Well Understood, Why China will fail.
Why do ANSI/SAE standards for quality make the USA the best supplier.

The Trump tariffs are not the final answer.

The quality of the product will quickly determine if China will succeed.

Demand for any product is always based on the quality, the fit in the system and the service support.

North American consumers are focused on price of the product and immediate delivery thereof.

Thus the Amazon or Walmart effect on consumer goods with a throw-away price. This is the Chinese Zone or the areas that require no support.
Price is seldom remembered when we consider it is the quality, the reliability, the service support of the product is always remembered the most.
The final thought process in purchasing any product or part of a product is simple…. How long will it last? How much will it cost to operate? How will it fit? Where will I get service and market support?
For certain any consideration to buy Chinese products has allowed your purchasing agent or you , the purchaser , a new opportunity for corner cutting and avoiding of standards of manufacturing quality.

Right down to cotton products and shoes you buy, you will discover something is not just the same as good old American standards for quality.

This is where the Chinese leaders are lost….they only consider #1. They cannot consider the needs of the North American consumer.
The Japanese caught on….and remain the great supplier of outstanding quality, product support, and superior reliability.
This is because the Japanese were able to supply products in a blend that matches the American and Japanese consumer. The number 1 consumer is the customer that writes the check in Japan which allows them to build cars in the USA with parts built in the USA.
Japan and South Korea jumped way ahead when they finally realized they had a quality problem.

The Chinese can only sell based on price.

It does not matter when the part does not fit initially.
The assembly man will chuck the part when it leaks.
Time and labor is important. Safety is compromised.
Costs of assembly and operational costs go way up.
Field service and support becomes very difficult.

The Chinese manufacturer/USA Chinese importer must develop the steady cash flow from the user or supply house.

Once the initial sale is made and parts are in the system the pandemonium begins.
The Chinese have set the hook and they rewrite the book based on their standards not ours.

Where ever you go in manufacturing this Chinese problem runs rampant.

What you perceive as a good buy is normally a loss.
The price is forgotten and the non-serviceable component is thrown away.
The part compromises safety, performance or takes too much labor to fix.

The poor quality is now remembered and the price is remembered as cheap and much more expensive than first thought

Another Chinese Problem at the consumer level. The charger decals are impossible to read….

The operating instructions are so fine that only and magnifying glass can be used.
The California hazardous chemical decal is non readable.

But MADE IN CHINA is pretty easy to read.

This part must be built and supplied to USA consumer expectations and standards.
The rules of China apply to China.
Export is only successful when the standards of the consumer or the industries are met.
A lesson learned by South Korea and Japan.
Meet or exceed the standards. Quality is critical.

Another example of Chinese Standards vs American Standards. https://en.wikipedia.org/wiki/Machinery%27s_Handbook

A commercial best seller and a lifetime friend. The Machinery’s Handbook, A rite of passage for every engineer,

What is the investment to help maintain quality?

Priced at $109 for the book written by Erik Odberg in 1914.
The special threading CNC Inserts are about $25 to $100 for Carbide,
A complete set of ring and plug gauges for 1/8 NPTF to 3 inch NPTF, $5,000.
Training of the CNC operator based on educational level.
Training of the QC department. How to accept and how to reject.
Training of the Quality People or the management of branding, product initial image and the China stamp on the part.

Note: The Machinery’s Handbook contains information based on 106 plus years of machining standards. Erik Odberg wrote the first book in 1914. The standards are established by ANSI, ASTM and ASME to confirm description, quality, reliability and high value end use or guaranteed fit of parts.

Pipe threads are built on Computer Numerical Controlled machines known for high repeatability and allowing the use of Ring Gauges and Plug Gauges to double check the workmanship.

Manufacturers that work with compressed gas and high pressures of hydraulics must spend thousands of dollars on quality control tooling to check pipe threads. We spend thousands of dollars for carbide inserts to build the threads with high repeatability.

In fact when you consider the threading of two mating surfaces with NH3 flowing inside requires the highest quality. In fact Exactrix will build the parts when the quality part cannot be purchased.

Here is what we have discovered with critical but very simple parts.

The best hydraulic fittings and pipe fittings come from Anvil and Brennan. These are the US companies that set or meet the ANSI/SAE standards for pipe fittings following the baseline Machinery’s Handbook for National Pipe Tapered Fuel threads.

National Pipe Tapered Fuel, NPTF is the standard of any plumbing parts and thread supplier involved in supplying components to petroleum, compressed gas or high pressure flows.

The Machinery’s Handbook says….for NPT (National Pipe Thread) and NPTF (National Pipe Tapered Fuel) threads. These standard threads will mate at 5 turns to “hand tight” and “full tight” is 7 turns.
NPT and NPTF are compatible with each other.
NPTF gas sealing or gas tight has truncated threads requiring a different carbide insert.

The following parts have the look of North American Brennan quality with a nice electroless nickel plating….but guess what they are rejects.

Both parts are built by the same Chinese Company and sourced from the same supplier in Spokane, Washington.

The adapter part is a 1 inch NPTF female swivel by 1 inch NPTF female mating to a 1 inch NPTF pipe hex head pipe plug.

You have seen this before but did not know what the problem was.

This 1 inch pipe thread should be hand tight at 5 turns….it is tight at 2.25 turns.
This is not a safe part and will never seal or be safe long term.
A rejected part….but sold across the board as meeting SAE and ANSI standards.

So is the USA getting the rejected parts while China gets the good parts?

Our USA importer is not wise or is considered just as responsible as the Chinese for dumping defective product into the USA.
The problem of quality is just as much our USA importers that promote the part as meeting the standards.
It is China that is the real problem because the importer is forced to take the rejects. The parts must be rejected in China, not in a Los Angles warehouse.
Once again beware China is growing and failing at the same time.

For sure these Chinese parts do not meet ANSI/SAE standards.

The ability to build the part is not questioned. The finished part is a reject based on the common information found in the Machinery’s Handbook. The solution comes right down to the man in charge of CNC machining center that builds the part. The problem is the management in China and the USA Importer that will accept rejects.

People that do not have a need for quality should buy these products and build infrastructure around the Chinese reject….not following standards is a nightmare for any country that wants long term service with safety.

The facts move around everywhere in the supply chain, stainless quarter turn ball valves, rated 1000 psi, that leak at 150 psi from the factory.

Importers, manufacturers must get the word back to China, “Send only your best and you keep the rest.”

Critical to any manufacturing operation is the measurement tools that accept or reject the part right at the CNC machine tool with random sampling.

Ring Gauges, Plug Gauges that are part of the cost of doing business, the quality control program.

You must have a calibrated measurement means to make the correction to meet the standards.

China, “Send only your best and you keep the rest.”
