Basic introduction to national standard flange

Flange joint is a component that is very commonly used in engineering design and covers a wide range of areas. It is an indispensable part in piping design, pipe fittings and valves, and is also an essential component in equipment and equipment parts (such as manholes, sight glass level gauges, etc.). In addition, other majors such as industrial furnaces, thermal engineering, water supply and drainage, heating and ventilation, automatic control, etc. also often use flange joints.

Identification of national standard flange materials

Stainless steel flange, also called flange plate or flange plate, is a component that connects pipe ends and valves to each other. The stainless steel flange connects the pipe ends on both sides. The flange itself has holes.

National standard flange level and its requirements

Butt welding flange is a type of pipe fitting, which refers to a flange with a neck and a round pipe transition and is butt welded to the pipe. The butt welding flange is not easy to deform, has good sealing, and is widely used.

Characteristics of ring mold

Ring die materials and heat treatment ring die materials mainly include carbon structural steel, alloy structural steel and stainless steel. The heat treatment hardness of carbon structural steel such as 45 steel is generally HRC45~50.

Ring mode pellet machine

Powdered feed and grass meal can be granulated without adding a little liquid, so the moisture content of the pellet feed is basically the moisture content of the material before granulation, which is more convenient for storage.

The difference between ring die pellet machine and flat die pellet machine

The ring die pellet mill adopts mechanical forced feeding, high-speed rotation and centrifugal distribution into the granulation chamber, and the material is distributed through a scraper, so the feeding is uneven; the flat die pellet mill uses the material's own weight to enter the pressing chamber vertically and can feed the material evenly.

Congratulations to Jinan Hongtu forging Co., Ltd. for launching its website

It is located in Zhangqiu, Shandong Province, the "hometown of blacksmiths". There are National Highway 309 (via Shidong Road) in the south, G20 (Qingyin Expressway) in the north, and Line S102 (Ji-Qing Expressway) in the north, with convenient transportation and smooth communication; the factory area is 11000 square meters, with 6 engineers, 10 technicians, 110 employees and 12 million yuan in fixed assets.

Flange connection

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which are also flange connections.

my country’s first set of “Pipeline Integrity Management Specifications” was released in 2017

On February 19, 2017, the reporter learned from the pipeline company that after more than four years of research and practice, the "Pipeline Integrity Management Specification" was approved by the group company and became my country's first independently developed and compiled pipeline integrity management enterprise standard.

Flange introduction

Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, then add flange pads between the two flange plates, and then use bolts to tighten the two flange plates. It is tightly coupled with a detachable joint. Flange connection is an important connection method in pipeline construction.
