Engineering & Manufacturing.  At the heart of Bangdong`s success is technical expertise. Proprietary equipment, designed and built in-house, allows us to go beyond ordinary products and deliver superior, value-engineered products. Our skilled engineers are ready to assist you in designing metal expansion joints for the most demanding applications.

Quality Assurance.  Delivering the highest quality products is a guiding principle at Bangdong. Designs conform to EJMA and ASME Section VIII, meeting the requirements of the piping, boiler and pressure codes – B31.1 and B31.3. This certification applies to the scope of activity related to the fabrication and assembly of pressure piping, which means our engineering and production teams can design systems in accordance with the rules of the ASME Boiler and Pressure Vessel Code. This certification gives Bangdong the [U", [PP" and [R" Stamps for expansion joints. Customer specifications can be verified through Finite Element Analysis (FEA), or 3D CAD modeling. Expansion joint test options include pneumatic, hydrostatic, high-pressure gas, or liquid penetrant methods, as well as helium mass spectrometry and radiography.

Product & Failure Analysis.  A key to permanently solving any tough metal expansion joint application is to accurately identify the root cause(s) of past failure modes of products removed from service. Bangdong`s in-house product and failure analysis lab can identify various failure modes, whether a result of fatigue, corrosion, deformation, or from a host of other possible causes. Bangdong is the only metal hose and expansion joint manufacturer in North America that offers in-house failure analyses and reverse engineering as a no-charge service to its distributor partners.

Service.  With 90+ ASME IX Certified welders and a comprehensive material stocking program, Bangdong provides the exceptional service our industry demands. In addition to providing the best standard delivery lead-time, Bangdong offers our After Hours Emergency Service for hose and expansion joints, providing customers an expedited response for critical and time-sensitive situations that arise beyond normal business hours.
