What's the difference between API6A and API 6D valves

 

API 6D and API 6A are both used as standards for valves in the oil and gas sector.

API 6D is the standard for valves in pipelines, such as in rigs, platforms, skids and production plants.

API 6A is the specification for valves used in wellhead equipment and Christmas tree accessories.

In terms of usage, there are many more pipeline valves used as compared to wellhead valves.

When it comes to ease of manufacture, pipeline valves are more easily manufactured as comparedto wellhead valves.

As for pressure rating, the most common rating for API 6D valves are from 150LB to 2500LB.

And API 6A valves are pressure rated for 2000LB up to 20000LB,i.e.2000LB, 3000LB, 5000LB, 10000LB, 15000LB, and 20000LB.

Generally, the pressure rating for API 6A valves is higher than API 6D valves, after all, they are usually used in harsher working conditions.

Copper rod machine melting,Copper rod upcasting machine,Copper plating line

China is short of copper, and China is also a big copper user. At present, the copper consumption of China's cable industry is about 7.5 million tons, accounting for more than 60% of China's total copper consumption, accounting for about 1 percent of the world's total copper conductor consumption, making it the largest copper user in the world. In order to solve the serious situation, the smart Chinese people try to use the machine which could meet the energy-saving requirement to produce the cooper rod. D&S copper rod making machine adopts the advanced fire refining technology to produce the￠8MM bright low-oxygen copper rod which is meet the international standards in the continuous casting line. The features of the production line are continuous casting and rolling process. There is no interruption from melting of raw material, casting process, rolling process and delivery of product, and it has high efficiency due to automatic control throughout the entire process. ...

Chiller installation technology

1. When selecting the position of the lifting point, first consider the best position of the air circulation, and secondly consider the direction of the structure of the storage body. 2. The gap between the chiller and the slab should be greater than the thickness of the chiller . 3. All the slings of the chiller should be tightened, and the bolts and slings should be perforated with sealant to prevent cold bridge and air leakage. 4. When the ceiling fan is too heavy, use the No. 4 or No. 5 angle iron as the lintel. The lintel should span across the other roof and wall panels to reduce the load.
