Shanghai 2012 Edition “Measurement Rules for Membrane Gas Meters”

A few days ago, Shanghai Metrology Association's professional committees for water meter, electric energy meter, and gas meter organized the "Jetification Regulations for Membrane Gas Meters" (JJG577-2012) Xuan Guan, Shanghai Gas Meter Inspection Station, and Shibei, Dazhong, Pudong, and Fengxian. A total of more than 70 representatives of gas sales companies attended the training.

In the training class, the senior engineer Chen Chao of the Traffic Measurement Research Institute of the Shanghai Metrology and Measurement Research Institute explained the contents of the procedures in detail and reminded the examiners of important issues that should be taken into account when implementing the new procedure requirements: such as adding and revising The verification projects, more scientific and accurate verification methods, etc., to ensure the quality of the gas meter verification.

Yang Lianqing, deputy director of the three-formation committee, attended the training, and he hoped that the mandatory mandatory gas meter station would strictly follow the requirements of the new regulations to carry out compulsory verification of gas meters to ensure accurate and reliable metering of gas meters; Control the production process and control the quality of the manufactured products to ensure that the performance of the gas meters is safe and stable; each gas sales company properly selects and uses gas meters; ensures the fair and just measurement of gas trade, and creates a harmonious, stable and accurate city. Gas trade legal system measures new environment.

Precast Concrete Magnet

Precast concrete magnet is configured with a big neodymium block magnet in to a steel house.the neodymium block magnet is very big of size which is very large.Magnet for precast concrete, is a magnetic tool to hold concrete formwork. There are two hex bolt and a round handle button on the top of the precast concrete magnet, the hex bolt is for fixed with adapter and handle button is for push to use.

How to use precast magnet box? People who use this magnet need to find some shuttering adapter to suit the precast magnet box onto the concrete framework, this framework could be made of plywood,wood, iron steel, aluminum... Then push the round handle button on the top, the block magnet in steel box will sink and contact and catch with iron steel part. After setting the magnet to the formwork,The concrete will be formed trimly just as the precast framework likes.

If someone want to remove the concrete magnet, he need to find a crowbar and pry up the round handle button and the block magnet will return to its position and not catch the iron steel.

Using the concrete formwork magnet is very convenient, construction workers could build a concrete formwork on a ground ,and fit two hex bolt with the adapter onto the the concrete formwork. There is another means of using the concrete formwork magnet,workers could hold the concrete formwork on a hydraulic platform,build and stock the concrete walls,and using forklift and crane to carry the walls while using them.

What are the advantages of using precast concrete magnet in modern architecture construction? By using the concrete magnet, the concrete could form very trimly of sizes for building constructions. By using the concrete magnet, the construction process could be much quicker as workers could stock concrete walls and use these concrete walls to build architecture. The repute of the construction company will be much better and customer will happy to pay the money for the timely construction works. By using the magnet for precast concrete, there will be less concrete works in dangerous high situations, worker could finish their work more safely and construction could save more insurance cost and give higher salary to the workers.

By using concrete formwork magnet,the workers could save more time while build constructions, after using concrete formwork magnet, there will be less risk or danger during the constructing process. In a word, the concrete formwork magnet could enhance the speed of build while inform more security,the workers could make more money from the construction and businessman could earn more money from their business.

The concrete formwork magnet is strong magnetism,please keep the electrical product and card away from it,also, while using the concrete formwork magnet do not put your hand or feet or any part of body under the magnet,it will cause injure.
