Procurement Questions
TBM and MTBM Launch Seal FAQ
A launch seal is a circular rubber sealing component installed around the opening where a tunnel boring machine enters or exits a shaft. It helps close the gap around the shield and control soil, water, or slurry ingress during launch and reception operations.
AngXin supplies TBM and MTBM launch seal rubber gaskets, rubber segments, black eye seal components, and custom-diameter sealing parts. The featured model is an NBR joint-free rubber sheet with two internal wire layers.
Yes. The featured TBM rubber seal can be reviewed for custom inner and outer diameters. Buyers should provide the machine model, interface drawing, required dimensions, and installation details before production is confirmed.
The featured model uses NBR. Final material selection should be based on the operating medium, pressure, temperature, abrasion exposure, required flexibility, and project specification. Confirm the material with the technical team before ordering.
The published product information references AVN1400 through AVN2200 models. Compatibility must still be confirmed against the exact machine, shield diameter, interface geometry, and buyer-approved drawing.
Provide the TBM or MTBM model, inner and outer diameter, profile or thickness, reinforcement requirements, operating medium and pressure, drawing or sample photo, quantity, destination country, and requested delivery date.
Packing should be planned according to the seal diameter, weight, reinforcement, transport method, and destination. Ask the sales team to confirm the proposed packing method and handling instructions with the quotation.
Request a TBM Seal Technical Review
Send your drawing, dimensions, machine model, operating conditions, quantity, and destination so AngXin can review the correct launch seal configuration.
