Seamless process

The major portion of drill string is composed of drill pipe. The drill pipe is manufactured by the seamless process. According to API Specification 5A (Thirty-fifth Edition, March 1981), seamless pipe is defined as a wrought steel tabular product made without a welded seam. It is manufactured by hot working steel or, if necessary, by subsequently cold finishing the hot worked tabular product to produce the desired shape, dimensions and properties. 

If you re looking far high-quality products and a seamless process from start to finish, consider BlueWater Mtg. Inc. far all your fall protection needs. 

Unlike conventionally knitted garments the seams of which tend to break up the continuity of the garment design, the seamless process allows patterns and designs to remain uninterrupted across the entire garment— front to back, over the shoulder. 

Manufacture and marking of rubber insulating equipment, (i) Blankets, gloves, and sleeves shall be produced by a seamless process. 

In the automobile industry most of the volume car manufacturers have established seamless processes with their first tier suppliers based upon providing immediate access to production plans and schedules. This enables just-in-time deliveries to be achieved without the need for major buffers of inventory at the first tier level,... 

Overall, in order to have a seamless process between marketing and sales, you need consistency in definitions and consistency in messaging. If marketing leads the charge on this, your buyers will have great experiences and sales can close more deals. 

Defects in finished components can sometimes be traced as far back as casting problems in the ingot or billet from which the component was eventually produced. Defects in welded tubes may be linked to defective metal or to the welding process itself Defects in seamless tubes can originate in extrusion or drawing processes. 

Seams. As defects, seams are distinct from weld seams and may be found in nonwelded (seamless) tubes. They are caused by crevices that have been closed by some rolling process but remain unfused. 

Seams. As a defect, a seam is distinct from the seam resulting from a welding process. Seam defects can be found in nonwelded (seamless) tubes. They can originate from blow holes or nonmetallic inclusions in the ingot and are caused by crevices that have been closed by some rolling process but remain unfused. At times, they will appear in a spiral pattern in tubes. Seams can be very tight and appear as hairlines on the surface. They can cause failure when the component is pressurized. 

The Nippon Steel Corporation in 1972 pioneered the use of continuous annealing lines , in which rolled steel sheet is heat-treated and quenched under close computerised control while moving. For this advanced process to give its best results, especially when the objective is to make readily shapable sheet for automobile bodies, steel compositions have to be tailored specifically for the process composition and processing are seamlessly tied to each other. Today, dozens of these huge processing lines are in use worldwide (Ohashi 1988). 

Oils or fats generally are introduced into the boiler from steam that has been contaminated by an industrial process. Although a high percentage of condensate return usually is a desirable objective, where contamination takes place, the returning condensate transports these contaminants throughout the steam-water system, clearly making a seamless boiler operation much more difficult. 

The process of rolled ring forging is used in the manufacture of seamless rings. A hollow cylindrical billet is rotated between a mandrel and pressure roll to reduce its thickness and increase its diameter. 

A wire crosshead die is used to manufacture wire coatings, which is illustrated in Fig. 11.10. This specialized die turns the melt flow 90° before it leaves the die. At this turn, the wire to be coated enters the melt stream and exits the die co-axially with the polymer. This process yields a seamless polymer coating around the wire. 

Electrodeposition of metal onto structured objects, such as circuits, is controlled in part by a template. At the same time, the deposit must fill all the recesses uniformly and seamlessly, the texture and crystal structure must fall within tolerances, and the quality of the features must be sustained over a large workpiece. The distribution of material within recesses or onto widely separated portions of the workpiece is subject to a limited number of macroscopic control-parameters such as applied potential and plating bath composition. Success therefore depends on exploitation of the natural pathways of the process. The spontaneous and unconstrained development of structure must be taken into consideration in the production of highly organized and functional patterns. 

As vitally important as the capabilities for experimental planning, screening, and data analysis are the procedures for preparation of inorganic catalysts. In contrast to the procedures usually applied in conventional catalyst synthesis, the synthetic techniques have to be adapted to the number of catalysts required in the screening process. Catalyst production can become a bottleneck and it is therefore necessary to ensure that HTE- and CombiChem-capable synthesis technologies are applied to ensure a seamless workflow. 

To understand how UPS has maintained its vigilance and continued to grow its business over a ninety-eight-year period while avoiding the death spiral of corporate arrogance, hubris, and insularity, one has to understand the UPS culture and the UPS operations research mentality. The two are so integrated and intertwined that they are seamless and both are perpetuated today at UPS through stories, processes, measurement systems, human resource policies, and leadership acts. 

Implementing this level of automation intelligence has been the most difficult to realize within manufacturing industries. That is, while automation controls integration of simple univariate instruments (e.g., a hlter photometer) is seamless, it is much more problematic for multivariate or spectral instruments. This is due to the tower of babble problem with various process spectroscopic instraments across process instrument manufactures. That is, the communications protocols, wavelength units and hie formats are far from standardized across spectral instruments, even within a particular class of techniques such as vibrational spectroscopy. Several information technology (IT) and automation companies have recently attempted to develop commercialized solutions to address this complex problem, but the effectiveness of these solutions has yet to be determined and reported.
