This client is from Mali in Africa, he majors in the gold mining, so he needed us to offer the actual picture of the material he need when quote, we tried to find a exact same one in material and size dimension and sent the picture to him. Also depend on the light weight of this order, we suggested the customer to do DDU delivery and include the cost in the offer. He approved the order to manufacture in 3 days very shortly.

MSS SP-97:
This refers to a standard published by the Manufacturers Standardization Society (MSS).
It covers branch connection fittings, specifying their dimensions, tolerances, pressure ratings, and material requirements.
Essentially, it sets the guidelines for how these fittings are made and used.
Threadolet:
This is a type of branch connection fitting.
Specifically, a threadolet is designed to create a threaded connection from a larger pipe to a smaller pipe.
This allows for a threaded pipe to be attached to the main pipe.
An MSS SP-97 Threadolet is a threaded branch connection fitting that adheres to the standards set forth by MSS SP-97.These fittings are used in piping systems to create threaded branch connections.It is important to understand that MSS SP-97 covers multiple types of branch connection fittings, of which the Threadolet is only one type. Other types include Weldolets, and Sockolets.

How to inspect Threadolets ？
Inspecting MSS SP-97 Threadolets involves a combination of visual checks, dimensional verification, and material confirmation. Here's a general approach:
Visual Inspection:
Inspect for any surface defects, such as cracks, gouges, porosity, or laminations.
Pay close attention to the threaded areas and the transition zones.
Dimensional Inspection:
Verify the dimensions of the threadolet against the requirements of MSS SP-97 and the applicable piping specifications.
Check the overall size, thread dimensions, and wall thickness.
Use thread gauges to verify the accuracy of the threads.
Verify the wall thickness of the fitting.
