Key Takeaways
- This guide profiles the top modular process skid makers in China — Lmart, Rongteng, Bluesky, YADA, DFC, FAB and CIMC ENRIC.
- The biggest quality differentiator is who fabricates the pressure vessels and heat exchangers on the skid in-house versus assembling bought-in parts.
- Pin down the package boundary (piping, E&I, controls) and match the fabricator's ASME/PED code scope to your jurisdiction.
- Require a witnessed FAT and a complete data book before shipment, and confirm the module ships within your transport envelope.
Short answer: The leading modular process skid manufacturers in China include Lmart (Suzhou Lmart Energy Equipment), Rongteng, Bluesky New Energy, YADA Green Energy, DFC, FAB, and the HK-listed giant CIMC ENRIC. To choose the right one, verify who fabricates the pressure vessels and heat exchangers on the skid in-house, confirm the package boundary (piping, E&I, controls), check ASME/PED code scope, and require a full FAT and data book before shipment.
Modular, skid-mounted process equipment lets oil & gas, LNG/LPG, CO2 and chemical operators compress schedule and de-risk site work by shifting fabrication, assembly and testing into a controlled shop. The package arrives as a tested module, not a pile of parts. But "skid builder" covers everything from a genuine code-vessel fabricator to a shop that only bolts bought-in components onto a frame. This guide explains the selection criteria that actually matter, then profiles the manufacturers so EPCs and end users can shortlist with confidence.
What a "Modular Process Skid" Actually Is
A process skid is a pre-engineered package where the core equipment — pressure vessels, heat exchangers, pumps or compressors, instrumentation and interconnecting piping — is mounted on a structural steel frame (the "skid"), wired, tubed and tested as a single transportable unit. Common types include:
- Process skids — separation, filtration, metering, injection, dosing packages
- LNG / LPG skids — regasification, pump, BOG handling, fuel-gas skids
- CO2 treatment / capture skids — dehydration, compression, purification trains
- Refrigeration & gas compression skids — ammonia/hydrocarbon refrigeration packages, BOG compression
The value of modularization is realized only if the shop can hold code compliance and quality across all of those disciplines — which is exactly where fabricators differ.
Selection Criteria: How to Choose a Skid Manufacturer
Before comparing brands, define what you are actually buying. Use these six criteria in your RFQ and technical bid evaluation.
1. Package boundary (scope of supply)
Nail down where the skid stops. Does the price include interconnecting piping, valves, the instrument air/tubing, junction boxes and cable trays, the local control panel and PLC, or is it "mechanical only"? A cheap number often hides a narrow boundary. Specify battery-limit connections, E&I scope and who does loop checks.
2. In-house vessel and heat-exchanger fabrication
This is the single biggest quality and cost differentiator. A fabricator that builds the pressure vessels, columns, separators and heat exchangers on the skid in its own shop controls materials, welding, NDE, PWHT and code stamping under one roof — and owns the interface between the vessel and the package. A pure assembler buys those items in and manages sub-suppliers, adding cost, lead time and interface risk.
3. Code and certification scope
Match the fabricator's certifications to your project's jurisdiction. For pressure-containing equipment on the skid, look for ASME BPVC Section VIII (U-Stamp), PED 2014/68/EU (CE marking) for the EU, EN 13445 or GB/T 150 design codes, plus ISO 9001 quality management and classification-society approval (e.g. DNV) for marine/offshore.
4. Transport and shipping readiness
Modular only works if the module actually ships. Confirm the shop designs to your transport envelope (road, rail, breakbulk, open-top or flat-rack container), addresses lifting/tie-down lugs, shipping-load stress checks, and sea-fastening or weatherproofing for the module.
5. FAT and documentation
Require a Factory Acceptance Test at the shop — hydrotest, pneumatic/leak test, functional and, where relevant, string testing — witnessed or by hold-point. Equally important is the data book: material certs (EN 10204 3.1/3.2), weld maps, NDE reports, PWHT charts, ITP sign-offs and as-built drawings. A thin data book is a warning sign.
6. Engineering integration
The best skid outcomes come from single-source engineering + fabrication, where 3D modelling, stress/piping analysis, and vessel/HEX design live in the same organization that welds the module. This removes the drawing-to-shop handoff errors that plague multi-vendor packages.

Frequently Asked Questions
How do I define a skid package boundary?
Define it explicitly in the RFQ as a battery-limit list: the mechanical equipment on the frame, all interconnecting piping and valves within the skid, the E&I scope (junction boxes, cable tray, tubing, local panel/PLC), the coating and insulation, and the exact tie-in points where the skid connects to site utilities and process lines. State who is responsible for loop checks, commissioning support and any off-skid items. A clear boundary is the only way to compare quotes fairly, because "skid price" means very different scopes from different vendors.
Why does in-house vessel fabrication matter for a skid?
Because the pressure vessels and heat exchangers are usually the technical and cost core of the module. When one company designs, welds, NDE-tests, stamps and then integrates those vessels onto the skid, it owns the vessel-to-package interface — nozzle orientations, supports, thermal growth, piping loads — with no drawing handoff to a sub-supplier. That means fewer interface errors, tighter schedule control, a single point of quality accountability, and typically lower delivered cost than an assembler who buys the vessels in and marks them up.
What certifications should a modular process skid manufacturer hold?
For pressure-containing equipment, look for ASME BPVC Section VIII (U-Stamp) for ASME jurisdictions, PED 2014/68/EU with CE marking for the European market, and design codes such as EN 13445 or GB/T 150. Add ISO 9001 for quality management and, for marine or offshore packages, classification-society approval such as DNV. Match the certification to where the skid will be installed and operated — a cert the shop cannot demonstrate on your equipment class is not useful.
Should I choose a Chinese skid fabricator or an international EPC/skid house?
It depends on where your project's value and risk sit. International package houses suit turnkey, heavily-instrumented or brand-approval-driven modules, at higher cost and longer lead time. Chinese fabricators are strong when the module's core value is in certified pressure vessels and heat exchangers, where integrated single-shop fabrication delivers competitive cost and schedule. For engineering-intensive process/LNG/CO2 skids, a code-vessel fabricator that also integrates the skid often gives the best balance.
What should be in the skid data book at FAT?
A complete data book includes material certificates (EN 10204 3.1/3.2), the approved ITP with signed hold/witness points, weld maps and welder qualifications, NDE reports (RT/UT/PT/MT), PWHT charts where required, hydrotest/leak-test records, the functional/FAT test report, coating and insulation records, and as-built drawings plus the vessel code data reports (e.g. ASME U-1/U-2 forms). Insist on reviewing the data book structure before award — it tells you how the shop actually controls quality. ---
