Successful Supply of ASTM A312 TP316L Stainless Steel Seamless Pipes For Malaysia Chemical Plant Project

Project Overview

In 2025, our company successfully supplied high-quality ASTM A312 TP316L stainless steel seamless pipes for a chemical processing plant project in Malaysia. The customer required corrosion-resistant piping materials for transporting aggressive chemical media under high-temperature and high-pressure operating conditions.

Due to the demanding working environment, the client needed a reliable supplier who could provide stainless steel pipes with excellent corrosion resistance, strict dimensional control, and complete quality documentation.

Customer Requirements

The Malaysia customer was looking for stainless steel seamless pipes with the following requirements:

• Product: Stainless Steel Seamless Pipe
• Material Grade: ASTM A312 TP316L
• Standard: ASTM A312 / ASME SA312
• Size Range: OD 21.3 mm – 219.1 mm
• Wall Thickness: SCH10S – SCH40S
• Length: 6 meters per piece
• Surface Finish: Pickled & Annealed
• Inspection Requirement: EN 10204 3.1 Material Test Certificate

The main challenges included:

1. Excellent resistance against chloride corrosion and chemical media.
2. Stable mechanical properties under continuous operation.
3. Strict control of chemical composition and surface quality.

Our Solution

Based on the customer's operating conditions, we recommended 316L stainless steel seamless pipe because of its low carbon content and enhanced corrosion resistance.

Our production team controlled every stage of manufacturing:

1. Raw Material Control

All raw materials were supplied with heat number identification and chemical composition verification to ensure compliance with ASTM A312 requirements.

2. Precision Manufacturing

The pipes were produced through a seamless manufacturing process, providing:

• Uniform wall thickness
• High pressure resistance
• Smooth internal surface
• Excellent dimensional accuracy

3. Heat Treatment & Surface Treatment

After production, all pipes underwent:

• Solution annealing treatment
• Pickling and passivation
• Ultrasonic testing (when required)

This improved corrosion resistance and ensured long service life.

4. Quality Inspection

Before shipment, our quality team performed:

• Chemical composition analysis
• Tensile testing
• Hardness testing
• Dimensional inspection
• Hydrostatic testing
• Visual inspection

All inspection results were documented in the EN 10204 3.1 certificate.

Project Results

The stainless steel pipes were delivered successfully to Malaysia and installed in the customer's chemical processing system.

The customer highly appreciated:

✔ Stable product quality
✔ Accurate dimensions
✔ Complete inspection documents
✔ On-time delivery
✔ Professional technical support

After the successful first order, the customer continued cooperation with us for additional stainless steel pipe requirements.
