Safety first
Design and manufacturing decisions begin with safe, stable operation.

Industrial boiler company in China
Thermal oil heaters, industrial steam boilers, complete-system engineering and electrical controls delivered by one experienced manufacturing team.
Our company
Shandong Jieli Thermal Equipment Co., Ltd. has 30 years of professional boiler design and manufacturing experience, centered on thermal oil heaters and industrial steam boilers. Based in Luozhuang District, Linyi, Shandong, we are licensed by Chinese regulatory authorities for boiler and pressure vessel manufacturing.
We manufacture the boiler and coordinate its fuel equipment, circulation or feedwater system, heat recovery and controls. The proposal identifies the supplied equipment and its connections to the customer's plant.
Project-specific design and manufacturing can follow applicable ASME, CE (PED Directive) and other standards. Electrical control engineering is one of our strongest capabilities. We aim to make the complete plant safer, easier to operate and better coordinated, so customers can run their equipment steadily, reliably and efficiently over the long term.
Experience across industries and borders
Relentless Dedication•Advanced Reliability
Our equipment and systems serve chemical, petrochemical, food, textile printing and dyeing, plywood manufacturing, leather, building-material and other industrial processes.
JIELI THERMAL boilers have been exported to more than 30 countries and regions, including South Korea, Japan, Australia, Poland, Austria, Russia, Ukraine, Indonesia, Thailand, Malaysia, Pakistan, Argentina, Chile, Saudi Arabia, Egypt, Brazil, Nigeria, South Africa, Ethiopia, Algeria and Cambodia.
Design and manufacturing decisions begin with safe, stable operation.
The boiler, auxiliaries and controls must work as one plant.
We select capacity and auxiliaries from the fuel analysis, operating load and site conditions.
Practical operation and maintainability guide the final solution.

Manufacturing base
Our product range centers on thermal oil heaters and industrial steam boilers fired by gas, oil, biomass and coal. Explore our boiler manufacturing capability, complete boiler system supply and industrial boiler project references. Manufacturing, system engineering, controls and quality verification are coordinated around safe, stable and maintainable operation.
Explore ManufacturingMANUFACTURING & PROJECT RESPONSIBILITY
JIELI is an industrial boiler manufacturer in China focused on thermal oil heaters, industrial steam boilers and coordinated heating systems. For each project, agree on the fabrication scope, system interfaces, inspection plan and export documentation before placing an order. The proposal should clearly separate equipment supplied by JIELI from installation work and local approvals arranged by the buyer.
Compare pressure-part and coil fabrication, welding controls, inspection records, assembly capability and the agreed test plan—not only a company label.
Confirm responsibility for burners or solid-fuel equipment, pumps, tanks, feedwater, controls, heat recovery, emissions equipment and interfaces.
Define drawings, document language, packing, shipment split, local approval responsibility, installation support, commissioning and spare parts before order.
PROJECT DOCUMENTATION
Project documentation: agree the applicable design code, inspection route and required records before order. A reference to ASME or CE/PED requirements is distinct from holding a current certificate or authorization for a particular scope. Verify the issuer, legal entity, scope and validity of any required certificate.
Review the manufacturing quality-document checklist and send the required documents with your project enquiry.
