Shandong Qinglei Environmental Science and Technology Co., Ltd.
Our custom heat exchange systems serve industrial clients across chemical, pharmaceutical, food & beverage, energy and HVAC sectors, backed by full in-house fabrication, strict quality inspection and seamless export services.
OUR CORE CAPABILITIES
Full-process In-house Design and Production
Every industrial process has different thermal requirements, operating pressures, media characteristics, and installation conditions. Qinglei provides custom heat exchanger and pressure vessel manufacturing based on customer specifications rather than limiting projects to standard catalog configurations.
Storage Tanks
Atmospheric tanks and pressure vessels made of 304, 316L, duplex 2205, 2507, carbon steel, titanium, and Hastelloy — built to drawings or process data.
Explore the range
Pressure Vessels & Reactors
Jacketed reactors and mixing tanks are fabricated to drawings or custom-designed based on operating conditions.
Explore the range
Integrated Units
Skid-mounted heat exchange units, hot water units and temperature control systems with PLC control and packaged piping.

Talk to an engineer
info@qingleikeji.com Send your specification Which design codes and standards do you comply with?
We design and fabricate to GB/T or ASME standards. Simply specify your required design code with your inquiry, and we will ensure full compliance across all calculations, material selection, and inspection planning from day one.
Can you size the equipment if we only have process data?
Yes. Send us the process data you have and our engineering desk will come back with a sizing proposal for your review.
What materials are you capable of processing?
Carbon steel, stainless steel, duplex, titanium, and Hastelloy are all expertly processed in our own workshops. Simply provide your process parameters, and we will optimize the material selection for your application.
How long is production and how do you handle inspection?
Production time is confirmed together with your quotation, and the inspection and test plan is agreed with you before fabrication begins.
Do you supply drawings and documents for approval?
Yes. Drawings and documents are issued for your review and approval before the work moves to fabrication.
What are your payment and shipping terms?
Payment is generally made via T/T or L/C. We support flexible shipping terms, including EXW, FOB, FCA, CIF, DAP, and DDP. Please let us know your preferred options with your inquiry.
