Malaysia Palm Oil Refinery High-pressure Process Pipeline Project

Project Overview

This project is located in a large palm oil deep processing industrial park in Sabah, Malaysia. The process pipeline network supports new refining production lines for high-pressure sealed transportation of hot palm oil and oil derivatives.The tropical environment features heavy rainfall, high humidity and salt spray. Pipes operate continuously under high temperature. The project follows British BS standards and Malaysian industrial specifications, with strict requirements on heat resistance, weather corrosion resistance and weldability. After quotation comparison, sample testing and factory audit, Pengyuan Steel was selected as the main seamless pipe supplier.

Project Challenges

1. Alternating outdoor and indoor service in tropical climate; pipes must resist humid salt spray corrosion and withstand medium at around 110℃;

2. Non-stop production requires excellent anti-creep performance to avoid deformation and leakage under long-term pressure;

3. Mass on-site prefabricated welding demands precise dimensional tolerance and flat pipe ends;

4. All official documents must be issued in English and support on-site inspection by local Malaysian third-party surveyors.

Supplied Products

Product: Grade 20 / ASTM A106 Gr.B seamless process steel pipesSize: OD168.3mm～OD406.4mm, wall thickness 6.2mm～12.7mmTotal quantity: 1,530 metric tonsStandards: ASTM A106 Gr.B, GB/T 8163

Pengyuan Solution

1. High-quality carbon steel billets adopted. Optimized rolling and heat treatment enhance structural stability under high temperature;

2. Precision facing on pipe ends with tight tolerance control to simplify field welding assembly;

3. Every pipe passes hydrostatic test and ultrasonic inspection. Thorough surface cleaning reduces corrosion risks;

4. Goods delivered in five batches by sea container to match refinery equipment installation timeline;

5. Complete English mill test reports and NDT certificates provided to coordinate third-party inspection.

Project Result

All steel pipes arrived at Sabah Port on schedule and passed joint acceptance by EPC contractor and end client. After commissioning, the palm oil production line runs smoothly. The process pipelines achieve expected performance on heat resistance and anti-corrosion. This project builds stable long-term cooperation with local edible oil engineering contractors.
