Standard Angle, Reliable Seal
The 90-Degree Elbow Emergency Repair Clamp is our standard product for 90° elbow leaks. This is the most common elbow angle in pipe networks. We have made many of these clamps. Our design is proven and reliable. You get fast delivery because we have molds for standard sizes.
The housing matches the standard 90° elbow geometry precisely. Two halves join to form the complete elbow enclosure. The gasket has three sealing zones. One zone seals the inlet socket. One zone seals the outlet socket. One zone seals the bend area. All three zones are connected. This gives continuous sealing around the entire elbow. Eight or more bolts provide even compression. The clamp holds against water pressure and vibration.
We hold ISO 9001 and ISO 14001 certifications. Our products are tested by the Shanghai Institute of Quality Inspection. We test every clamp at 2.4 MPa before shipping. We have standard molds for DN40 to DN300 90° elbows. Custom sizes and angles are available on request. We can work from your sample or drawing.
Used in an Oil Field Fire Network
An oil field in the northwest had a DN150 90° elbow leak. The fire network could not be shut down. Winter temperatures reach -20°C. The team used our 90-Degree Elbow Emergency Repair Clamp. They installed it under pressure in freezing conditions. The clamp has been in service for three years. It survived both winter cold and summer heat. The seal is still perfect.
We offer a 10-year warranty. The housing is QT450 ductile iron with epoxy coating. The gasket is EPDM rubber. Standard 90° sizes ship quickly.
