苹果彩票:当地人常说,腐败已经成为制度性和结构性的“顽疾”——小到在开车违章时给交警塞钱以逃避处罚,大到权钱交易,就连移民局办公大厅的宣传标语都是“除了(说)‘谢谢’,不要给公职人员其他任何形式的馈赠”。

Flange protective sleeve is a kind of protection flange, flange after installation, if the connection of the pipe flange connection or need some items not installed flange will appear a lot of problems, if the flange installed, no cases on the above set of flange, flange will be used by external factors such as friction, will cause the damage of the flange, affect the life, let's me say flange manufacturer if there is no set installed air leakage to do.

Common causes of flanges leakage

The flange face is too dirty or damaged. Gasket set of dirt, scratches, bruises and bumps on the surface of the seat, welding slag, and curved surface of socket will provide leakage paths, or lead to uneven gasket compression, resulting in leakage of flange, this is not the result of the flange cover on the installation.

The stress of bolts is not uniform. Improper fastening/assembly procedures or difficulty in contacting fasteners may loosen some bolts while excessive tightening of others may lead to washers breaking. This can lead to leakage during operation, especially when the heavy load bolts are loose during high temperature operation.

Improper alignment of the flange, especially the flange surface is not parallel, resulting in uneven gasket compression and local crushing, resulting in subsequent leakage. Improper alignment of flange centerline can also lead to uneven gasket compression and flange leakage.

The piping system at the flange position is overloaded. Excessive force and bending can result in loose bolts or distorted flanges, resulting in leakage.

Above is flange leak reason, it is enough to illustrates the important role of flange confinement, it can be very good avoid flange when connected to some of the leak cause harm to human body, such as protective role, so remember when installation of flange must be installed on the flange.
