Product Description

LIANHE manufactures stainless steel pipeline components for water, gas, heating, air-conditioning, and compatible industrial fluid systems.

Available in SS304, SS304L, SS316, and SS316L, the products provide good corrosion resistance, mechanical strength, and long-term performance under suitable operating conditions.

D-type and S-type connection profiles are available to meet different piping-system and installation-tool requirements. Multiple sealing-ring materials can be selected according to the transported medium, working pressure, and temperature.

Key Features

• Stainless steel construction with good corrosion resistance

• D-type and S-type connection options

• SS304, SS304L, SS316, and SS316L materials

• CIIR, EPDM, PTFE, and NBR sealing-ring options

• PN16 nominal pressure

• Mechanically formed construction

• Multiple surface-treatment options

• Customized logos and product markings

• Export packaging for international delivery

The connection profile, sealing ring, material, pressure, temperature, and medium compatibility must be confirmed before ordering. D-type and S-type products may require different pressing tools and jaws.

Applications

Suitable for compatible applications in:

• Drinking-water systems

• Cold- and hot-water pipelines

• Wastewater systems

• Industrial water pipelines

• Heating and air-conditioning systems

• Commercial and residential buildings

• Hospitals and hotels

• Ships and marine installations

• Environmental protection equipment

• Oil and gas systems, subject to technical confirmation

Steam, gas, oil, and drinking-water applications require appropriate material, gasket, testing, and regulatory confirmation.

Product Testing

Available tests include:

• Hydrostatic Pressure Test

• Airtightness Test

• Negative-Pressure Test

• Pull-Out Test

• Cold- and Hot-Water Temperature-Cycling Test

• Hydrostatic Bending and Torsion Test

• Hydrostatic Vibration Test

• Hydrostatic Impact Test

The applicable test items and sampling ratios depend on the product specification, standard, and order requirements.

Quality Control

LIANHE applies in-process and final inspection throughout production:

1. Inspect raw-material grade, outside diameter, and wall thickness.

2. Check length and pipe-end condition after cutting.

3. Inspect socket dimensions and wall thickness after forming.

4. Check weld dimensions and surface quality where applicable.

5. Inspect product dimensions after heat treatment.

6. Verify surface quality after polishing or pickling.

7. Perform hydraulic-pressure and airtightness tests.

8. Check product markings, quantities, and packaging before shipment.

Inspection Documents

Available documents include:

• EN 10204 3.1 Material Test Certificate

• Raw-Material Inspection Certificate

• Dimensional Inspection Report

• Hydraulic and Airtightness Test Report

• Radiographic Testing Report, when applicable

• Third-Party Inspection Report

Production Capability

Our factory is equipped with automatic pipe-welding lines, laser-cutting machines, forming machines, CNC lathes, pipe-bending equipment, polishing machines, grooving equipment, hydraulic and airtightness testing units, laser-marking machines, and export-packaging equipment.
