NINGHAO Machinery presents its Heavy Duty Thread Connection Rubber Joint with Union Ends for Pipelines. This joint is designed for secure and reliable pipeline connections.
The union is made from malleable iron. It provides a strong and stable connection.
The outer rubber is produced from EPDM. This material resists weathering and chemical exposure.
A reinforcing fabric made from nylon is included. It increases the joint’s durability.
The inner rubber is also made from EPDM. It ensures a tight seal and helps prevent leaks.
Note: For special material request other than standard specification, please indicate clearly on the inquiy or order list.
NINGHAO Machinery offers the Heavy Duty Thread Connection Rubber Joint with Union Ends for Pipelines. This product meets strict standards and performs in varied environments. Below are its key technical features:
Thread (ISO 7-1):
The joint uses ISO 7-1 threads. This standard gives a consistent and secure connection. It supports a stable fit.
Working Pressure (PN10/16):
The product is rated for PN10/16 pressure. It performs under both medium and high pressure. It maintains integrity during operation.
Temperature Range (0°C - 80°C):
The joint operates in temperatures from 0°C to 80°C. It works in both cool and warm conditions. It meets operational demands.
Vacuum Capacity (500MMHG):
The joint holds a vacuum capacity of 500MMHG. It keeps a reliable seal under low pressure. It aids in overall system stability.

NINGHAO Machinery produces the Heavy Duty Thread Connection Rubber Joint with Union Ends for Pipelines. The joint connects pipeline sections securely.
The joint is offered in several sizes. It is available from 1/2 inch to 3 inch. The DN values range from 15 mm to 80 mm. Neutral lengths are 200 mm or 240 mm.
Each joint uses a thread marked as Rc followed by the size. For example, a 1/2 inch joint uses Rc 1/2. Other sizes follow this pattern.
The joint allows 6 mm axial elongation. It gives 22 mm axial compression. It supports 22 mm transverse movement. It permits 40° angular deflection.
These specifications meet pipeline needs. The joint gives a stable connection and movement. The design meets requirements. Contact NINGHAO Machinery for details.
This chart shows safe operating pressure ranges at various temperatures. The grey envelope marks the allowable pressure. It guides design and safety decisions.
Coordinate Axes (Temperature and Pressure):
The horizontal axis shows temperature from -40°C to 120°C.
The vertical axis shows pressure from near 0 MPa to about 1.5–2.0 MPa.
Grey Area (Safe/Operational Range):
The grey area indicates allowed pressure ranges at each temperature.
Exceeding this area may cause safety risks.
Phase Change or Operational Boundaries:
The grey area may match the saturation curve for phase changes.
It sets the maximum working pressure for valves and fittings.
Engineering Applications and Safety Design:
Engineers use the chart to choose proper operating conditions.
It aids in equipment selection and risk assessments.
