JKZ PWHT Machine Specification

Post-weld heat treatment (PWHT) is an important process for relieving stress. To meet code specifications and achieve its full potential, PWHT equipment such as JKZ’s is essential in fulfilling its purpose.

PWHT requirements vary based on pipe material and thickness; as a general guideline, one hour per inch.

EL 3000 Series Chart Recorder

The EL 3000 Series Chart Recorder is a robust instrument designed for general temperature and pressure applications. It records monitored temperature and pressure readings on a 12-inch diameter chart with room for up to four recording pens; temperature elements comprise helical Bourdon tubes connected directly to system piping while static pressure measurements use capillary tubing connected via connectors into the recorder case that attach to capillary tubing leading into capillary tubing in its lower portion which extends into its bottom for connection to system piping via system connectors attached capillary tubing which connects directly into system piping; additionally this recorder features a hinged door that allows access to its chart as well as maintenance operations;

The chart can be driven either by an electric motor or mechanical spring-wound chart drive (refer to Table 7.2 – Chart Drives on page 30 for details). The recorder provides multichannel simultaneous data acquisition using 35 thermocouple ranges and 8 DC voltage input ranges with universal input or mixed current/temperature as input sources, offering numerous display and operation functions such as vertical/horizontal trend, circular trend and marking function – in addition to Ethernet connectivity that facilitates remote monitoring by browser, FTP server/client functionality or alarm notification via E-mail.

The EL 3000 is easy to maintain and use. Routine maintenance includes replacing charts and pens as they wear out; winding of its spring-wound chart drive; periodic calibration; as well as the addition of recommended tools in each unit. Static pressure pen are calibrated by loosening mounting screws, moving their lift arm onto an appropriate time line on a chart time line and applying static pressure; then lowering them back down until their tip touches the chart surface before watching its pressure indicator move across its scale accurately – otherwise recalibration will be necessary.

Thermocouple extension and compensating cables transmit the thermoelectric voltage produced by thermocouples to measurement instruments. They are constructed from various insulating materials suited for their respective applications and usually color coded and identified with letters for easier identification; each type of thermocouple used can be easily identified using this letter system (KX, TX, JX etc). Furthermore, compensating cables may even use alloy materials which provide similar thermo-electric characteristics within an acceptable temperature range.

Most compensating cables are typically insulated with PVC. This material offers excellent service lifecycle and versatility in most applications; enduring high temperatures while remaining gas, steam and water tight; being flame retardant without softening when exposed to heat sources; or alternatively being made of XLPE which offers similar properties but better at withstanding higher temperatures without softening over time; additionally it boasts low smoke/halogen emissions which makes it suitable for contact with chemicals/oils etc.

Teflon insulation offers another method for compensating cable, being an inorganic compound with wide temperature tolerance, incombustibility and excellent insulating properties.

Heating Blankets

Heated blankets are a convenient and cost-effective way to stay warm at night, yet some can overheat and start electrical fires due to faulty wiring or misuse of the product. To avoid this risk, it is crucial that consumers check out all specifications and features before making their purchasing decision.

Manufacturers use specialized equipment to thread heating elements into blankets’ shells and weave their wires together into one continuous piece of cloth, which then gets filled with batting to help retain heat and then shipped off to consumers.

This plush blanket is constructed with microlight plush polyester that boasts an elegant silky feel and can be machine-washed for convenience. Additionally, its 11 heat settings range from low to high; its control has an intuitive user experience with an LED backlit display making use easier; durability has proven itself after multiple machine washes and dryer cycles without noticeable wear-and-tear or loss in functionality.

This electric blanket is an ideal option for those who wish to keep their bed warmer than other models. Featuring 20 heat settings – more than most blankets – as well as soft and thick material so wires are less visible, its controls are simple, and you can set its timer option for up to 10 hours, this blanket makes a good investment for keeping warm nights warm!

Induction Heating Devices

Induction heaters are compact heaters designed to focus heat precisely where it’s needed, easily set-up with flexible heating cables and user-friendly insulation blankets, featuring on-board power control with manual or temperature based programming and an intuitive operator interface. Furthermore, radiation pyrometers offer automatic feedback to maintain proper operation of the system.

With induction, energy is directly transferred from an energy source directly into the workpiece without losing heat through air or flame losses, providing for rapid heating rates, higher production rates, tight process control, precise application of energy only to desired areas and lower heating times – cutting heating times by almost 50% while decreasing energy requirements while simultaneously improving energy efficiency.

An AC current passing through an induction coil produces a magnetic field around a workpiece, and this induces it to generate its own eddy currents that counter the original magnetic field and absorb some of the electrical energy, creating heat. Eddy current strength depends on both frequency of AC current as well as coil shape/size/design; selecting appropriate options ensures optimal induction results for any industrial application that involves metalworking, manufacturing, brazing/soldering processes or heat treatment – for instance sterilization processes for medical uses.
