Chengxin Industrial Sealing King | Industrial Sealing Solutions
Industrial Seal Failure?
Finding Practical Solutions to Problems
Please send Chengxin the location of the leak, the old parts, photos, or drawings. We will help assess the operating conditions, identify possible causes, and then evaluate the materials, structure, manufacturing process, and delivery method.
It's okay if you don't know the product name or the full specifications—just start by describing the problem you're currently experiencing.
COMMON SEALING PROBLEMS
What kind of problem are you facing right now?
First, identify the failure symptoms, then investigate the causes by examining the materials, structure, dimensions, and operating conditions to avoid replacing the same part only to have the problem recur.
Recurring leaks from flanges or equipment
After replacing the gasket or seal, the leak reoccurred shortly thereafter.
Seal wear and deformation
Unstable service life, abnormal dimensions, or signs of crushing or damage upon removal.
Material and medium incompatibility
Swelling, hardening, brittle cracking, or corrosion occurs upon contact with the fluid.
Special operating conditions or difficult-to-handle dimensions
High-temperature, high-pressure, vacuum, or corrosive environments, or situations where standard products cannot be used.
The image illustrates a scenario involving the verification of joint locations, equipment, and dimensions; actual anomalies will be determined based on on-site conditions.
HOW WE SUPPORT
Chengxin doesn't just ship products according to specifications.
We will first assess the equipment, medium, temperature, pressure, and failure conditions, and then help you compare materials, sealing configurations, and manufacturing methods. Even if your requirements are not yet fully defined, we can still discuss them.
FROM PROBLEM TO DELIVERY
A Four-Step Process from Problem to Delivery
You don’t need to prepare a complete set of specifications in advance. Chengxin will help you clarify the next steps based on the completeness of the information you provide.
01Submit a question or photo
Please provide the location of the failure, the old part, photos, drawings, or a description of the current problem.
02Organizing Operating Conditions and Dimensions
Confirm the medium, temperature, pressure, motion type, dimensions, and expected quantity.
03Verification of Materials and Structures
Compare candidate materials, sealing configurations, and manufacturability.
04Prototyping and Delivery Evaluation
Confirm the procedures for prototyping, inspection, and mass production, as well as the estimated timeline, based on the plan.
Even if the data isn't complete yet, you can still send it over.
Please provide on-site photos, old parts, drawings, or a description of the problem. Chengxin will first assess the equipment’s operating condition and review the available information, then list the dimensions and operating conditions that need to be provided.
SEALING APPLICATIONS
Sealing Needs We Can Help With
Determine the materials and structure based on actual operating conditions; don’t let product names limit your options.
Sealing of Static Flanges and Valves
Evaluate gaskets, O-rings, and custom sealing designs for flange faces, valve connections, and static joint locations.
Reciprocating and Rotating Seals
Evaluate the sealing lip, support ring, and related structures based on speed, pressure, lubrication, and wear conditions.
High-Temperature, High-Pressure, and Corrosive Operating Conditions
Compile data on media, temperature, pressure, and cleaning conditions to facilitate comparisons among engineering plastics, elastomers, and composite structures.
Special Sizes and Custom Parts
Based on drawings, dimensions, samples, or existing parts, we can evaluate the manufacturing methods, materials, quantities, and delivery terms.

FREQUENTLY ASKED QUESTIONS
Before you start asking questions, you might want to know
Even if your information is incomplete, feel free to contact us—we’ll help you figure out what’s missing.
I'm not sure about the material or specifications. Can I ask you about them?
Sure. Please start by providing the location of use, the medium, temperature, pressure, photos, or details of the current issue, and Chengxun will help you determine the next steps.
Can you provide an estimate based only on photos or old items?
This can serve as a preliminary basis for confirmation. We will provide further details regarding whether dimensions, drawings, or other information will be required later, depending on the actual circumstances.
Can you produce small-batch samples or items in custom sizes?
We can evaluate this based on the material, dimensions, processing method, and quantity. Please first provide the intended use and your requirements so we can determine the feasible options.
How are delivery dates and inspection documents confirmed?
Delivery times and available documentation will be determined based on the materials, dimensions, quantity, and order terms. We will clearly explain the feasible options before providing a quote.
TELL US ABOUT YOUR CHALLENGE
Please let us know about the issue you're currently experiencing.
You don’t need to have all the specifications ready first. A photo, a used part, a drawing, or a brief description of the problem can all serve as a starting point.
