ZHEJIANG QISHENG · FLOW-PATH PARTS, REVERSE ENGINEERING & MAINTENANCE
Carbon rings, brush seals & bearing isolators
Carbon rings, brush seals and bearing isolators shown in Qisheng's steam turbine brochure, with oil and steam seals also listed in its component supply scope.
PRODUCT OVERVIEW
Sealing components.
Qisheng's illustrated parts page shows carbon rings, a brush seal and a bearing isolator. Its business overview also includes oil and steam seals within the turbine component supply scope.
Identify the seal's location and the existing unit before comparing a replacement. Provide the available drawing, shaft and housing interfaces, operating conditions and any documented material or inspection requirements.
Flow-path components, reverse engineering and maintenance within the brochure scope are arranged by Zhejiang Qisheng Machinery Equipment Co., Ltd. CHENDA INDUSTRIAL handles enquiries, quotation coordination and contracts.

The listed sealing components relate to industrial steam turbines; no compressor spare-part scope is inferred.
Dimensions, material specifications and operating limits require component-specific manufacturer review.
State whether the enquiry concerns individual rings or a seal assembly; the supply boundary requires confirmation.

Questions about this series.
Is the bearing isolator a bearing?
It is shown as a separate component labelled 'Bearing Isolator'. Keep it distinct from the bearings and bearing housings listed elsewhere in the brochure.
Can carbon rings and brush seals be substituted directly?
No direct substitution is established by the brochure. The manufacturer needs to review the original arrangement, interfaces and operating conditions for the specific turbine.
Does the brochure state seal dimensions or leakage performance?
Pages 5 and 7 name and illustrate the components but do not provide dimensional ranges, material grades or leakage guarantees. These requirements should be stated in the enquiry.
