- How do you make clad?
KLAD utilizes two methods of manufacture to produce metallurgically bonded clad piping products. (See Production Techniques)
- Is clad a "liner"?
KLAD products are not characterized as a "liner". All of our products are metallurgically bonded metals that physically behave as one material.
- What sizes can KLAD produce?
Production quantities start at 4" pipe size, but we are able to manufacture smaller diameters depending on the application. There is no limitations on larger sizes.
- What cladding method is most economical?
This always depends on the size, quantity and schedule of the project. Since KLAD is able to produce clad piping with many different methods, we will offer the most economical solution.
- What is the relative cost difference between solid alloy and clad piping materials?
Its difficult to state an approximate price difference since it depends on the size and grade of cladding material. But, the price differences dramatically increase as the wall thickness increases and the higher alloy for cladding utilized.
- How are KLAD pipe and components inspected?
All KLAD pipe and components are fully inspectable with standard NDE techniques.
- In weld overlay, do I need a single layer or a double layer weld overlay?
This is, of course, your decision. Usually, a single layer overlay with an over-alloyed consumable and a low dilution process, will provide a deposit that is equal to or better than the targeted alloy chemistry. However, if the deposit has to meet the exact specification of the wrought alloy, a two layer overlay is sometimes required so as to minimize the effect of dilution and guarantee the chemistry requirement. Please refer to our Weld Overlay Capabilities Brochure.
- How thick is your cladding?
This is determined by the client. However, most applications require 3mm or .125". If you are thinking about a thicker corrosion barrier, you should consider a higher alloy instead.
- How are the longitudinal welds made for pipe and pipe fittings?
KLAD utilizes a few different methods. One method would be similar to any other longitudinal welded pipe--bevel, form and weld. Another method is more involved. The plate is edge prepped, beveled and formed. The carbon steel is welded from the outside and the cladding is restored along the weld seam via weld overlay from the inside. This is called a "backclad" weld. The method you need will depend on the conditions and temperature of your application and other design requirements.
- How are the girth welds produced?
They are similar to the longitudinal welds. Girth welds less than 24" diameter are made with a solid alloy. For diameters 24" and larger, a backclad weld can be made.
