Tube Sheet

Heat Exchanger Tube Sheet, Fixed Tubesheet, Floating Tube sheet

The tube sheets used in heat exchangers and boilers are often clad with an insulating layer which also serves to protect against corrosion.

We can produce products DN15-5000 diameter tube sheet with GB standard, American Standard, the Japanese standard, European standard and non-standard flange. Products are widely used in petrochemical engineering, food, metallurgy, construction, electric power and other machinery. Product quality and yield have been a qualitative leap.

Tube plate is in a circular plate on the drill pipe diameter is slightly larger than the same hole, pipe penetration welded fixed, plays a role of such accessories.

In the calculation of fixed tube plate in various working temperature to calculate casing axial stress, axial stress, heat pipe between the heat pipe and pipe plate pull-out force Q, one can not meet the strength (or stable) conditions, will need to set expansion joint. In the fixed tube plate strength calculation, when the tube plate thickness is determined, no expansion joint, sometimes tube plate set expansion joint, strength is not enough, the tube plate thickness could meet the requirements. At this point, it can also be set up to reduce the expansion section of thin tube plate, but from the material consumption, manufacturing, safety and economic results and other comprehensive evaluation.

Buffle Plate

Heat Exhcnager Baffles, Baffle

Heat Exhcnager Baffles are plates used to change the direction of fluid flow. They are commonly used in shell-and-tube heat exchangers to design shell-side media flow paths.

Heat Exhcnager Baffles are plates used to change the direction of fluid flow. They are commonly used in shell-and-tube heat exchangers to design shell-side media flow paths. The number of baffles is determined by the nature and flow of the media and the size of the heat exchanger. The baffle is placed in the shell side, which improves heat transfer and supports the tube bundle. The baffle has two kinds of bows and discs-circular rings. The bow baffles have three kinds of bows, double bows and three bows.

Expantion Joints

Caps

Wall thickness for caps up to and including 36″ conform to ANSI B36.10 specifications. Caps 36″ and larger conform to XS specifications for wall Thickness of 36″. These are Wellgrow’s standards as no internationally recognized standars have been set for such large size wall thickness.

(1) The shape of these caps shall be ellipsoidal and shall conform to the shape requirements as given in the ASME boiler and pressure vessel code.
(2) Lentgh E applies for thickness not exceeding and that given in column “limiting wall thickness for lenth E”.
(3) Length E1 applies for thickness greater than that given in column “limiting wall thickness” for NPS 24 and smaller. For NPS 26 and larger, length E1 shall be by agreement between manufacturer and purchaser
