What do they do best? They make custom polymer profiles that protect deep-sea cables. XLPE, TPE, and PVC materials go through their machines. Triple extrusion tech handles tough jobs. You get custom fillers with co-extrusion, post-coating, and semi-conductive materials.
Their umbilical products replace old-style ropes, tubes, and solid pipes. These profiles weigh less. You can adjust stiffness and flex to match your needs. Dimensions stay exact. Tolerance errors drop by a lot. Seabed setup becomes simpler. Fewer cable drums fit on the platform. Production speeds up.
Primo works in medical tubing, car gaskets, and subsea cable fields too. Low-friction profiles fit moving parts. Recyclable and energy-smart plastics reduce waste. Their tooling and design services help you go from basic sketches to finished drawings.
Need hydraulic tensioning equipment for wind turbines, power plants, or petrochemical sites? Check the other companies on this list. Primo does polymer work—not hydraulic bolt tensioners or torque tools.
8. BELIUM Hydraulic
BELIUM Hydraulic started in Hangzhou back in 2008. The parent company is Hangzhou Fuyang Tengming Industrial Co., Ltd. They build high-pressure hydraulic tools that reach 700 Bar. The basics are all here: cylinders, pumps, wrenches, and bolt tensioners.
Their cylinder lineup runs deep. BMSA single-acting and BMDA double-acting models use strong aluminum alloy. These weigh less than steel but keep the same strength. You get easy transport without losing power. They offer low height, hollow plunger, ultra low height jack, long stroke, high tonnage, and lock nut styles. Each one fits different job needs.
Pumps come in hand, foot, and electric versions. The 2022 Electric pump runs on 220V/50Hz/0.37KW. It’s compact and low-height. It reaches 700 Bar max. Hydraulic wrenches come in square drive and low-profile types. Flange spreaders, pullers, combi bead breakers, and compact jacks fill out the catalog.

9. TorcStark
TorcStark runs Pingyuan Jingke Hydraulic—the manufacturer we covered in Section 1. This isn’t a separate company. It’s just their export brand name.
The confusion makes sense. TorcStark shows up on international websites and product catalogs. Pingyuan Jingke Hydraulic appears in Chinese business records and domestic files. Same factory in Juncang Industrial Park. Same 20,000 square meter facility. Same team of 200 workers. Different names for different markets.
Why does this matter? You might reach out to both “companies” thinking you’re comparing suppliers. But you’re talking to the same sales team twice. Same products. Same prices. Same hydraulic bolt tensioners working in 170+ wind farms across China.
The office is in Room 1705, Building A, Da Data Industrial Base in Jinan High-tech Zone. The factory sits 100 kilometers away in Dezhou City. Many Chinese manufacturers use this setup. The city office handles export sales and customer service. The rural factory keeps costs low.
TorcStark focuses on English-speaking buyers. These buyers need hydraulic tensioning equipment for petrochemical plants, bridges, power stations, and offshore platforms. The brand offers PLC synchronous lifting systems and wind turbine tools. These replace foreign brands. Reach them at [email protected] or WhatsApp +86 18853117120.
10. SAIVS TOOL
SAIVS™ has twenty years of toolmaking history in China’s industrial belt. They make hydraulic bolt tensioners and precision torque equipment for high-risk sectors—energy plants, petrochemical refineries, aerospace facilities, and heavy engineering sites. Mistakes in these places cost lives.
Their TG-Series hydraulic tensioners handle bolts from 3/4″ to 4″ diameter. You need at least one bolt diameter sticking out above the nut. That’s your working clearance. No shortcuts work here.
The SDW Series square drive models cover 3/4″ to 2-1/2″ sizes. Hydraulic pistons give you controlled torque. Construction crews use these tools. So do oil and gas teams and manufacturing plants. They rely on them for critical joints. Spark-free operation keeps hazardous zones safe. One spark near volatile chemicals can kill.
You get tight accuracy. Electric hydraulic pumps hit ±3% precision. Hand torque multipliers stay within ±5% tolerance. These multipliers push 10,000 to 20,000 Nm through 1:28 or 1:76 ratios. Power reaches the fastener with zero guesswork.
Safety systems go deep. The SPA-70 pneumatic pump operates at 700 bar. Some systems reach 1,500 bar pressure. Pressure relief valves stop overload damage. Industrial-grade seals prevent leaks. Reinforced hoses take hits from sharp edges and rough handling.
Compact wrench heads fit tight spaces. Small tools deliver high torque output. This stops joint leaks and material damage. SAIVS offers a budget-smart alternative to Western brands. Chinese factory efficiency keeps prices low and delivery quick.
Certification marks decide if your bolt tensioner lasts five years or fifty. The data backs this up. Products without ISO or CE stamps fail five to ten times more than certified ones. This comes from fatigue strength tests under ISO 898-1 standards—not marketing claims.
ISO 9001:2015 certification tells serious manufacturers apart from basic shops. Boltight tensioners have LRQA ISO 9001:2015 approval plus CE marking. Each unit gets tested for build quality, oil filling, and pressure at 1,500 bar maximum. The payoff? You get precise, even fastening with zero friction.
Traditional hydraulic tensioners hit load accuracy at ±51%. That’s like flipping a coin. Certified gear tightens this to ±10% by industry rules. Grene WIS products meet CE rules under Pressure Equipment and Machinery Directives. This means real safety and reliability—not just paper trails.
Quality certifications beat basic compliance marks. ISO 9001:2015 handles quality control and green standards. It tops simple CE approval. Testing stays consistent. Products without certification show weaker fatigue strength. Certified units last five to ten times longer at HRC 36-40 hardness levels.
Bolt tensioner prices run from US$120 to US$7,000 based on technical grade. Higher cost doesn’t always mean it fits your needs better.
Budget tier (US$120-500) handles standard cylinders for M20-M50 bolts. Pressure caps at 700 bar. Maintenance crews use these on ANSI B16.5 flanges each day. Simple. Works well. Has limits.
Mid-range (US$500-2,000) gives you medium-pressure adapters for M50-M80 jobs. CE certification backs 1,500 bar strength. Oil pipeline teams count on this level. API 17D compatibility is included. Better precision. More uses.
Premium segment (US$2,000-7,000) brings high-pressure dual hydraulic systems with auto-retraction. These work on bolts over 4 inches (M100+). Custom bases squeeze into tight spots. Wind energy and petrochemical plants use these for 10+ years.
Here’s the math: Pick ±10% certified accuracy if build time and failure rates affect your profits. You slash build time by 50%. Failures drop five to ten times. Budget picks work for regular maintenance with good value. Premium tools pay off in special fields where downtime costs millions.
Chinese makers like Dongguan Shenghang and Tianjin ASPLS ask for 1 to 10 units minimum. Small batches let you test suppliers without big risk.
Stock costs matter. Ready-made standard parts ship in 1 to 4 weeks. Custom orders need 12 to 24 weeks. Keeping stock burns 20% to 50% of what you paid each month. Interchangeable adapter kits trim stock costs by 30% to 50%.
Diamond Member and Secured Trading badges on Made-in-China prove real makers. Tianjin ASPLS has these badges. Checked suppliers cut fake product risk by 50% to 75%. Mix platform checks with ISO/CE papers. Returns fall below 5%. Go for ready-made standard items to skip custom order waits.
Wind power needs tight precision at ±10% accuracy. Turbine bolts measure M100+ across. CE and Pressure Equipment Directive rules are required. Torque wrenches pair with tensioners. Tower lifting match-up is a must—not extra.
Petrochemical sites need ANSI B16.5, MSS SP44, and API 17D rules for pipeline flanges. Pressure hits 1,500 bar. Standard cylinders team up with bridges and pullers. Even, friction-free fastening stops leaks that can kill workers.
Nuclear power calls for custom bases in tight spaces. Bolts go past M100. Heavy-duty ratings beat 700 bar. Auto-retraction and dual-drive T-Coax links take on extreme loads. Ultra-high hydraulic pressure is standard—not a bonus feature.
Tensioner setup needs pressure tests and stretch sensors at ±5% preload tolerance. Hydraulic systems run multiple bolts at once. ISO 16047 fatigue tests prove long-term strength. Skip these checks and you risk structure failure at every joint.
