QUALITY THE DAN-LOC WAY
Your operation can’t risk failures. You have to know that you’re getting quality products that live up to your performance requirements. DAN-LOC goes above and beyond to give you this level of assurance.
There are several stages that go into the manufacturing process, and DAN-LOC leaves nothing to chance with any of them, including the sourcing of our raw materials. All of our steel is made in the U.S. and comes from mills that we know and have worked with for a long time. These mills perform vacuum degassing and controlled diameter reduction to ensure quality and make the steel cleaner and stronger. Yet, even though we have immense confidence in our suppliers, we still test our incoming material, so you can have immense confidence in our products. We perform Positive Material Identification (PMI) testing to ensure we have received what was expected and that it is manufactured to specification.
From PMI testing on, we handle every step ourselves in our Houston manufacturing facility. We use rigorous process controls in our heat-treating and roll-threading methods to attain the highest level of product reliability. Then we double check our work through exhaustive laboratory analysis. We mechanically test samples from each bolt production run to validate tensile and yield strength, elongation and reduction-of-area percentages, proper Charpy impact values for low temperature applications, and thread geometric integrity.
Our ultimate goal always is to provide the highest level of quality in everything we make and everything we do. We work to exceed industry standards in our products and to exceed customer expectations in our service. While stud bolts and ring joint gaskets may seem like simple items, they are critical components to our customers operations, and they absolutely must perform. We believe one of our greatest duties is to help our customers prevent failures, thus all of our procedures are geared toward reducing their risk, and boosting their confidence.
