Stainless Steel Press 90° Long Elbow – S Type

Product Description

The LIANHE Stainless Steel Press 90° Long Elbow S Type is designed to change the direction of a compatible stainless steel pipeline by 90 degrees. Its extended bend profile provides a smoother directional transition than a compact elbow, helping maintain stable flow through water, gas and industrial piping systems.

Manufactured from mechanically formed stainless steel pipe, the elbow combines dimensional accuracy, corrosion resistance and reliable joint performance. The S-type press socket allows fast installation without conventional threading or on-site welding.

Product Advantages and Applications

Core Advantages

1. Structural strength: The mechanically formed elbow provides strength and dimensional stability for compatible piping installations.

2. Corrosion resistance: SS304, SS304L, SS316 and SS316L options are available for different operating environments.

3. Long service life: Stainless steel construction provides durability and can reduce replacement requirements.

4. Smooth flow transition: The long 90-degree bend supports a smoother change in flow direction.

5. Seismic performance: The mechanical press joint is suitable for appropriately designed systems exposed to vibration or movement.

6. Environmentally responsible material: Stainless steel is durable and recyclable.

7. Fast installation: The press connection reduces the need for conventional threading or on-site welding.

8. Concealed installation: The compact connection is suitable for exposed or embedded piping layouts, subject to applicable requirements.

9. Cost efficiency: Fast installation and limited maintenance can reduce overall piping-system costs.

10. Wear resistance: The stainless steel body provides durability under suitable operating conditions.

11. Hygienic applications: Compatible materials can be used in drinking-water systems that meet relevant sanitary requirements.

12. Reliable sealing: The correct pipe, gasket and press tool provide a secure and leak-resistant joint.

13. Accurate 90-degree routing: The elbow enables pipelines to change direction in restricted or planned pipe layouts.

Application Fields

The stainless steel press 90° long elbow can be used in engineering projects, ships, commercial buildings, residential buildings, hospitals, hotels, environmental protection facilities, heating installations and air-conditioning systems.

It is suitable for compatible water, gas, direct drinking-water, environmental protection, heating, air-conditioning and industrial water piping systems.

For steam, oil, gas or other demanding media, the stainless steel grade, gasket material, operating pressure and temperature should be confirmed before ordering.

Quality Control System

Dedicated quality-control personnel perform in-process and final inspections. Products are inspected before shipment according to the applicable product specification and order requirements.

Eight-Step Quality Control Process

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

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

3. Inspect the socket, outside diameter and wall thickness after machining.

4. Check the elbow-forming area, weld dimensions and surface condition where applicable.

5. Inspect the surface, dimensions, bend shape and socket after heat treatment.

6. Check the finished surface after polishing or pickling.

7. Perform the applicable hydraulic and airtightness tests.

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

Testing and Delivery Inspection
