Consolidating Fragmented AC Piping Supply Chains Into
Production-Ready Kits.
Guangzhou Haiben Refrigeration Parts Co., Ltd. serves AC assembly manufacturers. We do not just supply single components; we integrate Y-joints, cut-to-length copper pipes, filter driers, charging valves, and vibration eliminators into complete piping kits based on your BOM. We bundle the required certification documentation, delivering a unit that is ready for your production line without the need for multi-party coordination. Our supply chain is backed by a manufacturing system equivalent to that of leading AC brands, and we have been deeply engaged in the refrigeration parts industry since 2013.
From Refrigeration Parts to Piping Kit Aggregation
Guangzhou Haiben Refrigeration Parts Co., Ltd. was established in 2013, starting with cut-to-length copper pipes for HVAC components. Over the past decade, our client base has expanded from domestic OEMs to international assembly plants and regional distributors. We have developed our own strict criteria for the actual application scenarios, common failure points, and documentation requirements of piping components during the assembly process.
We have narrowed our product scope to focus solely on AC piping lines—because only through focus can we truly control specification matching, documentation chains, and delivery schedules. Today, the role of "Haiben" is an aggregator and delivery coordinator for piping kits, rather than a mere manufacturer of individual parts.
Top-tier Brand Equivalent Manufacturing System
Our supply chain originates from the manufacturing systems that support top-tier AC brands. This means that every module in the kit—its material standards, machining precision, and inspection records—complies with the requirements these brands demand of their Tier 1 suppliers, not the random assembly of generic parts found on the open market. "Equivalent Quality" is not a marketing slogan; it translates to specific incoming inspection standards, welding process stability, and batch consistency.
Manufacturing: Top Brand Supply System
Piping components, filters, and valves are sourced from manufacturing plants that have long served leading AC brands. Process standards and inspection procedures align with brand supply chains. The batch stability of copper pipe cutting, flaring, and welding is supported by traceable inspection records.
Compliance: Certified Docs Included
Modules requiring certification, such as filter driers and charging valves, are purchased from UL/CE certified manufacturers, with certificates available upon delivery. RoHS/REACH declarations for insulation materials are provided according to target market requirements, ensuring a complete customs clearance document chain.
We Provide Piping Units Ready for the Assembly Line, Not Just Individual Parts
Why "Kits" Instead of "Piece-by-Piece Ordering"
The reality for assembly plants purchasing piping components is this: Y-joints come from one factory, copper pipes from another, and filters and charging valves each have their own suppliers. Every factory has different lead times, MOQs, document formats, and inspection standards. The client has to assemble these scattered parts into a functional unit, and the coordination cost often eats up the few percentage points saved from piecemeal purchasing.
What Haiben does is take over this coordination process. Based on the BOM of your model or production line, we consolidate the piping modules, gather the documentation, and align the delivery schedules, delivering a kit that is ready to go directly onto your line. Clients no longer need to act as a middleman between multiple Chinese suppliers, nor do they have to deal with varying document formats during incoming inspection.
Optional Modules: Sight glasses and accumulators are provided according to customer system design specifications. They are listed separately in the quotation and are not included in the standard kit by default.
What We Proactively Do Not Do
We do not manufacture complete units, nor do we produce electrical controllers and valves requiring electrical certification, or finished line sets for after-sales installation. These categories either exceed the scope of piping components or shift compliance responsibility to a position we are not suited to take. Narrowing our boundaries ensures that the specifications and documentation of every module in the kit can be strictly controlled.
Documentation and Lead Times Are Part of the Kit
For assembly plants, the "completeness" of a kit is not just about whether all parts are present, but whether the accompanying documentation can support customs clearance and incoming inspection. We treat the copies of certificates for certified modules, material certificates, and dimensional inspection records as integral components of the kit delivery, not as attachments to be supplemented after the fact.
If your production line requires a production-ready piping kit
Tell us your model, BOM scope, and target market. We will confirm the kit composition, documentation requirements for certified modules, and delivery schedule according to your specifications. You don't need to pre-screen multiple suppliers first.
