Malleable Iron SCC Short Compression Coupling NPT Thread

Products Details

Malleable Iron SCC Short Compression Coupling. SCC short comoression coupling has the same function with LCC. The term “short” implies that the coupling has a compact or abbreviated design compared to longer versions. Compression couplings, in general, are known for their ease of installation and ability to create a secure, leak-free connection.

Product Drawing

Production process -10：Threading

The casting before the threading process is called a blank. Some customers, due to the requirements of their country or region, also purchase blanks directly from our company, and perform wire-laying processing in their country according to the requirements, so as to comply with some special use requirements of their country or to comply with the requirements of the country of origin, thereby reasonably avoiding some taxes. .
Threading refers to machining the blank parts to produce threads of different national standards on the castings according to the customer’s requirements.

Our advantage of threading

1. We can make both of NPT and BSPT thread. NPT as per ANSI/ASTM B1.20.1 and BSPT as per ISO 7-1 or BS21.

2. In order to ensure the actual use effect of the pipe fittings and ensure that the pipe threads can match smoothly, our pipe fittings are designed to ensure the use space of the inner cavity as much as possible, and the thread tail is designed as an empty knife structure, so that the internal threads are completely tapered, ensuring the use effect .

3. In order to ensure the accuracy of the base surface position, we always control the base surface of the tapered pipe thread at the best position during processing. The base size of the branch pipe fittings, that is, the thread accuracy, is higher than the national standard. The national standard stipulates ±1 1/4 buckles, and our pipe fittings are stipulated and guaranteed to be within ±1 buckle.
