Description
When it comes to pipeline construction, commissioning, and maintenance and integrity management, perfection is never optional. Each pigging run relies on dependable components that precisely evaluate the internal dimensions of the pipeline, identify limits and ensure safe pig passage before deploying valuable inspection instruments or cleaning pigs. The aluminum gauge plate is one of the simplest, yet most crucial, components in effective pigging operations.
PETROL STEEL CO., LTD has been producing Aluminum Gauge Plates for Pipeline Pigging for over 20 years for clients worldwide. We have worked with pipeline EPC contractors, oil & gas operators, engineering firms, pipeline maintenance specialists, pigging service providers and industrial distributors. For thousands of shipments to worldwide energy markets, our principle has been the same: every gauge plate must work exactly as specified when put in the field.

Unlike suppliers that just produce metal discs according to plans, PETROL STEEL understands the behavior of aluminium gauge plates during real pigging operations. The gauge plate is the first sign that the pipeline is ready for intelligent pigging, geometry inspection, hydrotest preparation, commissioning or normal maintenance. A badly made gauge plate might cause false deformation, wrong inspection results, costly operational delays, or even expensive pigging failures. So, dimensional accuracy, material consistency, machining quality and reliable delivery are equally crucial.
Our engineering team has over twenty years of expertise making pipeline goods. Our international sales specialists have more than 15 years of export experience and know the procurement standards of global EPC contractors and industrial buyers. Our Quality Inspection Department has decades of practical inspection experience, including dimension check, machining accuracy, material traceability and shipment inspection. Behind us is our skilled logistics team, and all shipments are carefully planned to ensure they arrive safely and swiftly at project sites.

Our Aluminum Gauge Plate Specifications
Diameter (OD): Usually 90%–95% of the minimum pipe ID; 95% ID is the default for pre-ILI/ pre-commissioning runs. Tolerance typically ±0.5% or ±1 mm.
Thickness:
2”–14” pigs: 1/4" (6.35 mm) standard, bevelled edge, non-slotted.
16”–48” pigs: 3/8” (9.5 mm) standard, slotted; other common options 1/8” (3.2 mm) and 1/2” (12.7 mm). EPC specs often state min. 6 mm.
Edge & slots: The leading edge has a 45° chamfer/bevel; plates ≥16” often have 8 / 12 / 16 radial slots (~25.4 mm deep) cut from the circumference to localize buckling and identify defect orientation.
Marking: Unique ID stamped/painted for post-run inspection record.

One of the reasons why our international customers continue to come back to PETROL STEEL is our inventory capability. Standard sizes and specifications are kept in stock year-round, with shipment within one week for urgent project needs. For custom production, our normal manufacturing schedule is typically four to five weeks so customers can maintain project schedules without undue procurement risk.
At PETROL STEEL quality commitment is more than a catchphrase. Every Aluminium Gauge Plate undergoes a stringent dimensional examination before to dispatch. We are very convinced that every gauge plate shipped to our customers must be entirely qualified. This is why we openly pledge that if one Aluminum Gauge Plate fails to fulfil the stipulated quality and dimensional criteria, PETROL STEEL will pay twofold compensation as per our quality guarantee. With over twenty years of foreign exports, we have a record of zero customer claims in our business, demonstrating the stability of our factory management and customer support.

Equally crucial is the selection of aluminum alloy to achieve reliable field performance. Aluminum gauge plates are chosen for their lightweight, excellent machinability, resistance to corrosion and the predictable deformation as it passes through pipeline restrictions. The gauge plate gives obviously visual evidence of internal diameter reductions, weld penetration problems, dents, mechanical deformation, valve limits or foreign object interference during pigging operations. This enables pipeline operators to make sound engineering decisions prior to introducing costly intelligent pigs or inspection equipment.
PETROL STEEL is a manufacturer of Aluminum Gauge Plates for a variety of pipeline applications, including crude oil pipelines, natural gas transmission systems, refined petroleum pipelines, offshore pipelines, LNG facilities, petrochemical plants, refinery projects, water transmission systems, district energy networks, chemical processing plants, and industrial pipeline installations. Our devices are designed to provide reliable dimensional verification under difficult operating conditions, whether your project is a new pipeline start-up or an ongoing pipeline maintenance.
Modern pipeline projects face international engineering standards and rigorous procurement procedures. Our export team has vast experience in assisting customers with commercial documentation, inspection reports, packing lists, certificates of origin, mill certificates where applicable, dimensional inspection reports, third-party inspection arrangements, custom packaging, and worldwide logistics solutions. We understand the documentation requirements of EPC contractors, engineering consultants, inspection companies and end users so as to ensure a seamless purchase process from bid to final delivery.
Another key advantage is the flexibility of manufacturing. In addition to conventional aluminum gauge plates, PETROL STEEL may create customized dimensions depending on customer drawings, pig body dimensions, pipeline nominal diameters, wall thickness, project specifications or specific pigging techniques. Precision CNC machining, good surface quality, and the reproducibility of production batches ensure dimensional precision. Each finished product is inspected before packing to ensure that it is consistent with the specifications of customers.

Our customer base includes international EPC contractors, pipeline construction companies, pipeline inspection contractors, pigging service companies, oil companies, gas transmission operators, refinery maintenance contractors, industrial distributors, engineering procurement companies and project management companies. Many customers cooperate with PETROL STEEL because they value not only the quality of the product but also the quick response, the professional technical support, the reliability of the delivery schedules and the long-term partnership.
As pipeline integrity management becomes more essential globally, procurement experts are paying less attention to the lowest price and more attention to supplier reliability. Dimensional flaws, irregular machining, bad packaging or unreliable transportation can lead to unexpected project delays that cost far more than the product itself. PETROL STEEL controls these risks via disciplined factory management, extensive inspection procedures, skilled international logistics coordination and quick after-sales service.
We provide technical support before, during and after each order. Our engineering consultants help customers to choose the right gauge plate size, aluminum material grades, machining tolerances and project-specific solutions. Sales engineers work closely with the production, inspection and logistics teams to guarantee that each order moves efficiently from the initial inquiry to the final delivery. After delivery, customers can always get rapid technical support as needed.
For over 20 years, PETROL STEEL has been serving the international pipeline sector and has developed long-term ties with its customers based on reliability, transparency, expert knowledge and continuous product quality.
