High Precision Tube Plate Drilling and Thread Tapping Machining

Jetvision provides professional high precision tube sheet drilling and thread tapping machining services for heat exchanger, pressure vessel and boiler equipment, strict tolerance control, stable quality and custom processing available.

Tube sheet is one of the core key components widely used in heat exchangers, pressure vessels, boilers and various industrial thermal equipment. Its drilling accuracy and thread machining quality directly determine the assembly tightness, service life and overall operating stability of the whole equipment. High precision tube plate drilling and thread tapping machining has become an essential processing procedure in industrial equipment manufacturing.

In actual production and machining, tube sheets are usually made of carbon steel, stainless steel, alloy steel and other different metal materials. Due to dense hole distribution, high position accuracy requirements and strict verticality standards, ordinary machining methods are difficult to meet the industry production standards. Our factory adopts advanced CNC drilling and tapping equipment to complete all processes from positioning drilling, hole finishing, chamfering to standard thread tapping in one stop.

Before formal processing, we will carry out accurate calculation of bottom hole diameter according to different thread specifications and workpiece materials, effectively avoid thread incomplete tooth shape, tap breaking, sliding thread and other common processing problems. For blind holes and through holes on tube sheet, we adopt matched tap types and reasonable cutting speed, equipped with professional cooling and lubricating fluid to reduce tool wear and improve thread surface finish.

All finished tube plates are inspected strictly by professional testing tools. We control the hole position deviation, hole verticality, thread pass and stop gauge within the qualified range, ensuring each processed tube plate can perfectly match heat exchange tubes, connecting pipes and other accessories without assembly deviation and sealing leakage.

We support customized tube sheet drilling and tapping processing according to customer drawings, including different plate thicknesses, hole spacing standards and various standard and non-standard thread machining. Whether it is mass production or small batch customized processing, we can always maintain consistent high precision processing standards and deliver goods efficiently.

With rich experience in industrial metal plate deep processing, our high precision tube plate drilling and thread tapping products have been well recognized by overseas customers in machinery, chemical industry, electric power, metallurgy and other fields. We keep optimizing processing technology and improving production efficiency, and strive to provide global buyers with cost effective, stable and reliable tube sheet machining solutions.
