In this article, we talk about hyd hoses and steel wire hoses respectively. Let you have a basic understanding of these two products.
What is steel wire hose and the use of NBR steel wire rubber hose
Steel wire hose also known as NBR steel wire rubber spiral reinforced hose, NBR hose industry production NBR industry called steel wire rubber spiral reinforced hose “steel wire rubber hose.”
NBR steel wire rubber hose using steel wire rubber reinforced NBR hose, the product NBR plastic as the main body, embedded spiral steel wire rubber as a reinforcing layer, product rigidity and flexibility, sufficient mechanical properties and rigidity, with excellent flexibility.
NBR steel wire rubber hose can be divided into industrial level (specializing in conveying industrial water, oil, sewage, powder, chemical raw materials, etc.) and food level (food factory conveying juice, milk, edible water, winery conveying white wine, beer, etc.), wind power, drainage, oil, low concentration of chemicals and other liquids and solid particles, powder materials. Regardless of the coating used, the material itself must be “non-corrosive” and “low concentration of chemicals”.
NBR steel wire rubber hose with embedded steel wire rubber skeleton NBR hose. The smooth inner and outer walls, no bubbles, and fluid transportation are visible; low concentration of acid and alkali resistance, high elasticity, not easy to aging, long service life; high-pressure resistance, can be maintained under high-pressure vacuum in its original state.
How to identify the steel wire rubber braided hydraulic hose models
The appearance of the hose is marked:
Such as the national standard example: Ruhr / GB / – / 2SN / 16 / /
- “Ruhr” is the manufacturer’s name or logo or logo
- “GB / -“ is the implementation of the standard
- “16” is the nominal inner diameter
- “2SN” is the type (1SN and is a layer of steel wire rubber braided hose, 2SN and two layers of braided hose)
Hyd hose basic knowledge
Hyd hose, also known as high pressure hose, generally divided into steel wire rubber braided hydraulic hose and steel wire rubber winding hyd hose.
General steam high temperature hose is mainly fiber braided hose, corrugated hose has PTFE tube. Among them, fiber braided hose has the advantages of heat resistance, high temperature resistance, and uniform steam distribution.
Generally speaking, fiber braided hose is used for hanging and scalding opportunities with small steam pressure; corrugated hose has the advantages of high temperature resistance, acid and alkali resistance.
Corrugated hose will be used for hanging and scalding machine or industrial steam industry with high steam pressure in general. There are many types of reinforcement layers for abrasion resistant sandblasted hose, including classifications for different environments in lowor high pressure environments, including fabric reinforcement + spiral reinforcement = mostly for low working pressure applications; cord reinforcement + steel wire rubber spiral reinforcement = mostly for high pressure applications.
Abrasion-resistant sandblasting hose is widely used for rust removal, sand recycling, concrete and other construction works such as rust removal, sand recycling and concrete transportation. Its super abrasion-resistant characteristic extends the service life.
Braided steel wire hose can be used to convey chemical gases and solvents at high temperatures and pressures.
In addition, the hose body can provide a flexible connection between steel pipes in the retention system. It is widely used in industrial fields such as hydraulic supports in mines, automatic hydraulic systems for oilfield extractors, mining engineering, and especially for hand drilling components.
The hose body can withstand -400℃~+100℃, the highest temperature +125℃ continue to work in the environment.
The surface of steel wire hose can be divided into smooth surface and fabric surface. In the oil drilling equipment industry, companies with advantages have strong innovation ability.
Over the years, the company’s investment in technology research and development has been increasing, and the level of production technology has been rapidly improved. In addition, with the improvement of the technical level of the upstream materials and machinery industry, the product technology level, processing precision and technical indicators of China’s oil drilling equipment industry have been improving, and the gap with foreign oil drilling special equipment industry has gradually narrowed.
High-temperature and high-pressure steam hose military enterprise certification department was established on the day of the STRUBB on the relevant R & D personnel to carry out professional training and research, mainly in order to make the R & D and manufacturing completely confidential, do not disclose any product information.
The work in China is subject to stricter working conditions to deal with military orders. Strict quality control and no defects are the minimum standards for the production of military products.
Obtaining certification from a military company signifies a new development for STERUBB in a new field. STERUBB pursues more breakthroughs in steady development, and keeps creating miracles and breaking through difficulties on the basis of the original development.
PTFE corrugated hose is characterized by corrosion resistance, high temperature resistance, low temperature resistance, light weight, small volume, good flexibility, and easy to use.
This series of hose products include oil transfer and suction hose, steam hose, sand blasting hose, acid and alkali transfer and suction hose, food hose, oxygen suction hose and all kinds of shaped hose, etc.
PTFE Corrugated Rubber Hose is widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries.
