Tube Shield ET Wear Shield 316L
Tube Shield ET Wear Shield 316L - seamless steel tube
Integral cast pipe saddle clamp, special matching accessory for boiler tube erosion shields, adjustable mounting holes, high toughness anti-vibration for power station heat exchanger pipeline.
Cast pipe clamp is an integrated saddle-type cast fastener specially matched with tubes erosion shields for thermal power boiler heat exchange tubes. It adopts one-piece casting forming, with smooth inner arc closely fitting the outer wall of boiler tubes, used to lock and fix erosion shields on tube surfaces to prevent displacement under high-temperature flue gas scouring and vibration.
Both sides of the clamp are designed with long oval adjustable mounting slots, which allow horizontal fine-tuning during on-site boiler maintenance, effectively solving the installation deviation problem caused by tube layout tolerance. The body is thickened cast, with excellent toughness and vibration resistance, and will not crack or deform under long-term high-temperature working conditions of the boiler furnace.
As a complete supporting accessory of boiler tube erosion shields, it forms a set of tube anti-abrasion protection system together with erosion shield and snap ring, widely used in CFB boilers, waste heat boilers and conventional power plant economizer, superheater and reheater tubes.
| Casting Material | Core Feature | Boiler Working Condition |
|---|---|---|
| HT200 Grey Cast Iron | Cost-effective, good vibration absorption | Medium & low temperature conventional boiler tubes |
| QT450-10 Ductile Iron | High toughness, anti-crack, temperature resistant | CFB circulating fluidized bed high vibration boiler |
Selection Tip: QT450-10 ductile iron cast pipe clamp is the preferred solution for CFB boilers with severe flue vibration.
| Matched Tube Outer Diameter (mm) | Clamp Total Width (mm) | Adjustable Slot Range |

For long-term boiler operation, cast pipe clamp is more cost-effective and reduces shutdown maintenance frequency.
1. Cover the boiler tube surface with tubes erosion shield first, align the position of the protective cover.
2. Buckle the cast pipe clamp on the outside of the erosion shield, make the inner arc fully fit the shield surface.
3. Adjust horizontal position through long oval slots according to tube bundle layout, then lock high temperature bolts and washers.
4. During boiler overhaul, check clamp deformation and bolt looseness regularly, replace cracked cast clamps in time.
5. Avoid heavy hammer knocking the cast clamp during installation to prevent hidden cracks inside casting body.
1. Saddle curved surface fits erosion shield completely, no local pressure damage to protective cover and tube.
2. Extended slotted holes reserve enough tolerance for tube manufacturing & installation errors.
3. Thickened stress concentration area at both ends to resist flue gas long-term vibration fatigue.
4. No sharp corners on inner surface to avoid scratching the surface of anti-abrasion shield.

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
