Black pipe couplings are forged from high-quality black carbon steel pipes sandblasted or coated to enhance corrosion resistance. Hebei Sanvo is a quality carbon steel coupling manufacturer and supplier in China and exports and customizes black steel merchant couplings and API line pipe couplings, etc. The specifications include full coupling, half coupling, extra heavy full coupling, extra heavy half coupling, etc.
This guide answers all the questions you have about black pipe couplings. If you have been looking for information about black steel merchant couplings, look no further.
You will find the most direct, yet detailed answers to basic questions, you often ask about black steel full merchant couplings and half merchant couplings.
Without further ado, here we go:
The black pipe couplings are made of ungalvanized carbon steel pipes, which are a type of pipe fittings used to extend the pipe. Since it has a dark color surface that is formed by iron oxide during the manufacturing process, it is called a black steel pipe coupling.
And in order to enhance the corrosion resistance, the SANVO factory located in China will sandblast or oil the raw materials. The black steel pipe couplings connect to black iron and black steel pipes used to transport gas and water.
There are so many different types of couplings available and each one has its own specific application. For example, when connecting drop pipes in a well, you may consider using merchant couplings to connect them together.
SANVO black merchant couplings are threaded and made of ungalvanized carbon steel pipes, including standard black full merchant couplings, standard black half merchant couplings, extra heavy black full merchant couplings, extra heavy black half merchant couplings, etc.
Merchant couplings are manufactured per ASTM A865 and are intended for use on steel pipe joints in accordance with ANSI B1.20.1. Sizes 1⁄8" NPS through 2" NPS are straight-tapped. Sizes 2 1⁄2" NPS and larger are always taper-tapped.
All merchant couplings are chamfered before they are threaded. This means that before the threading is done, a chamfer is created. It can be tricky to tell where the threads start on the chamfer, but it helps start threading the pipe into the coupling.
SANVO is a good stainless and carbon steel coupling manufacturer, supplier, wholesaler, exporter, factory, and company in China, and supplies standard and extra heavy black steel full merchant couplings, half merchant coupling, and API line pipe couplings, etc.
And our black steel merchant couplings can be customized according to drawings, samples, or special requirements of customers and send samples for free. So, you can choose Hebei Sanvo Pipes And Fittings Co., Ltd. to buy/purchase black steel merchant couplings.
