Metal pipe fittings
Metal pipe fittings can be classified according to different standards, mainly including the following:
Classification by material
Ordinary metal pipe fittings
Mainly used in low-pressure, normal temperature environment, the main material is carbon steel, etc.
Special metal pipe fittings
Used in special environments such as high pressure, high or low temperature, strong corrosiveness, etc.,
The main materials are high-grade stainless steel, low-temperature steel, pipeline steel, nickel, titanium, zirconium and other non-ferrous metals and composite materials.
Classified by function
Connecting pipe fittings
Used for the connection of pipelines, such as flanges, union joints, pipe hoops, clamps, ferrules, hose hoops, etc.
Pipe fittings that change direction
Such as elbows, elbows.
Pipe fittings that change pipe diameter
Such as reducer (reducer), reducer elbow, branch pipe table, reinforcing pipe. Add branch fittings: such as tee and tee.
Classified by shape and structure
T-connector:With center hole and branch pipe.
Straight-through connection: No branch pipe or additional holes.
Exposed steel joints: different in length and diameter.
Fixed fittings: suitable for flexible and rigid pipes.
Shock absorber: End actuated clamp type,joints with grids.
Classified by use
Industrial metal pipe fittings
Widely used in petroleum, petrochemical, chemical, natural gas, shipbuilding, electric power, medicine, gas, heating and other industries.
Metal pipe fittings for construction
Such as electrical metal pipe (EMT), rigid metal pipe (RMC), intermediate metal pipe (IMC), etc.
Classification by manufacturing process
Seamless steel pipe
Without welds, suitable for conveying high-temperature, high-pressure media or corrosive media.
Welded steel pipes
Including longitudinal welded pipes and spiral welded pipes, suitable for low-pressure fluid transportation.
Classified by special properties
Stainless steel pipe fittings
With high strength and corrosion resistance, suitable for a variety of industrial fields.
Copper pipe fittings
Used in the manufacture of cryogenic pipelines in heat exchange equipment, oxygen production equipment, and oil pipes and control system pipelines in mechanical equipment.
Die-cast solid elbows
These joints are manufactured from ultra-deep drawn steel (EDDS) to ASTM-A653 standards and are precision drawn to thickness tolerances within ±0.002.
All die-cast joints are made of galvanized material with a thickness of not less than G60 or above, and are chemically treated to prevent white rust.
Stand-up joints
Suitable for medium pressure applications and can be used as an alternative to welded joints. These joints range in diameter from 8 inches to 60 inches and are up to 16 gauge steel thicknesses.
In addition, full-sweep stand-seam joints are available in diameters ranging from 8 inches to 30 inches with a one-piece standard throat construction with 5 air holes.
Zinc alloy die-cast fittings
GIRPI HMA25 metal fittings, for example, are die-cast from zinc alloy and can be galvanized, sanded or chrome-plated.
This joint has a tight structure, no porosity, high strength, reliable connection with metal hoses, and beautiful appearance.
Die-cast fittings
Fast-fitting with a special fastening tool (die-casting tool) without the need for high technical skills.
It requires a certain amount of space to operate, but does not require heating equipment, and is suitable for environments with flammable materials.
Insert the stainless steel pipe into the die-casting joint, and use a special fastening tool to die-cast the joint to reduce the diameter from the center to the end of the insertion part to realize the connection between the pipe and the joint.
Aluminum alloy die-casting joints
Such as 40 diameter aluminum alloy round pipe joints cross cross, Y-shaped tee, etc., these joints are widely used in agricultural irrigation water pipes and other fields.
Type B die-cast zinc-aluminum alloy fittings: including straight and 90 degree elbow fittings, suitable for metal or non-metallic liquid sealing conduits.
These types of die-cast metal pipe joints have their own characteristics and advantages in different application scenarios.
Such as corrosion resistance, high strength, good sealing, etc., and are suitable for various industrial and construction fields.
Metal Pipe Fittings manufacturing process
Hydraulic cold forming process
Special metal pipe fittings usually adopt the international advanced hydraulic cold forming process, which can ensure that the pipe fittings maintain high precision and high quality in the manufacturing process.
Seamless steel pipe production technology
The manufacturing process of seamless steel pipe includes a variety of methods such as bolt rolling production, continuous rolling production, three-roller rolling production and extruded pipe production.
These processes are suitable for the production of steel pipes with different diameters and wall thicknesses.
Such as bolt rolling production is suitable for structural steel pipes with a diameter of more than 250mm.
While continuous rolling production is suitable for steel pipes with a diameter of less than 168mm.
Cold working technology
Cold working technology is used to strengthen metals and alloys to improve corrosion resistance and quality.
For example, stainless steel materials are becoming mainstream in the oil and gas and medical markets due to their corrosion resistance, formability, and cost-effectiveness.
Titanium tubing offers unique strength, density, and corrosion resistance for use in harsh environments such as aircraft hydraulics, medical implants, subsea equipment, and chemical plants.
Fabrication of special shapes and sizes
Fabrication of specialty tubing also includes the ability to customize special shapes and sizes.
For example, spiral boiler tubes form a rifle-like spiral pattern on the tube through a specially shaped mold to provide a more efficient heat exchange surface.
Fin heat exchanger tubes improve thermal efficiency by creating an extended surface on the surface of the base tube.
HAICHEN METAL PIPE FITTINGS
Different types of die-cast metal pipe joints have their own characteristics and advantages in different application scenarios, such as corrosion resistance, high strength, good sealing, etc.
And are suitable for various industrial and construction fields.
