In-Depth Exploration of the Pre-Shipment Inspection Process Pre-shipment inspection is a critical aspect of ensuring the quality and integrity of goods before they are dispatched. This process involves a series of meticulous steps and evaluations to safeguard the interests of all parties involved. The first stage of the pre-shipment inspection process typically begins with the gathering of relevant information. This includes details about the order, the products to be inspected, and the specific requirements and standards that need to be met. Inspectors thoroughly review the documentation to gain a clear understanding of what is expected. Once the information is gathered, the inspection team proceeds to the actual inspection site. Here, they carefully examine the goods themselves. This includes inspecting the physical appearance, checking for any visible defects or damage, and ensuring that the packaging is adequate and secure. They may also measure and verify the dimensions and specifications […]

Mineral processing plants require a storage buffer to bridge differences in production rates betweenmining and processing. Where coarse ores are processed, such as coal or hard rock, this buffer maybe an ore stockpile or silo. For wet-mining processes, e.g. dredging or hydraulic mining, or where f ine ores are slurried close tothe mining face, a surge-bin is used to contain the plant feed and smooth out the variations in miningrates. These bins have gradually evolved from simple storage vessels to units that are now frequentlypart of the mineral separation process itself, such as providing a desliming function to removedeleterious ultrafine gangue. This feed conditioning is often essential to achieve the levels of plantperformance required in times of declining ore grades and or where inherent ore characteristicsmake separations harder to achieve. To achieve these dual roles requires careful consideration of bin design factors such as geometryand lining selection and increased use […]
Trenchless Technology Trenchless Construction Drilling Pipe Trenchless technology represents a kind of subsurface construction methodology that necessitates minimal or no continuous trenching. Constituting a swiftly expanding segment of the construction and civil engineering domain, it can be delineated as “a set of techniques, materials, and machinery that can be employed for installing fresh or substitute underground infrastructure, or for revamping the prevailing ones, with negligible interruption to surface traffic, commerce, and other pursuits.” Trenchless Technology Trenchless Construction Drilling Pipe Trenchless construction encompasses various methods such as tunneling, microtunneling (MTM), horizontal directional drilling (HDD), also referred to as directional boring, pipe ramming (PR), pipe jacking (PJ), moling, horizontal auger boring (HAB), and other underground pipeline and cable installation techniques that minimize excavation. Large-scale subsurface projects like those employing a tunnel boring machine (TBM) or drilling and blasting methods are extensions of this concept on a grander scale. The distinction between trenchless […]
JSC is an ISO 17025 NDT Lab / Company (CNAS) ISO/IEC 17025:2017 is an international standard specifying requirements for quality and competence in testing and calibration laboratories. The standard requires that such labs prioritise excellent quality practices and develop a reliable quality management system to establish and demonstrate their competence. The full standard is called ISO/IEC 17025, since the certification was created by the International Organization for Standardization in conjunction with the International Electrotechnical Commission. However, many shorten this to ISO 17025 or simply 17025 certification when referring to the standard. Ultimately, ISO 17025 is for any organization that performs testing, sampling or calibration and wants to be sure of the reliability of their results. The simplest way we can put it: if you work in a testing environment that produces measurable results, then ISO 17025 is probably applicable. This may even mean you don’t necessarily call your facility a […]

Stainless Steel – Fabrication: An Insight into the Material and Key Considerations During Fabrication Stainless steel, known for its corrosion resistance and durability, is a crucial material in the fabrication industry. Its unique properties make it suitable for a wide range of applications, from industrial equipment to architectural structures. In this article, we will delve into the nature of stainless steel, explore its fabrication process, and highlight the key considerations during the process. What is Stainless Steel? Stainless steel is an alloy of iron with a minimum of 10.5% chromium. The chromium content forms a thin, invisible, corrosion-resistant layer on the steel’s surface, protecting it from oxidizing and rusting. In addition to chromium, stainless steel may also contain other elements such as nickel, molybdenum, titanium, and nitrogen, which further enhance its properties. Stainless steel is classified into several types based on its composition and properties. The most common types include […]
