Why a CNG skid needs two special-equipment licences
High-pressure gas equipment is not something anyone can build. A manufacturing licence and an installation licence decide who is able to sign the contract.
A CNG pressure-reducing skid is high-pressure special equipment, and the manufacturer must hold the corresponding qualifications. Hebei Tairan holds both the special-equipment manufacturing licence and the installation licence issued by the State Administration for Market Regulation.
Special equipment manufacturing licence (No. TS2713287-2027) covers pressure piping components, including gas regulating assemblies and component combination assemblies, with design pressure up to 27.5 MPa — enough for CNG reducing skids. The renewal audit examined the production site, machining equipment, inspection means and the quality assurance system in full.
Special equipment installation licence (No. TS3813652-2027) covers Class GC2 industrial piping installation. Holding both means a client deals with one company from equipment manufacture through site installation, with responsibility clearly divided.
Beyond licensing, the company has been rated Grade A in tax credit continuously since 2019, holds a AAA enterprise credit certification from a third-party agency, and has no administrative penalties, abnormal-operation listings or serious dishonesty records in the national enterprise credit information system.
On the product side, the CNG reducing skid's three-stage reduction and dual-line automatic changeover earned the Gas Regulating Equipment Technology Innovation Gold Award in the 2025 industry evaluation; customer satisfaction in the same year's survey was 93 %; and the product was listed among the 2026 Recommended Gas Equipment Brands.
