Typically the pipe wall thickness is the controlled variable, and the Inside Diameter (I.D.) is allowed to vary. The pipe wall thickness has a variance of approximately 12.5 percent. There are two common methods for designating pipe outside diameter . The North American method is called NPS (“Nominal Pipe Size”) and is based on inches (also frequently referred to as NB (“Nominal Bore”)).
Thinking about a smoking pipe, but don’t know which shape is right for you? Tempered glass are used for specialized applications, such as corrosive liquids, medical or laboratory wastes, or pharmaceutical manufacturing. Connections are generally made using specialized gasket or O-ring fittings. The inside of pipes can be cleaned with a tube cleaning process, if they are contaminated with debris or fouling.
When the alloys for piping are forged, metallurgical tests are performed to determine material composition by % of each chemical element in the piping, and the results are recorded in a Material Test Report . These tests can be used to prove that the alloy conforms to various specifications (e.g. 316 SS). The tests are stamped by the mill’s QA/QC department and can be used to trace the material back to the mill by future users, such as piping and fitting manufacturers. Maintaining the traceability between the alloy material and associated MTR is an important quality assurance issue. Precautions must also be taken to prevent the introduction of counterfeit materials.
If the Internet hadn’t happened, we would still be in a world dominated by pipes. The Internet, being a participatory network, is a platform itself and allows any business, building on top of it, to leverage these platform properties. This formula works extremely well for ecommerce shops or subscription plays.
On platforms,more of a systems view is neededto balance out subsidies and prices, and determine the traction needed on either side for the business model to work. On a platform business, monetization isn’t quite as straightforward. When producers and consumers transact (e.g. AirBnB, SitterCity, Etsy), one or both sides pays the platform a transaction cut. When producers create content to engage consumers , the platform may monetize consumer attention .
