Group consists of six companies, in addition to HeNan WESDOM Import
and ExportTrading Co., Ltd. which is specialized in the import and
export of foreign trade, the other five companies all producing
factories, mainly located in Tianjin, Hebei, Liaoning and Zhejiang.
The major products for a variety of valves of cast iron, steel,
stainless steel, copper materials; malleable iron and stainless
steel pipe fittings; ductile iron, stainless steel fittings;
flanges and other products, mainly used in construction, petroleum,
chemical, power, water supply and drainage, municipal, medical
people's livelihood and other industries.
The company is now in addition to meet the domestic market, but
also to develop foreign trade, the company's products have been
exported to Europe, North America, South America, Southeast Asia
and other regions. Our products and services won the high praise of
The pipe joint is the connecting tool between the pipe and the
pipe, it is the connecting point between the component and the pipe
which can be disassembled.In the pipe fitting plays an
indispensable important role, it is one of the two main components
of the hydraulic pipeline.Pipe joints are used for straight line
connections such as meters, in the form of socket welding or
threaded connections.It is mainly used for low-pressure pipelines
with small diameter, for the parts that need to be installed and
dismantled frequently, or for the final adjustment of pipes with
threaded fittings.The structure form should adopt the metal surface
contact sealing structure, the gasket sealing structure form is
usually used to transport water, oil, air and other general
pipelines, using malleable cast iron material manufacturing.In
addition, use requirement and price also are the factor that
considers when choosing.
There are many kinds of pipe fittings. The commonly used pipe
fittings can be divided into two kinds: hard pipe fittings and hose
fittings.If according to the pipe joint and pipe connection, hard
pipe joint has flaring type, sleeve type and welding type three,
the hose joint is mainly the gusset type rubber pipe joint.
Hydraulic system in the pipe and pipe joint connection mode is
different, the pipe screw-in using the connection thread.The taper
thread is tightened with its own cone and sealed with teflon and
other materials. It is mainly used in middle and low pressure
hydraulic systems.Fine thread sealing effect is very good, is often
used in high pressure systems, but it requires the use of a
combination washer or o-ring for the end of the closure work,
sometimes use copper washer, it is more suitable for the connection
wall is thicker in the pipeline, its components are mainly joints,
nozzles and nuts.When in use, insert the joint body into the
target, and use the gasket mentioned above to seal the end face.
Rubber seal is used between the joint body and the pipe, and
sometimes spherical seal is used.
Because the pipe joint belongs to the dismountable connection
element, it must meet the requirements of normal connection
stability, strong sealing, reasonable size, small pressure loss,
good process performance and so on, but also must meet the
requirements of disassembly and installation convenience.Therefore,
do not underestimate the small pipe joints, because only its
existence can support the entire hydraulic system.
