The boiler manifold headers are tie multiple steam carrying pipes, which are widely used in a boiler room as a distribution hub in all steam boiler generators and hot water boiler heating systems. The boiler manifolds can be available with customized zones. In order to guarantee premium quality, our boiler manifold headers must be drilled precisely with a tight tolerance, then welded, manufactured, and heat treated. Before leaving factory, all boiler manifolds must be pressure-tested.

Two-component composite spunbonded nonwoven fabric is the development direction of the world's spunbond technology. At the annual meeting at the end of 2004, the China Spunbond Nonwovens Industry Association will focus on the research of two-component spinning technology as the industry's recent development direction. The development of two-component composite spunbonded nonwoven fabric will greatly expand the development of spunbonding technology and products. It can melt melt-spun polymer materials such as polyester, polypropylene, nylon, polyester and other materials. Different kinds of fibers and webs with different properties are formed by different composite methods, so that the products of the spunbond fabric become rich and colorful, and the use is more and more widely used.
At present, there are not many varieties of spunbonded non-woven fabrics in China. The raw materials are concentrated in polypropylene and polyester. More than 80% of them are polypropylene hot-rolled fabrics, and the rest are polyester and spunbond/meltblown/spunbond (also known as SMS) products. . However, the two-component composite spunbond products that are urgently needed in some domestic industries are still blank, and user companies have to import from abroad at high prices. In the case of urgent market demand, Pacific Electromechanical Shanghai Textile Machinery Complete Co., Ltd. and Shanghai Synthetic Fiber Research Institute have successfully developed the first domestic two-component composite spunbonded nonwoven fabric production line after years of research.
In recent years, the Shanghai Institute of Synthetic Fibers has studied the two-component composite spunbonded nonwovens process and equipment, mastered the basic process and equipment technology of the two-component composite spunbonded nonwoven fabric, and built the domestic An experimental production line combining the two-component composite spinning and the spunbonding process into a web forming process has reached the current international advanced level and laid the foundation for the differential development of the spunbond method in the future.
In order to realize the localization of the two-component composite spunbonded nonwovens production line at an early date, the only Pacific Electromechanical Shanghai Textile Machinery Complete Set Company that can provide large-capacity polyester staple fiber complete sets of equipment, relying on Pacific Electromechanical “set, brand, service†Advantages, a lot of energy for the development of the production line. Pacific Electromechanical Shanghai Textile Machinery Complete Company has 23% of the total number of employees in the fields of chemical fiber technology, mechanical design and manufacturing, public engineering, on-site communication and control. Over the years, Pacific Electromechanical Shanghai Textile Machinery Complete Co., Ltd. has accumulated rich experience and unique technical patents in the design and manufacture of polyester staple fiber equipment, and has extensive and in-depth technical cooperation with internationally renowned chemical fiber machinery manufacturers and engineering companies. It has gathered a group of talents in chemical fiber mechanical design, process driving, engineering design and electrical digital control design, and is in a leading position in China.
The polyester filament yarn (FDY, POY) spinning machine, polyester staple fiber spinning combined machine and polyester staple fiber combined machine designed and manufactured by Pacific Electromechanical Shanghai Textile Machinery Complete Co., Ltd. enjoy a good reputation at home and abroad, and can provide single-line production capacity of 15 Polyester staple fiber combiner with tons/day~200 tons/day (7500 tons/year~60,000 tons/year), and can provide large-capacity composite spinning, three-dimensional hollow and nylon complete production lines, and can also be designed and manufactured according to customer's special requirements. Renovation of chemical fiber production lines and stand-alone equipment.
In recent years, Pacific Electromechanical Shanghai Textile Machinery Complete Co., Ltd. has provided and supplied large quantities of 30,000 tons and 50,000 tons of high-capacity polyester to Sinopec Yizheng Chemical Fiber Co., Ltd. and Sinopec Shanghai Petrochemical Co., Ltd. There are 36 fiber production lines and 7 spinning machines, and 4 post-processing combined machines and complete production lines have been provided to foreign countries.
Domestic two-component composite spunbond production line came out
Recently, the first domestic production line with a production capacity of 3,000 tons of two-component composite spunbonded non-woven fabric spinning machine was successfully developed. The composite spinning production line was first developed and developed by Pacific Electromechanical Group Shanghai Pacific Textile Machinery Complete Equipment Co., Ltd., and the Shanghai Synthetic Fiber Research Institute is responsible for process debugging and technical guidance. The equipment has an international advanced level and fills the domestic gap.
