Rubber Expansion Joints
WTX 90° Flexible Rubber Expansion Elbow
The WTX 90° Flexible Rubber Expansion Elbow combines a directional pipe bend with an elastomeric flexible connection for installations where vibration isolation and controlled movement are required within a compact elbow arrangement. Mingchao’s catalog covers DN50–DN300 and three documented WTX operating classes, with custom dimensions, flange interfaces and material configurations available to approved project drawings.

Project Configuration
Mingchao can customize the product configuration based on the technical information, operating conditions and dimensional data you provide. Final configuration can be reviewed and manufactured to the approved project drawing.
WTX 90° Flexible Rubber Expansion Elbow — Overview
The WTX 90° Flexible Rubber Expansion Elbow combines a directional pipe bend with an elastomeric flexible connection for installations where vibration isolation and controlled movement are required within a compact elbow arrangement. Mingchao’s catalog covers DN50–DN300 and three documented WTX operating classes, with custom dimensions, flange interfaces and material configurations available to approved project drawings.
The catalog values are source references. Final suitability and operating limits require the selected material, dimensions, connection and project conditions to be confirmed.
90° Direction Change with Flexible Isolation
This connection geometry combines flexible isolation with the product-specific interface shown in the catalog. Selection must consider the complete piping arrangement and approved drawing.
WTX-I, WTX-II & WTX-III Operating Classes
Catalog operating classes: WTX-I 1.0 MPa working, 2.0 MPa burst, 53.3 kPa vacuum; WTX-II 1.6 MPa working, 3.2 MPa burst, 86.7 kPa vacuum; WTX-III 2.5 MPa working, 4.5 MPa burst, 100 kPa vacuum. These are catalog references and remain material-, size- and configuration-dependent. Catalog applicable temperature is -15°C to 115°C; special -30°C to 250°C conditions require specific configuration confirmation.
Unified DN50–DN300 Engineering Specifications
Unified engineering fields: DN; NPS; Elbow Angle; Face-to-Face / Geometry; Movement; WTX Operating Class; Working Pressure; Burst Pressure; Vacuum; Temperature; Rubber Compound; Reinforcement; Flange Standard; Flange Material; Medium; Customer Drawing; Custom Angle; Custom Dimensions. Catalog numeric fields are exact; other requirements are project-specific or factory-confirmation fields.

Catalog movement values are individual references; combined movement requires engineering confirmation.
Movement in a Flexible Elbow Geometry
Connection geometry and interface requirements must be stated on the customer or project drawing. Do not assume an unspecified thread, flange or angle.
Flange & Connection Customization
Catalog movement values are individual references and must not be combined simultaneously without engineering confirmation.
Rubber Compound & Service-Medium Selection
Catalog operating classes: WTX-I 1.0 MPa working, 2.0 MPa burst, 53.3 kPa vacuum; WTX-II 1.6 MPa working, 3.2 MPa burst, 86.7 kPa vacuum; WTX-III 2.5 MPa working, 4.5 MPa burst, 100 kPa vacuum. These are catalog references and remain material-, size- and configuration-dependent. Catalog applicable temperature is -15°C to 115°C; special -30°C to 250°C conditions require specific configuration confirmation.
Pressure, Burst, Vacuum & Temperature
Material selection depends on medium, concentration, temperature, pressure and environment. Catalog materials are references, not universal compatibility guarantees.
Custom Angle, Length & Drawing-Based Fabrication
Drawing-based custom geometry is available subject to engineering and manufacturability review. Custom geometry does not imply unlimited pressure, temperature or movement.
Pump, Equipment & Industrial Applications
Typical applications require confirmation of pressure, temperature, medium, movement, supports and connection details.
Anchors, Supports & Pressure Thrust
Internal pressure creates thrust. Rubber joints do not replace anchors, guides or independent pipe/equipment supports. Installation must avoid forced alignment and torsional preload.
