Waterproof board manufacturers: the reinforcement of geosynthetics
1. In the slope project, reinforced measures or gravel bins can be used to build steeper slopes and repair damaged slopes.
2. On the soft soil foundation, non-paved roads, road and railway subgrade works, airport roads and dams can be constructed through grassroots reinforcement measures.
3. Geotextiles or geogrids can be used to construct erected retaining walls that are upright or nearly upright.
4. In the case of fractured rock formations or the presence of small karst voids, reinforcement measures can be used to mitigate the effects of fissures and karst voids.
5. In the shallow foundation, the reinforcement of the foundation can be improved by the reinforcement of the waterproof board manufacturer's products, and the deformation characteristics of the foundation can be improved.
6. In the pile-supported reinforced embankment, several layers of reinforcement measures can improve the integrity of the whole system and improve the deformation characteristics of the embankment.
7. In the landfill cover system, the stability of the slope of the cover can be improved by the reinforcement of the cover soil layer.

Flange is an essential part of pipeline connection, according to the standard is divided into JIS BS DIN ANSI Italian standard. Flange standard is widely used, 10kgs and 16kgs, pressure carbon steel flange, is the most conventional, the most popular, and Commonly used flanges.
The biggest use of flanges is as a way to connect pipes, Valves, pumps and other equipment to form a piping system. It facilitates the cleaning, inspection and maintenance of pipes. Reduced engineering costs.
Weld the flange and the pipeline evenly, and then fasten the connection with bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the whole pipeline is integrated and starts to work normally.
It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments.
Type of flange:
According to the shape can be divided into: FF flange, RF flange, BLIND flange, SLIP-ON flange, Welding NecK
Flange, Threaded Flange, SocketWeld Flange.
According to the pressure can be divided into: PN16. PN10. PN25, PN40, PN60, PN100,
According to the process, it can be divided into: forged flange, cast flange, steel plate flange
According to the material can be divided into: carbon steel flange, stainless steel flange, alloy steel flange
Flange production process:
1) a: Forged flange
Saw billets of different specifications and models into flange blanks, add them to a reverberatory furnace and heat to 1000 degrees to take out, and then forge the flange blanks into ring flanges by forging machines such as forging presses and air hammers, b: steel plate flanges
Put the steel plate into the punching machine, put it into the corresponding mold, and directly punch it into a ring flange blank.
c: cast flange
Put the low carbon steel standard scrap into the intermediate frequency furnace and heat it to 1200-1500, pour it into the mold
The type is a ring flange blank.
2) The formed ring flange blank is processed into a ring flange on a CNC machine tool according to the drawing, and then the flange is drilled with a CNC drilling machine according to the drawing requirements, and the finished product is completed.
3) For the finished flange product, the thickness, hole diameter, center distance, inner and outer diameter of the flange shall be inspected according to the drawing requirements.
4) Type the flanges that have passed the inspection on the end face of the flange according to the customer's requirements, and do anti-rust treatment to the flange according to the customer's requirements, 1: paint, 2: anti-rust oil, 3: galvanized, and then install it. In wooden box for shipment.
