A53 ERW STEEL PIPE

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 cutting is stamped and stretched into shape using the stamping die

The "8" character is a type of pipeline component, mainly for the convenience of maintenance. You can paint the upper half of the "8" character black to determine the specific shape. It's half a blind plate and half an iron ring. Commonly used for pipeline flanges that require process changes, the materials mainly include carbon steel, stainless steel, and alloy, which can be selected based on the pipeline pressure level and pipeline medium.

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 cannot be dismantled. The design of the pipe cap includes a convex pipe cap, a conical shell, a reducing section, a flat cover, and a tightening mouth. Convex pipe caps include: hemispherical pipe caps, elliptical pipe caps, dished pipe caps, and spherical crown pipe caps. From the perspective of force, the convex pipe cap gradually becomes less effective than the hemispherical pipe cap, but from the perspective of manufacturing difficulty, it gradually becomes easier to manufacture.

Stainless steel elbows need to be protected according to certain process measures during use and production, to protect the rationality and quality of castings. Production and processing should be carried out according to certain process techniques to protect the quality of stainless steel elbows. The stainless steel elbow is protected by a long nozzle and enters below the liquid level of the ladle. The ladle is sealed with a cover, and the sealing between the long nozzle and the ladle cover is also necessary to protect the sealing performance of the casting. Before injecting water into the stainless steel elbow ladle, the ladle is filled with argon (nitrogen) for about 6 minutes to ensure that the oxygen content inside the ladle is less than 2%. A certain amount of oxygen input is strictly controlled to ensure good performance during use. Through such protection, the oxygen content in stainless steel elbows will remain unchanged or decrease to some extent.

A pipeline silencer is a composite sound-absorbing hood with a composite structure of high temperature and high pressure steam, as well as low pressure steam, that enters the secondary pressure reducing body after a one-time expansion and pressure reduction in the silencer, and then forms low pressure or ultra-low pressure steam through a large volume expansion and pressure reduction. After being sprayed out, it is further silenced and reduced outside the pressure reducing body before being released into the atmosphere. The steam exhaust muffler of the waste heat boiler has the advantages of high safety factor, large noise reduction value, small equipment size, light weight, and easy installation.

Brief introduction of PZ43H plum blossom knife gate valve: The opening and closing part of the knife gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The wedge angle varies with valve parameters, usually 50.

The HL44X full flow anti clogging valve is designed and produced by introducing advanced foreign technology. This valve is widely applicable to the inlet end of pipelines such as water supply systems and sewage systems. Its characteristic is that the flow is large (full flow), and its structure is novel and unique. By operating the pull rod, the medium in the pipe can be emptied, greatly facilitating the maintenance and repair of pipeline facilities.
