Hydraulic support pipes are made of high-quality carbon structural steel with appropriate addition of one or several alloy elements to improve the strength, toughness, and hardenability of the steel. After being made, this type of steel usually needs to undergo heat treatment such as quenching and tempering, chemical heat treatment, and surface que1
Equal diameter cross, commonly referred to as a professional term, refers to pipe fittings and pipeline connectors, used in main pipelines where branch pipes are required. Equal diameter cross is a type of cross, which can be divided into two types: general equal diameter cross and differential diameter cross. Named because the four ends can be con1
ASTM A252 Standard is Specification for Welded and Seamless Steel Pipe Piles EN10219 / EN10210 S275J0H S355J0H ASTM/ASME A252/SA252 steel piling pipe is a structural pipe ideally suited for application in buildings, retaining walls, and other structures needing solid, dependably, quality made steel piling pipe as its structure.
In addition to using steel pipes as raw materials to produce eccentric reducing pipes, some specifications of reducing pipes can also be produced using stamping forming technology using steel plates. The shape of the stamping die used for stretching refers to the design of the inner surface size of the reducing pipe, and the steel plate after cutti1
Pipe cap, also known as head, plug, cap, pipe cap, or blind, is a pipe fitting welded to the pipe end or installed on the external thread of the pipe end to cover the pipe. Used to close pipelines, with the same effect as pipe plugs. The form of blind plates is similar, except that blind plates can be dismantled for sealing, while welded pipe caps 1
Bend pipes are bent using a complete set of bending molds, which are divided into two processes: cold bending and hot pushing. Regardless of the type of machine equipment and pipeline, most of them use bent pipes, mainly for oil, gas, infusion, and other purposes. Classification: According to the production method, it can be divided into pushing, p1
Signal butterfly valves are suitable for pipelines in systems such as petroleum, chemical, food, pharmaceutical, papermaking, hydropower, shipbuilding, water supply and drainage, smelting, energy, etc. It can be used as a regulating and throttling device on various corrosive, non corrosive gas, liquid, semi fluid, and solid powder pipelines and con1
This valve is a type of valve with a DC body structure and special digital locking function. It has better equal percentage flow characteristics and can reasonably allocate flow, effectively solving the problem of uneven room temperature cooling and heating in heating (air conditioning) systems. The valve is equipped with an opening indicator, an o1
