PWHT (Pre-Weld Heat Treatment) is an integral part of welding that ensures components perform as intended under various service conditions. Our PWHT machines feature fast heating speeds for fast weld seam and fillet treatment and come complete with PLC touch screen interface for ease-of-use.
Temperature Control
PWHT (Post Weld Heat Treating) is used to maintain an ideal temperature within weld metals and reduce residual stresses that could otherwise lead to distortion or cracking of welds. PWHT is particularly crucial when working with carbon steel components as these materials often come under stress from high levels of stress and heat which may cause distortion or reduction of mechanical properties; furthermore it protects welds against oxidation and corrosion.
pwht machines feature air cooling circuits to minimize operational costs associated with water cooling. Furthermore, temperature controllers offer more accuracy and allow curve recordings. Furthermore, PLC touch screens make operation simple with soft induction coils easily windable onto different work pieces.
Heating Coil
Heating coils are at the core of every heating system. Electric coils convert electrical energy to thermal energy via resistance within their coil, producing heat while simultaneously raising temperatures within their target object or area.
Heating coils come in many varieties, each designed for specific purposes. Open heating coils feature electric elements made of nickel and chromium that have been formed into tubing for structural support and protection from harsh environments. Other available materials may include stainless steel, copper, and titanium.
Tubular heating coils consist of metal tubes filled with an insulating material such as magnesium oxide powder to minimize current leakage and improve thermal efficiency, and are more durable than open-wound designs.
The heater coil can either have a helical or longitudinal coil shape. Helically wound designs provide more surface area for heating at faster rates, helping prevent coking or early wear; on the other hand, longitudinal coils may cause warping and deformation to your workpiece.
Heating coils have become an indispensable component of modern life and industrial processes. Heating coils can be used to harden various metals like steel, cast iron, aluminum, titanium and bronze and even help thaw pipes and objects that have frozen over.
Insulation Blanket
Insulation blankets are a fantastic way to both safeguard equipment and create a more pleasant working environment in any facility. Insulation blankets help reduce energy costs by blocking cold air from entering and warm air from escaping, acting as physical barriers against high temperatures while protecting employees from burns or skin damage and decreasing noise produced by machinery – helping workers avoid hearing loss.
Removable insulation blankets offer many advantages over permanent insulation in terms of installation time and ease. Available in an assortment of chemistries, thicknesses and densities to meet various applications and temperature ranges, they can save thousands in energy costs while improving thermal process performance and providing fire protection characteristics – plus they require no curing time before rolling away for maintenance operations!
Thermal insulation blankets are tailored to fit machinery tightly, helping retain heat efficiently, prevent condensation, dampen vibrations and noise pollution, as well as providing access to control valves or other components without impeding on their performance. Their removable design means they can provide insulation while still giving access to critical components like valves.
Insulation jackets are similar to blankets, except they’re tailored specifically for each component they cover and secured using D-rings, slide buckle straps or tie wires. Insulation jackets are useful when the size and manufacture of pipe components are unknown or when temporary insulation is required – typically featuring cutouts for valves and controls along with flexible designs to fit equipment of all shapes and sizes.
