The structure of this kind of product consists of two semi-circular card Board, set at one end a fixed-wing, set on a fixed-wing referred to through the screw connection screw; two semi-circular card described by axis hinged at the other end of the Board, as described in set the lifting holes on the fixed-wing.
 
This products and existing technology compared to, the end of hanging card comparison smooth, can avoid the end insert close to the other Hose  makes transport more security; due to the Oilfield Hose hanging card of end for axis hinge connection, through another end by of connection screw rod can makes two a semi-circular card Board will pipeline card of more tight, not only can avoid connection screw rod in transport in the loose of problem, and installed more convenient, and structure more simple.

 

 

Q:Our company to purchase a number of fasteners to see when the CAD drawings in the technical requirements I do not know the specific to write those content
Fasteners are generally standard parts, have national standards (except for special requirements)
Q:In the fastener industry, 1018 refers to what material
Low carbon steel, generally used for the production of self-tapping screws and screws and other low-strength fasteners products. 1018 steel chemical composition percentage: carbon C: 0.17-0.24; manganese Mn: 0.7-1.0; nickel Ni <= 0.25; phosphorus P: <= 0.035; sulfur S: <= 0.035; silicon Si: 0.17-0.37; <= 0.25; copper Cu: <= 0.25 domestic commonly used 18A and 22A material, carbon 0.18%. Domestic steel mills are now used daily SWRCH18A
Q:For the commonly used standard parts, for some of the quality of good or bad, how to distinguish,
The appearance of a color, thread through the rules, type size, such as head high, diagonal, opposite, thread length and so on. Mechanical properties include tensile strength, core hardness, decarburization, carburizing, and the like.
Q:Who include who btween them?
Fasteners are said from the point of view of the action, which contains both standard parts (GB ANSI ASME DIN EU JIS, etc.) and non-standard parts (according to the drawings) is not entirely a concept
Q:Bolts and other connection fasteners some points A B C grade what it means
Grade is not the same, the tolerance range is not the same, A-level tolerance of the smallest, C-class tolerance of the largest
Q:High-strength screw standard parts of the quality of what data
Material: Does the chemical composition meet the standard requirements Appearance: Good surface treatment: Does it meet the standard requirements? If 1 and 4 problems, this batch of bolts directly failed,
Q:what parts do Fasteners include
nut: with a threaded hole, the shape was generally flat hexagonal cylindrical, there are flat square or flat cylindrical
Q:Does the fastener include screws?
Fastener fasteners are also known as standard parts on the market and are a generic term for a class of mechanical parts that are used when two or more parts (or components) are tightly connected as a unit. It is characterized by a wide variety of specifications, performance purposes vary, and standardization, serialization, the degree of generalization is very high. Fasteners are the most widely used mechanical base pieces and are in great demand.
Q:What is the name of the screw (fastener)?
By hole type: a. Through hole b. Blind hole Material: a. Iron (Fe) b. Aluminum (Al) c. Stainless steel (sus)By color: a. Colorful (character) b. Blue zinc c. Black zinc
Q:Is it hard to heat the fasteners?
Fasteners are also known as standard parts, which are mainly heat-treated according to the material of the product.
