precision pipelines to large industrial pipelines.
Pressure Rating: 150lb-900lb (corresponding to nominal pressure PN20-PN150), suitable for medium and high-pressure fluid systems, ensuring stable operation under rated pressure.

2. Material Selection

Body and End Cover: Carbon steel (such as A234 Wpb, Wpbs), stainless steel (304, etc.) and alloy materials (WCB, WC1, WC6, CF8, etc.) are used. The material can be selected according to the medium characteristics—carbon steel is suitable for neutral media such as water and oil, while stainless steel and alloy materials are suitable for corrosive or high-temperature media.
Filter Screen: Standard 304 stainless steel, with good corrosion resistance and strength, ensuring that long-term filtration is not easy to deform or break.
Gasket: Asbestos sheet is used, suitable for normal to medium temperature working conditions, ensuring no medium leakage during filtration.

3. Connection and Testing

Connection Method: Supports butt welding and flange connection (among which butt welding can reduce pipe consumption and improve pipeline integrity), suitable for different installation scenarios.
Testing Standard: Factory inspection is carried out according to API 598 standard, with static pressure test pressure of 2.4-6.0MPa, ensuring that the valve body strength and sealing performance meet the standards.

4. Working Condition Adaptation

Applicable Media: Various fluids such as water, oil and steam.
Applicable Temperature: Up to 300℃, meeting the needs of most industrial normal to medium temperature working conditions.

Product Overview

3. Product Features

1. Internationally Standardized Design

The product design, face-to-face distance and connection all follow ANSI B 16.34 standard, and the testing conforms to API 598 specification, ensuring compatibility with internationally general pipeline systems and reducing the adaptation risk of cross-system installation.

2. Strong Adaptability with Diverse Connection Modes

It provides four connection modes A, B, C and D, covering two mainstream connection methods of butt welding and flanging. It can flexibly adapt to different pipeline system equipment, and can be installed without additional adjustment of pipeline structure, reducing engineering transformation costs.

3. Efficient Filtration with T-Type Structure

The T-type structure designed according to the characteristics of fluid flow makes the fluid form a reasonable flow direction when flowing through the filter screen. Impurities are more easily intercepted under the action of inertia and gravity. The filtration efficiency is better than that of traditional straight-through strainers, and the filter screen is easy to disassemble and assemble, facilitating later maintenance.

4. Wide Range of Size Coverage

The diameter range from DN15 to DN1000 can meet the filtering needs from precision instrument pipelines to large industrial main pipelines, without replacing the filtering scheme due to diameter differences, improving system compatibility.

4. Manufacturing Process

TIANYU steel fabricated butt-welded T-type strainer adopts a fabricated manufacturing process, with core processes as follows:

Material Pretreatment: Cut carbon steel or stainless steel pipes and plates according to design requirements to ensure the dimensional accuracy of raw materials and lay the foundation for subsequent assembly.
Structural Welding: Assemble the valve body, end cover, filter screen frame and other components into shape through precision welding technology. Strictly control the welding parameters for butt-welded joints to ensure the strength and tightness of the weld, reducing fluid resistance.
Filter Screen Assembly: The 304 stainless steel filter screen is cut and stamped into shape, then accurately docked with the internal structure of the valve body to ensure uniform gap between the filter screen and the valve body, avoiding impurity bypass.
Inspection and Acceptance: Each strainer undergoes factory inspection according to API 598 standard, with static pressure test pressure of 2.4-6.0MPa to check whether the valve body and sealing parts leak; at the same time, the strength of the filter screen is verified to ensure that it does not deform or break under rated pressure.

5. Product Advantages

1. Outstanding Equipment Protection Capability

The 304 stainless steel filter screen can effectively intercept mechanical impurities such as rust, welding slag and gravel in the pipeline, reduce the risk of blockage and wear of downstream pumps, valves and heat exchangers, prolong the service life of equipment and reduce the number of maintenance shutdowns.

2. Low Installation and Maintenance Costs

Butt welding connection can reduce pipe consumption, and flanged connection is convenient for quick disassembly and assembly; the T-type structure design enables the replacement of the filter screen without disassembling the entire pipeline, with short maintenance time and low labor cost.

3. Wide Adaptability to Working Conditions

Diverse material selection and wide pressure and temperature ranges enable it to adapt to various media such as water, oil and steam. It can operate stably whether it is neutral fluid or slightly corrosive medium, reducing the frequency of equipment replacement due to medium characteristics.

4. Conformity to International Specifications and Strong Universality

Following international standards such as ANSI and API, it can be directly applied to imported equipment supporting pipelines or export projects, without additional standard conversion, reducing the technical communication cost of transnational projects.
