What makes the HSD testing more accurate and reliable than any other option on the market?
The HSD is the only field instrument that performs frictional sliding to imprint multiple long shallow grooves on the pipe surface, which enables the collection of hundreds of measurements from a single test to sample a greater volume of material and provide reliable averages.
What type of seam welds can HSD identify?
HSD Testing is calibrated to differentiate between High-Frequency, Low-Frequency, and Post-Weld Heat Treated ERW seams. This determination can significantly impact the safe operating conditions of assets by providing material properties above the conservative minimum values.
What are the procedures and specifications for testing elbows, tees and other complex geometries?
If there is sufficient area to mount the tester to the sample, the HSD can gather the necessary information. For straight joints, tee joints, and reducers, this requires a segment with at least 3” OD and 12” of unobstructed straight pipe. For most elbows, the OD needs to be 8” or greater.
Why should I account for UTS when determining grade?
API has minimum values for both Yield and UTS. It is important to confirm that samples meet API standards across all parameters to ensure safe operation.
Does the HSD work in inclement weather and abnormal conditions, such as cold weather or condensation on the pipe?
The HSD is a weather-resistant instrument that can withstand weather conditions and abnormal considerations that are safe for testing.
