A tube sheet is a plate, sheet, or bulkhead which is perforated with a pattern of holes designed to accept pipes or tubes. These sheets are used to support and isolate tubes in heat exchangers and boilers or to support filter elements, are the most common used in oil refineries and large chemical plants. Depending on the application, a tube sheet may be made of various metals. A sheet tube may be covered in a cladding material which serves as a corrosion barrier and insulator and may also be fitted with a galvanic anode. Tube sheets may be used in pairs in heat exchange applications or singularly when supporting elements in a filter.   Changrun manufactures various tube sheets (plate sheets), baffles, and support plates, including Overlay welding and explosion cladding. Materials include Carbon Steel & Alloy Steel, Stainless Steel & Duplex Steel, Nickel & Nickel Alloys, Titanium & Titanium Alloys.   Manufacturing Capacity: OUTSIDE DIAMETER: Maximum Ø5000MM for Tubesheet (Tube Plate) Maximum Ø6300MM for Ring & Flange THICKNESS: Maximum 750MM TUBE HOLE DIAMETER: Maximum Ø120MM  

  Baffles plate are an integral part of the shell and tube heat exchanger design. A baffle is designed to support tube bundles and direct the flow of fluids for maximum efficiency. Baffles can come in various forms and designs, depending on the specific application and requirements. Some common types of baffles include: Solid Baffles, Segmental Baffles, Disc and Doughnut Baffles, Swivel Baffles. Material include: Carbon steel, Stainless Steel & Duplex Steel, Nickel & Nickel Alloy, Titanium & Titanium Alloy, Copper & Copper-Nickel.   

  Pipe fitting are key elements of a piping system and are used in various industries, such as oil and gas, petrochemical, manufacturing, etc. These flanges connect pipes to valves or equipment or with another pipe spool and form a tight seal that prevents leaks and ensures efficient fluid flow within the system.   Flange Manufacturer Changrun supplies Weld Neck Flange (WN), Long Welding Neck Flange (LWN), Lap Joint Flange (LJ), Blind Flange / Blank Flange (BL), Slip On Flange (SO), Thread Flange (THR), Socket Weld Flange (SW), Reducing Flange, Orifice Flange, Anchor Flange, Spectacle Blind Flange (Figue 8), Spacer Ring/Spade Flange etc…Material include: stainless steel, carbon steel, alloy steel, duplex & super duplext steel, neckel alloy or special material.  

  Q-Lip Nozzles   A Q-lip nozzle is a unique connection design that contains a Q-lip (insert lip) that is welded directly into the pressure vessel wall during the fabrication assembly. This allows for simpler and economic installation, as well as easier and less costly weld inspections. The design also provides superior toughness and ductility in high stress areas. It is essential when the pressure vessel design requires capability of withstanding cyclic loading conditions during its service in the field. The most common application for this type of a connection is when an existing nozzle on the pressure vessel requires replacement.     Forged Integrally reinforced nozzle Flange   When the term "integrally reinforced nozzles" is used in a spec, it generally mean to say a "one piece" forged nozzle that has the reinforcement included in the neck and the flange is also forged with the body.   In power generation, oil and gas, and other industries, pressure vessels have been one of the major infrastructural components. Pressure nozzles are heavy-duty additions that facilitate the inflow and outflow of these fluids from the pressure vessel for further processing. Adding the nozzle to the vessel requires creating an opening on the vessel and joining the nozzle to it.   Nozzle Materials:Carbon Steel:  ASTM A105/A105N              A350 LF1, LF2 CL1/CL2, LF3 CL1/CL2              A694 F42, F46, F48, F50, F52, F56, F60, F65, F70             A516.60, 65, 70 (Spectacle Blind Flange, Spacer Ring/Spade Flange)             Steel RST37.2, C22.8Stainless Steel: ASTM A182 F304/304L, F316/316L, F316H, F316TI, F310, F321;Alloy Steel: ASTM A182 F1, F5, F9, F11, F22, F91Duplex & Super Duplext Steel: ASTM A182 F51/UNS S31803, A182 F53/UNS S32750, ASTM A182 F55 / UNS S3260 Flange Norminal Diameter Range: 1/2” – 96”, DN15-DN2000 Normail Pressure Range: 150# - 2500# (PN6 – PN40)

  Blind flanges manufactured in accordance with ASME B16.5 can be provided in Class 150 through Class 2500. It is basically a circular disc that does not have a hub or bored center. Bolts holes are drilled and aligned symmetrically along the circumferential edge of the solid disc. Generally the blind flange may be furnished with raised face, ring join face, or flat face. The blind flange serves a function similar to that of a plug or cap and is used to blank off the end of piping, valves and pressure vessel openings. It may be fabricated from cast, forgings, specific plates, or flat bars.   Blind Flange manufacturer WuxiChangrun supplies Blind Flanges, Industrial Blind Flanges, Blind Fittings in alloy steel, carbon steel, stainless steel, etc.  

  A slip-on flange is connected to the pipe or the fittings by two fillet welds, one executed inside and one outside the cavity of the flange. Slip-on flanges are also defined “Hubbed Flanges” and they are easy to recognize due to their slim and compact shape.   Wuxi changrun manufacturing SO flanges in accordance with ASME B16.5  can be provided in Class 150 through Class 2500. Materials include Carbon Steel & Alloy Steel, Stainless Steel & Duplex Steel, Nickel & Nickel Alloys, Titanium & Titanium Alloys.
