Material Composition

The product is made of high-quality materials, which are all non-toxic and safe to use. The length and thickness of tubing can be customized, according to the client’s demand. A variety of dyes are available for selection. Most tubes are semi-finished products that require minimal processing before being sold as finished goods. Also, most tubes have a standard outside diameter, wall thickness, inside diameter, etc., so customers don’t need to worry about these parameters during production.

Processing Procedure

The U tube manufacturing process begins with cutting a circular strip of metal. The size and shape of these tubes vary according to requirements, and then they are welded together in series. The centre hole is made after welding and openings at both ends. These openings help in fastening nuts at one end, while allowing unidirectional water to flow through them. After these steps are completed, U tubes can be produced as per requirements by machining or casting them.

Quality Control Procedure

There are three important stages in the U tubes manufacturing process. The first is that we buy raw materials from different suppliers and check them before processing U tubes. These materials are quality verified by our expert team on different parameters to provide the best products to our clients at a reasonable price. The materials supplied to us should be free from defects and provide a smooth finish for welding purposes. The material which does not meet these standards is rejected before further processing.

Finishing quality of Krystal Global Engineering Limited


The finishing process is one where we carefully inspect our products. Since each batch of materials is a little different, we want to ensure that our tolerances are correct and that no defects or debris make it through to our customers. After a lot of tests and time spent refining these processes, we have determined what works best for us and have set up state-of-the-art machines to automatically do much of our finishing work.


The first step in the manufacturing process is inspection. In order to make sure that you get only top quality products from us, we subject all our raw materials to proper and timely inspections. The first inspection is done when we accept our material from our vendors. We make sure that there are no defectives and if any, then we take them back for replacement and get replacements. Our experts keep a check on colours and finishing of raw materials so that you do not face any problems later in the assembly process or after-sale services.
